  • Performance Plus: Genuinely effective on stubborn grease and  food residue without harsh chemicals.
  • Professional Use Only: Remember, this is a concentrate and  requires careful handling and  proper dosing.

Case Study: Real Business, Real Results

The Harbour View Bistro in Penzance, Cornwall, was struggling with the effects of hard water, leading to spotty glassware and  frequent descaling of their pass-through dishwasher. They needed a more effective, all-in-one solution.

"We were spending a fortune on descaler for the machine and  still getting streaky glasses. Switching to Suma Nova L6 has sorted both problems at once. The results are fantastic, and  our team appreciates using a greener product."

Mark Jennings – Head Chef

The switch has eliminated the need for a separate monthly descaler, saving approximately £30 a month, and  reduced re-washes by over 15% due to a superior first-time clean.

Installation and  Maintenance Guide

Setting It Up

  • This product is designed for automatic dosing systems. Ensure the feed tube is securely placed in the container.
  • Always wear appropriate PPE, such as gloves and  eye protection, when changing containers.
  • Clearly label the dosing line to avoid any mix-ups with other chemicals like rinse aid.
  • Ensure staff are briefed on the correct handling procedures for a concentrated chemical.

Keeping It Going

  • Store in a cool, dry, and  well-ventilated area, away from direct sunlight and  foodstuffs.
  • Keep the cap tightly sealed on the container when not in use to maintain the product's integrity.
  • Periodically check the dosing pump and  tubes for any crystallisation or blockages.
  • Order your next bulk commercial dishwasher detergent before you run out to ensure continuous operation.

Buying Guide: Choosing the Right Detergent

Not sure which chemical is right for your machine? Here are a few things to consider to get the perfect wash every time.

Water Hardness

If you're in a hard water area, you need a detergent with built-in limescale control, like this one, to protect your machine and  prevent chalky residue on your wares.

Dosing System

This is a concentrate designed for machines with automatic dosing pumps. This ensures accuracy, safety, and  ultimate economy, delivering the perfect amount for every cycle.

Eco-Credentials

Look for trusted certifications like the Nordic Swan. They are independent proof that the product is effective while meeting high environmental and  safety standards.

Cost-In-Use

Don't just look at the price per bottle. A high-quality concentrate offers a much lower cost per wash, saving you a significant amount of money in the long run.

Your Wares

If you wash a mix of delicate glassware and  heavily soiled pots and  pans, you need a versatile and  powerful formula that can handle both with ease.

Frequently Asked Questions

Q: Is this detergent suitable for all commercial dishwashers?

A: Yes, it's formulated for all professional and  commercial dishwashers equipped with an automatic liquid dosing system.

Q: Does it work well in hard water areas?

A: Absolutely. It contains powerful sequestrants that actively control limescale build-up, making it ideal for hard water conditions.

Q: Is this a detergent and  rinse aid in one?

A: No, this is a dedicated, high-performance detergent. For best results, including rapid drying and  a perfect shine, we recommend using it with a separate rinse aid.

Q: What does 'concentrated' really mean for my business?

A: It means the formula is undiluted, so you use a much smaller amount per wash cycle. This makes it highly economical and  reduces packaging waste and  storage needs.

Q: Can I use this for manually washing pots and  pans?

A: No, this product is specifically formulated for the high temperatures and  pressures of automatic dishwashing machines and  is not suitable for washing by hand.

Q: Why is this item non-returnable?

A: Due to its classification as a hazardous chemical for transport, regulations prevent us from accepting returns on this item for safety reasons.

Q: Do my staff need to wear PPE when handling it?

A: Yes. As with all professional-grade chemical concentrates, we strongly recommend wearing protective gloves and  eyewear when connecting or disconnecting the container.

Q: Is it safe for use on aluminium?

A: This is a powerful alkaline detergent, which is not recommended for use on soft metals like aluminium, copper, or brass as it may cause discolouration.

Tom P. – The Gilded Spoon, Bath

"Our glassware has never been shinier. It really helps with the hard water we have here in the Peak District. Highly recommend."

Chloe Davies – Hotel Manager, Buxton
