Diversey Suma

Suma Grill D9 is a highly alkaline cleaning product from Diversey, formulated specifically for the periodic deep cleaning of heavily soiled commercial ovens, grills and salamanders. It combines alkali, surfactants and solvents to cut through carbonised grease and baked-on food residue that routine daily cleaning products are not designed to tackle.

In a busy commercial kitchen, carbonised soiling builds up quickly on oven cavities, grill plates and salamander elements — particularly during high-volume service. Suma Grill D9 is intended for periodic use rather than daily application, giving operators an effective way to restore equipment to a hygienic working condition without excessive scrubbing. When diluted with water it can also be used for soak-cleaning fryer baskets and pots, making it a practical multi-purpose cleaner for the back-of-house environment.

Practical benefits for kitchen teams include:

• Removes stubborn carbonised deposits that standard degreasers leave behind
• Suitable for ovens, grills, salamanders and soak-cleaning fryers
• Ready-to-use trigger spray format for straightforward application
• Supplied as a pack of six, reducing reorder frequency for busy sites
• Proven Diversey formulation widely used in professional catering environments

As with all highly alkaline cleaners, appropriate personal protective equipment — gloves and eye protection — should be worn during use, and the product should not be applied to surfaces it is not specified for. Always follow the manufacturer's dilution and contact-time guidance to get the best result without risk of surface damage.

This product suits catering operations of most sizes where ovens, grills or salamanders are in regular use — from pub kitchens and cafés through to high-volume restaurant and contract catering environments. It is a straightforward periodic cleaning consumable rather than a daily-use product, so order frequency will depend on how intensively the equipment is used.

If you are unsure which cleaning products are appropriate for your specific equipment or kitchen setup, our team is happy to point you in the right direction.

Suma Chlor D4.4 is a concentrated rinse additive formulated specifically for the hygienic preparation of salads, tomatoes, and raw vegetables. It uses a stabilised chlorine solution to reduce microbial contamination during the washing process, helping kitchens meet food safety requirements without compromising the taste or appearance of fresh produce.

In a busy kitchen environment, consistent produce hygiene is a practical necessity rather than an optional step. D4.4 is effective at low water temperatures, which suits kitchens that wash salad ingredients in cold or cool water as part of standard prep. Because it does not taint the vegetables, operators can use it confidently without affecting the end dish.

Practical advantages for kitchen teams include:

• Works effectively at low temperatures, suitable for cold-water vegetable washing
• Stabilised chlorine formula supports consistent, repeatable results across prep shifts
• Does not affect the flavour or presentation of washed produce
• Concentrated formulation helps control usage and running costs
• Supplied as a twin-pack, reducing reorder frequency in higher-volume operations

D4.4 is straightforward to incorporate into existing vegetable prep routines. No specialist dispensing equipment is required for standard use, though higher-volume sites with dedicated wash sinks may benefit from a measured dilution approach to ensure consistency. Storage should follow standard chemical storage guidelines — away from food contact surfaces and in a cool, dry area.

This product is well suited to any commercial kitchen that prepares fresh salads or raw vegetables as part of its regular menu — from cafés and pub kitchens through to contract catering and care home operations. If you prepare large volumes of fresh produce daily and want to discuss the most appropriate dilution rate or usage routine for your setup, our team is happy to help.

Suma Max D9.2 is an alkaline cleaning fluid formulated specifically for tackling the heavy, baked-on soiling that builds up on commercial ovens, grills, and salamanders. It combines alkali, surfactants, and solvents to break down carbonised grease and food residue — the kind of stubborn deposits that routine daily cleaning products struggle to shift.

In busy kitchen environments, oven cavities and grill plates accumulate carbonised soil quickly. Used as part of a regular cleaning regime, D9.2 helps prevent that build-up from becoming a time-consuming deep-clean problem. When diluted appropriately with water, it is also suitable for soak-cleaning fryer baskets and pots, giving it practical flexibility across more than one piece of equipment. Used with a foam sprayer and extension, it improves reach into deep oven cavities and reduces airborne mist during application.

• Cuts through carbonised grease on ovens, grills, and salamanders
• Suitable for soak-cleaning fryers when diluted with water
• Compatible with foam sprayer and extension for improved reach
• Supplied as a pack of six 750ml bottles for kitchen stock continuity
• Periodic-use formulation that supports a planned cleaning schedule

As with all concentrated alkaline cleaners, appropriate PPE — gloves and eye protection — should be worn during application, and surfaces should be rinsed thoroughly after use. It is intended for periodic rather than daily use on oven interiors, and should not be used on aluminium surfaces without checking manufacturer guidance first.

This product suits most commercial kitchens operating grills, char-grills, deck ovens, combi ovens, or salamanders as part of their equipment line-up. Sites with extremely high grill throughput — such as burger restaurants or grill-focused operations — may find they go through stock faster and should factor that into ordering quantities.

If you are unsure which Diversey cleaning product is most appropriate for your specific equipment or cleaning schedule, the team is happy to help you work that out.

Suma A5 is a concentrated rinse aid formulated for use in commercial warewashers — including undercounter, pass-through, and rack conveyor machines. It is a low-foaming product designed to promote rapid water sheeting from crockery, glassware, and utensils during the final rinse cycle, reducing water spotting and aiding faster drying without leaving residues.

In a busy kitchen environment, consistently spot-free results matter — not just for presentation, but for throughput. When rinse aid is properly dosed, ware exits the machine drier and ready to use sooner, which supports faster turnaround during service. Suma A5 is a well-established product in this category and is compatible with the dosing systems found on most commercial dishwashers.

Practical advantages of using a quality rinse aid concentrate like Suma A5 include:

• Reduces water spotting and streaking on glassware and crockery
• Aids faster drying, reducing handling time after the wash cycle
• Low-foaming formula suited to the rinse cycle in commercial machines
• Concentrated format means lower usage volumes compared to diluted alternatives
• Supplied as two 5Ltr bottles, providing a practical stock quantity for most sites

This is a consumable product intended for use via the rinse aid dosing inlet on commercial dishwashers. Correct dosing is important — both underdosing and overdosing can affect results, so it is worth checking your machine's dosing settings if you are switching from a different product or concentration. Your machine's service documentation or the manufacturer's guidance will indicate the recommended dosing rate.

Suma A5 is well suited to cafés, restaurants, hotels, contract caterers, and other foodservice operations running a commercial warewasher day-to-day. It is a straightforward, reliable choice for sites that want a proven rinse aid without unnecessary complexity.

If you are unsure about compatibility with your specific machine or want guidance on the right dosing level for your wash volume, the team is happy to help.

Pack Quantity: 2 x 750ml Divermite D2 refill bottles. For use with GC388 Divermite S Dispenser.

Suma Star D1 is a concentrated washing up liquid from Diversey, formulated for commercial use where grease, food residue and heavy soiling are a routine part of the washing cycle. It is intended for manual dishwashing and general pot wash duties rather than machine dosing, making it a practical choice for kitchen sinks and pot wash stations.

In a busy kitchen environment, a diluted domestic product often falls short — particularly during service when volumes are high and staff need a product that cuts through grease quickly without excessive re-washing. Suma Star D1 is designed to perform consistently under those conditions, producing a stable lather and releasing grease efficiently from cookware, utensils and food preparation surfaces.

As a concentrate, the 20-litre container offers good economy of use. Diluted correctly, it goes significantly further than a ready-to-use alternative, which matters in operations where consumable costs are managed closely. The container size also reduces how frequently stock needs to be replenished, which suits sites with limited storage top-up time during service.

• Effective on heavy grease and baked-on food residue
• Concentrate format reduces cost-per-wash compared to ready-to-use products
• Suitable for manual pot wash and general sink-side use
• 20-litre format suits regular commercial usage without frequent reordering

This product is well suited to cafes, pubs, school kitchens, care homes and similar operations where manual washing is a regular part of the day. Higher-volume sites with multiple sink stations may find it worth discussing quantities and dilution rates with us to ensure they are getting the best value from the product.

If you are unsure whether this is the right product for your operation or want to discuss dilution guidance and bulk options, the team is happy to help.

Suma D9 is a concentrated alkaline cleaner from Diversey, formulated to tackle the heavy soiling that accumulates on commercial grills, ovens, griddles, and similar cooking equipment. It is a well-established product in professional kitchens, used routinely where carbonised grease and baked-on fat need to be removed reliably as part of a hygiene programme.

In a busy kitchen, grill plates, oven cavity walls, and burner areas build up carbonised residue quickly during service. D9 is designed for exactly this kind of soiling. Because it is a concentrate, it can be diluted to suit the task — a lighter dilution for regular maintenance cleans, a stronger mix for periodic deep cleans. This flexibility also helps manage cost per use across a site.

• Dilutable concentrate — adjustable strength for routine and deep-clean applications
• Effective on carbonised grease, baked-on fat, and heavy oven soiling
• Two 5-litre containers per pack, reducing reorder frequency
• Suitable for a wide range of commercial cooking equipment surfaces
• Consistent, predictable performance from a proven Diversey formulation

As with any strong alkaline cleaner, there are practical considerations to keep in mind. Follow the manufacturer's dilution ratios and contact time guidance carefully, ensure the area is well ventilated during use, and confirm compatibility with the surfaces being cleaned. Aluminium components in particular can be sensitive to alkaline products, so checking suitability before use is advisable. Appropriate PPE should always be worn when handling the product.

D9 is well suited to kitchens with regular, heavy grill and oven use — high-volume restaurants, pub kitchens, contract catering sites, and similar operations where thorough equipment cleaning is both a hygiene requirement and a factor in equipment longevity. For sites with lighter cleaning needs, a less concentrated product may be more appropriate and more economical.

If you would like guidance on dilution rates for your specific equipment or want to confirm this is the right product for your cleaning regime, the team is happy to talk it through with you.

Pack Quantity: 2 x 5Ltr Concentrated hand washing up liquid.

Suma Scale D5.2 is an acidic descaler concentrate from Diversey, formulated to dissolve limescale and mineral deposits from commercial kitchen equipment. It is a well-established product used across catering operations for routine descaling of combi ovens, dishwashers, water boilers, urns, coffee machines, and similar water-fed appliances. This listing supplies two 5-litre containers, giving a practical stock quantity for ongoing maintenance schedules.

Hard water areas present a persistent challenge in commercial kitchens. Limescale build-up reduces heating efficiency, shortens equipment life, and — in the case of dishwashers and combi ovens — can affect wash quality and steam performance over time. Regular descaling with a proven concentrate like Suma Scale D5.2 helps maintain equipment at its operating specification and reduces the likelihood of costly downtime or premature component failure.

• Removes limescale and mineral deposits from water-fed equipment
• Acidic concentrate formula — diluted to suit different applications
• Suitable for combi ovens, dishwashers, urns, and water boilers
• Supplied as 2 x 5Ltr for practical stock management
• Part of the established Diversey Suma professional cleaning range

As a concentrate, dilution rates will vary depending on the equipment type and the severity of scale build-up. Always follow the manufacturer's guidance for the specific appliance being treated, and check compatibility if you are descaling equipment with stainless steel internal components or specialist coatings. Storage in a cool, dry location away from other chemicals is standard practice.

This product is well suited to kitchens in hard water areas operating high-use water-fed equipment, and to operators looking to consolidate cleaning chemical procurement with a single trusted supplier. If you are unsure which descaler is appropriate for a particular piece of equipment, or how frequently descaling should be scheduled in your operation, we are happy to advise.

Suma Bac D10 is a concentrated detergent sanitiser from Diversey, formulated for cleaning and sanitising surfaces in food preparation and service environments. It combines the cleaning and sanitising steps into a single product, making it a practical choice for kitchens looking to simplify their hygiene routines. This listing supplies two 5-litre containers.

In a working kitchen, consistency of sanitation matters as much as thoroughness. Suma Bac D10 is diluted with water before use, which means each container goes a considerable way when used at the recommended dilution rate. It is suitable for use on food-contact surfaces, work surfaces, equipment exteriors, and general kitchen areas.

As a concentrate, it offers some practical advantages over ready-to-use products:

• Tested to BS EN 1276 and BS EN 14476 for bactericidal and virucidal efficacy
• Single product covers both cleaning and sanitising steps
• Dilute-to-use format reduces storage space compared with ready-to-use equivalents
• Suitable for routine use across food preparation surfaces and kitchen equipment
• Compatible with standard trigger sprays or bucket-and-cloth application

As a dilutable product, correct dosing is important. Using too little may compromise sanitising efficacy; using too much increases cost without benefit. Following the recommended dilution guidance is straightforward and will be familiar to any kitchen team with basic hygiene training. This is a surface sanitiser and is not intended for use in dishwashers or other machinery.

Suma Bac D10 is well suited to catering operations of most sizes — from small café kitchens to larger contract catering environments — where a reliable, proven surface sanitiser is needed as part of a documented cleaning schedule. If you are reviewing your full kitchen hygiene programme or need guidance on product suitability for a specific environment, our team is happy to help you work through it.

Suma Break Up D3.5 is a concentrated liquid degreaser from Diversey, formulated for removing heavy grease deposits and baked-on soiling from commercial kitchen surfaces. It is designed for use on a wide range of kitchen surfaces including stainless steel equipment, extractor hoods, oven surrounds, fryer exteriors, and tiled walls — anywhere that grease and cooking residue accumulate over a service period.

In a busy kitchen environment, grease build-up is a constant operational challenge. Surfaces exposed to frying, grilling, and roasting can become heavily soiled in a single service, and standard cleaning products often require excessive dwell time or repeated application to achieve results. A dedicated heavy-duty degreaser concentrate like Break Up D3.5 is more effective in these conditions, cutting through carbonised deposits that milder cleaners leave behind.

As a concentrate, the product is diluted to suit the level of soiling, which means operators can adjust strength for routine cleaning versus deep cleans without switching products. This also makes the two-pack format practical for sites that carry out regular scheduled cleans alongside daily surface maintenance.

• Concentrated formula allows dilution to suit light or heavy soiling levels
• Effective on grease-laden surfaces including fryers, hoods, and oven exteriors
• Supplied as two 5Ltr containers, reducing reorder frequency for busy sites
• Suitable for a wide range of non-porous commercial kitchen surfaces
• Helps maintain hygiene standards between scheduled deep cleans

This product is well suited to kitchens with high throughput — particularly those running fryers, chargrills, or solid-top ranges as part of daily service. For very large sites with multiple kitchen sections requiring frequent deep cleaning, higher-volume supply formats may be worth considering to reduce handling and reorder frequency.

If you are unsure whether this concentration level is right for your kitchen's cleaning regime, or want to discuss how it fits alongside your broader cleaning schedule, we are happy to help.
