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.

Frequently asked questions

How do I choose the right dilution ratio for D9?

Diversey recommend varying the dilution depending on the level of soiling — a weaker dilution is generally sufficient for regular maintenance cleans after each service, while a stronger concentration is more appropriate for periodic deep cleans where carbonised residue has built up over time. Always follow the product label guidance for contact times and rinsing, as these vary with dilution strength.

Is D9 safe to use on all commercial oven and grill surfaces?

D9 is suitable for most commercial cooking equipment surfaces, but care should be taken with aluminium components, which can be sensitive to strong alkalis. If your equipment includes aluminium shelving, trays, or internal parts, check compatibility before use or contact us for guidance on the most appropriate product for your kit.

How much product is a high-volume kitchen likely to use, and is this pack size sufficient?

Usage varies considerably depending on the number of units being cleaned, cleaning frequency, and dilution ratios applied. For a busy kitchen cleaning multiple grills and ovens daily, a 5-litre container may last anywhere from a few weeks to a couple of months. The twin-pack format helps reduce the risk of running out mid-period, but if you are unsure whether this pack size suits your throughput, we can help you estimate usage based on your operation.
