The Jantex grillstone is one of those simple, no-fuss bits of kit that just works.

Charlotte Rayner – Commercial Cleaning Expert View Profile →

  • Pro: Extremely effective on tough, baked-on grease and  carbon deposits.
  • Con: The block wears down with use, so it requires eventual replacement.

Case Study: Real Business, Real Results

The team at 'The Burger Joint' in Manchester found their end-of-service griddle clean-down was taking far too long and  required harsh, smelly chemicals. They needed a faster, more effective, and  more pleasant solution for their staff.

"We switched to the Jantex grillstones and  the difference was immediate. What used to be a 20-minute scrub-down with strong fumes is now done in less than five. The griddle surface has never looked better, and  the team is much happier."

Ben Carter – Head Chef

The kitchen now saves over an hour of cleaning labour per day, a significant productivity boost that allows staff to finish sooner.

Installation and  Maintenance Guide

Using Your Grillstone

  • For best results, use on a warm (not scorching hot) griddle surface.
  • Apply a small amount of cooking oil to the griddle to help lubricate the process and  reduce dust.
  • Use firm, even strokes to scrub away burnt-on residue, working with the grain of the metal if visible.
  • Once clean, scrape away any residue and  wipe the griddle with a damp cloth, then re-season if required.

Looking After Your Block

  • After use, tap the block to remove loose debris or rinse under a tap.
  • Store it in a dry place to maintain its solid structure.
  • The block is a consumable item; replace it when it becomes too small to handle safely and  effectively.
  • Consider the optional handle (L403) for better leverage and  to keep hands away from the heat.

Buying Guide: Choosing the Right Grill Cleaning Tool

Not sure which cleaning tool is right for your setup? Here are a few things to think about.

Surface Type

Pumice stones are absolutely ideal for cast iron or steel flat top griddles. For grills with open grates, a stiff wire brush is a better companion tool.

Comfort and  Safety

Using a handle (like the L403 for this block) keeps hands safely away from the warm surface and  gives you much better leverage for tougher jobs.

Chemicals vs. Physical Cleaning

A professional grill cleaning block like this one massively reduces the need for harsh degreasing chemicals, creating a fume-free and  safer cleaning process.

Speed of Cleaning

For high-volume kitchens, the speed of a grillstone is a huge plus, drastically cutting down the time spent on the end-of-service clean-up.

Stocking Up

These are consumable items. If you run a busy kitchen, it’s always wise to buy them in multi-packs to make sure you never run out mid-clean.

Frequently Asked Questions

Q: Can I use this on a cold griddle?

A: It works, but it's much more effective on a warm surface as the heat helps to loosen the grease, making your job easier.

Q: Will this scratch my stainless steel griddle?

A: No, pumice is designed to clean effectively without scratching common griddle materials like steel or cast iron when used correctly.

Q: Do I need to use cleaning chemicals with it?

A: Not at all. The block's abrasive action is usually more than enough, especially when used with a little cooking oil on a warm surface.

Q: What is the optional handle for?

A: The compatible handle (L403) provides better grip, more cleaning power, and  keeps your hands safely away from the hot surface.

Q: How long does one block last?

A: This depends entirely on how often you use it and  how much build-up you're cleaning. A very busy kitchen may go through one every couple of weeks.

Q: Is it safe for food contact surfaces?

A: Yes. After cleaning with the block, the surface must be wiped down thoroughly with a clean, damp cloth to remove any pumice dust before you start cooking.

Q: Can I use it to clean my oven racks?

A: Yes, it's very effective for cleaning baked-on grease from oven racks and  trays, but test on a small area first if you're unsure.

Q: How should I clean the griddle after using the block?

A: Scrape off any loose debris and  pumice dust, then wipe the surface clean with a food-safe cloth and  hot water. Finally, re-season your griddle with oil as you normally would.

How Pumice Power Works for Your Kitchen

Ever wondered why a simple block of pumice is so good at cleaning? It’s all down to its gently abrasive nature. Think of it like a very fine, tough sponge. As you scrub a warm griddle, the porous stone crumbles just a tiny bit, constantly revealing a fresh surface that grabs onto burnt-on food and  grease particles without gouging the metal. It’s much safer for your griddle’s surface than a harsh wire brush and  far more effective than a simple scraper, which only takes off the top layer of grime. This griddle stone cleaner gets into every nook for a truly deep clean.

Who Should Buy This?

  • Busy Restaurants & Pubs: Perfect for the end-of-night deep clean on commercial flattop grills and  planchas.
  • Mobile Catering Vans: A compact and  powerful cleaning solution for keeping griddles pristine on the go.
  • Cafés & Bistros: Ideal for quickly cleaning smaller griddles used for all-day breakfast and  lunch services.
  • Takeaway Shops: Essential for fast-food kitchens that rely on consistently clean and  efficient grilling equipment.
