Expert Review and  Insights

In the world of commercial cleaning, you need products that deliver results without fuss, and  Diversey's Suma Grill D9 is a standout performer.

Charlotte Rayner – Commercial Cleaning Expert View Profile →

  • Pro: The foam clings brilliantly, making it highly effective on grill plates and  oven doors.
  • Con: It's a potent formula, so correct PPE and  good ventilation are absolutely essential.

Case Study: Real Business, Real Results

The Salty Squid, a popular fish and  chip shop in Whitby, was struggling with the daily chore of cleaning their high-capacity commercial fryers and  grills. The team found their previous cleaner required excessive scrubbing, adding significant time to their end-of-day cleanup routine.

"We switched to the Suma Grill D9 on a recommendation, and  the difference was immediate. The foam just melts the grease away. It's saved us so much time and  elbow grease, and  the equipment has never looked better."

David Chen – Owner

The switch resulted in their nightly cleaning routine being shortened by an average of 30 minutes, allowing staff to finish earlier and  reducing overall labour costs.

Installation and  Maintenance Guide

Using It Safely & Effectively

  • Always wear appropriate PPE, including alkali-resistant gloves and  eye/face protection.
  • Ensure the kitchen area is well-ventilated before, during, and  after use.
  • For best results on ovens, apply to warm (not hot) surfaces, typically between 60-80°C.
  • Spray directly onto the surface or equipment from a distance of about 25cm.
  • Leave the product to work for 5-30 minutes depending on the level of soiling.

Storage & Best Practice

  • Store bottles upright in a cool, dry, and  secure location away from direct sunlight.
  • Keep chemicals stored separately from food items and  food preparation areas.
  • Rinse the nozzle under a tap after use to prevent clogging and  ensure a good spray pattern next time.
  • Always rinse surfaces thoroughly with clean water after cleaning to remove any chemical residue.

Buying Guide: Choosing the Right Commercial Cleaner

Not sure which cleaner is right for the job? Here’s a quick guide to help you choose wisely.

Target the Soil

Identify the main problem. For heavily burnt-on food and  carbonised grease, a powerful alkali cleaner like Suma Grill D9 is essential. For general surface grease, a milder degreaser might suffice.

Consider the Surface

Always check that the cleaner is safe for the material you're cleaning. This cleaner is ideal for stainless steel but avoid using strong alkali solutions on aluminium, copper or other soft metals.

Concentrate vs. Ready-to-Use

Concentrated formulas offer better value for money but require correct dilution. Ready-to-use (RTU) products like this one offer maximum convenience and  consistent performance.

Application Method Matters

A foam spray is perfect for vertical surfaces and  deep equipment. A simple trigger spray is fine for flat tops, while a liquid for a soak tank is best for fryer baskets and  filters.

Prioritise Safety

Professional chemicals require respect. Always read the label, understand the PPE requirements, and  ensure a Safety Data Sheet (SDS) is available for your staff.

Frequently Asked Questions

Q: Can I use this on aluminium surfaces?

A: No, this is a powerful alkali cleaner and  is not suitable for aluminium, copper, or other soft metal surfaces. It is formulated for iron and  stainless steel.

Q: Does the oven need to be hot when I use it?

A: For best results, it should be applied to warm surfaces (around 60-80°C). Do not apply to surfaces hotter than 80°C.

Q: Do I need to rinse it off afterwards?

A: Yes, it is crucial to thoroughly rinse all food-contact surfaces with clean water after cleaning to remove any chemical residue.

Q: What does 'removes carbonised soil' actually mean?

A: It refers to the tough, black, burnt-on deposits that build up on ovens and  grills over time. This formula is specifically designed to break that down.

Q: Is the Diversey oven cleaner 6 pack more cost-effective?

A: Yes, buying in a case pack of six is more economical for busy commercial kitchens than purchasing single bottles, and  ensures you don't run out during a critical cleaning task.

Q: How does the foam help with cleaning?

A: The foam clings to surfaces, giving the active ingredients more time to penetrate and  dissolve the grease, especially on vertical walls and  oven doors where liquids would run off.

Q: Can I use this to clean my commercial deep fryer?

A: Yes, the Suma Grill D9 cleaner can be diluted for the 'boil out' cleaning of deep fryers. Always follow the specific dilution instructions on the packaging for this task.

Q: Does this product have a very strong chemical smell?

A: As a powerful cleaner, it does have a chemical odour. Using it in a well-ventilated area is strongly recommended for user comfort and  safety.

How Clinging Foam Beats Liquid Sprays

Ever sprayed a liquid cleaner onto an oven door and  watched it immediately run to the bottom, leaving the top grimy? That's the problem the Suma Grill D9's foam sprayer solves. Instead of a runny liquid, it dispenses a thick, active foam that clings to surfaces, including vertical walls and  even the 'ceiling' of your oven.

Think of it like trying to wash a window with water versus a proper window-cleaning foam. The water just sheets off, but the foam stays put, giving the powerful cleaning agents crucial extra time to work their magic dissolving grease and  carbon. This means less product waste, less need for reapplication, and  far less physical effort from you. The included extension lance also means you can apply this powerful foam to the back of a hot oven without putting yourself at risk.

Who Should Buy This?

  • Restaurants & Pubs: For deep cleaning commercial ovens and  grills after a busy service, keeping equipment in top condition.
  • Takeaways & Kebab Shops: To quickly dissolve tough, built-up grease on vertical rotisseries, grills, and  fryers.
  • Institutional Caterers: Ideal for maintaining hygiene standards in school, hospital, or care home kitchens with heavy-use equipment.
  • Event & Mobile Caterers: A reliable, powerful solution for keeping portable grills and  cooking equipment spotless on the go.
