Expert Review and  Insights

In a busy kitchen, the quality of your washing up liquid is a non-negotiable. The Suma Star D1 is a product we see time and  again because it just works. It's an un-fussy, powerful degreaser that delivers the consistent results chefs need without any fancy marketing. It’s the definition of a reliable, professional cleaning staple.

Charlotte Rayner – Commercial Cleaning Expert View Profile →

  • Pro: Its concentration level offers exceptional value, noticeably reducing annual cleaning supply costs.
  • Con: The 20kg container is heavy and  requires careful handling or decanting.

Case Study: Real Business, Real Results

The team at 'The Harbour Inn' in Weymouth, Dorset, were struggling with their previous detergent, which required multiple washes to remove grease from their popular fish and  chip fryers and  pans. They switched to the Suma Star D1 to improve efficiency in their pot wash area.

"It's brilliant stuff. Everything comes out sparkling clean on the first wash, which has freed up one of our kitchen porters to help with prep during busy periods. We're not wasting time re-washing things anymore."

Robert Green – Head Chef

The switch resulted in a significant reduction in water usage and  cut down pot-washing time by an estimated 30% during peak hours.

Installation and  Maintenance Guide

Setting It Up

  • For safety, always store the main container on a low shelf or the floor in a cool, dry chemical storage area.
  • We recommend using a pelican pump (sold separately) to dispense the liquid cleanly and  without waste.
  • Decant a small amount into labelled, reusable squeezy bottles for easy access at the sink.
  • Always follow the dilution guide on the packaging for the most effective and  economical clean.

Keeping It Going

  • Ensure the cap on the main 20L container is tightly sealed after each use to prevent spills.
  • Routinely wash out the smaller dispenser bottles to prevent any residue build-up.
  • Monitor your stock levels – a busy kitchen gets through a lot, so don't get caught short!
  • Always have your staff wear gloves when handling the neat concentrate to protect their skin.

Buying Guide: Choosing the Right Washing Up Liquid

Not sure which detergent is right for your sink? Here’s a quick guide to help you pick the perfect product for your professional kitchen.

Concentrate vs. Ready-to-Use

Concentrates like this professional washing up liquid concentrate offer far better long-term value. You're not paying for water, and  a single container lasts much longer, saving money and  storage space.

Grease-Cutting Power

Domestic liquids often can't handle the baked-on grease found in commercial kitchens. Look for products specifically labelled for professional or commercial use for the best results.

Consider Hand Care

If your team spends hours at the sink, a formula that is effective yet not overly harsh is important. While gloves are always recommended, a quality formula is still a plus.

Scented or Unscented?

In a food environment, it's often best to choose a neutral or unscented detergent to avoid any risk of fragrance transferring to plates and  tainting your food's flavour.

The Right Pack Size

For a busy operation, a bulk commercial dishwashing detergent 20 litre container is ideal. It minimises the frequency of re-ordering and  ensures you're never caught without.

Why a Concentrated Formula is a Smarter Choice

Ever bought a big bottle of squash? You add a small splash to a glass and  top it up with water. A concentrated washing up liquid for kitchens works in exactly the same way. Instead of paying for a big bottle that's mostly water, you're getting a powerful, pure cleaning solution. You simply add a small amount to your sink of hot water to create the perfect cleaning mix. This means one 20-litre container of concentrate, like this Diversey FA464 washing up detergent, holds the cleaning power of many, many bottles of ready-to-use liquid. It saves you a huge amount on shipping costs, reduces your storage needs, and  is much better for the environment because you're throwing away far less plastic packaging. It’s the most economical and  efficient way to stock your pot wash station.
