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.

Frequently asked questions

How should Suma Star D1 be diluted for everyday pot wash use?

Dilution rates vary depending on the level of soiling and local water hardness, but Diversey typically recommend diluting to suit the task — lighter washing requires less product, while heavy grease and baked-on residue may need a slightly stronger solution. Following the manufacturer's dilution guidance will help you get the best economy from the concentrate.

Is Suma Star D1 suitable for use in a dishwasher or glasswasher?

No — Suma Star D1 is formulated for manual washing at the sink or pot wash station. Machine dishwashers and glasswashers require low-foam detergents specifically designed for those systems, and using a manual washing up liquid in a machine can cause excessive foaming and affect wash quality.

How long will a 20-litre container last in a typical commercial kitchen?

That depends heavily on your daily cover count, the nature of the washing up, and how accurately staff dilute the product. A busy pub kitchen or school canteen with high pot wash volumes will go through product faster than a smaller café. If you want a rough estimate based on your operation, the team can help work that out.
