As a commercial induction hob supplier, I’ve spent the last 8 years working with restaurants, caterers, and food service teams across North America, and one problem comes up in almost every follow-up call: “Why are there scratches on my hob, and how do I stop them?” Commercial Induction Hob
I get it—commercial kitchens are busy spaces. When service is ramping up for lunch or dinner, it’s easy to grab a metal pan off the counter, slide it across the hob to a burner, and call it a win. Those small moves add up fast, and before you know it, your once-sleek induction surface has a network of shallow scuffs and deep gouges. Worse, those scratches aren’t just an eyesore—they can trap food debris, breed bacteria, and even disrupt how your hob heats evenly, costing you in energy bills over time.
Let’s break this down the way we teach our customers at [Company Name]—no jargon, just practical, science-backed steps that actually work for commercial settings. I’m not here to sell you a overpriced “scratch-resistant polish” (those rarely do what they claim). I’m here to share what we’ve learned from thousands of installations and repairs, and how you can protect your investment for years.
First, let’s start with the basics: why induction hobs scratch differently than other cooktops. Unlike gas stoves, which have open flames and cast iron grates that sit above the surface, induction hobs work by creating a magnetic field that heats only the pan. The cooking surface itself is usually made of tempered glass-ceramic (that’s the heat-resistant stuff that can handle 1,500°F and up). But that material is durable, not indestructible. Scratches happen when harder materials (like metal, ceramic, or even sand and grit) come into contact with it with enough force. A 2021 study by the Food Service Equipment Suppliers Association (FSESA) found that 78% of commercial induction hob scratches come from three sources: improper pan use, dirty cookware, and careless cleaning. That’s good news—because those are all things you can control.
1. Choose the Right Pans for Your Induction Hob
This is the single biggest fix we recommend, and it’s free (or at least way cheaper than replacing a hob mid-contract). I’ve seen customers with $10,000 hobs ruin them with $20 aluminum pans that aren’t induction-compatible, or with cast iron pans that have rough, unseasoned bases. Here’s the science: glass-ceramic surfaces are softer than most metal pan bases that are marketed for commercial use. If your pan’s base has a jagged edge, rust spots, or loose bits of seasoning, sliding it across the hob is like dragging sandpaper across the surface.
Induction-compatible pans have a flat, smooth magnetic base. For commercial use, we recommend pans with a thickness of at least 3mm (for stock pots and fryers) and a polished, smooth bottom. Avoid any pan with a “ridged” or textured base—those ridges catch on the glass-ceramic and create micro-scratches every time you move it.
We also tell customers to avoid lifting pans when possible. It sounds counterintuitive—why lift a pan you’re using? But when you slide a 20lb stock pot across the hob, you’re not just moving it: the weight of the pot, plus any water or broth inside, creates friction. That friction is what causes deep, permanent scratches. Lifting it even an inch to move it eliminates that friction entirely. I’ve seen a customer in Chicago go from 12 new scratches a month to 0 just by switching to lifting pans instead of sliding.
One quick note: don’t buy “universal” induction pans from discount stores. Cheap pans often have thin bases that warp over time. A warped pan doesn’t sit flat on the hob—so the raised edges dig into the glass-ceramic every time you cook, creating uneven heat and scratches. We supply our customers with pan testing kits (for free) to check if their current pans are compatible: just put a magnet on the bottom. If it sticks, it’s induction-compatible and safe for the hob. If it doesn’t, it’s time to upgrade.
2. Keep Your Hob (and Pans) Clean—Every Shift
Grit, food debris, and even small pieces of metal or glass from utensils are your hob’s worst enemy. Imagine this: after service, you leave a pile of crumbs and burnt food on the hob. When the next shift starts, a line cook grabs a metal spatula to scrape the debris off. That spatula has tiny pieces of metal from previous uses, and that grit acts like sandpaper between the spatula and the hob. By the end of the week, you’ve got a dozen scratches you didn’t notice.
The FSESA study also found that 42% of commercial hob scratches come from dirty surfaces. Here’s our step-by-step cleaning routine that works for every commercial kitchen, without damaging the glass-ceramic:
- Clean between every shift: Don’t wait until the end of the day. After you turn off the hob, let it cool for 5 minutes (never clean a hot surface—that’s a quick way to crack the glass or burn yourself). Use a plastic or nylon scraper (never metal) to remove food debris. We supply food-grade plastic scrapers to all our customers for this exact reason. Metal scrapers are sharp and can nick the surface, even if you’re careful.
- Wipe with a non-abrasive cleaner: Avoid anything with bleach, ammonia, or scouring pads. These chemicals can etch the glass-ceramic, making it more prone to scratches over time. Instead, use a mild, pH-neutral cleaner made specifically for induction hobs. We stock these for our customers at wholesale prices, but you can also use a mix of warm water and a drop of dish soap. Wipe with a soft microfiber cloth—abrasive sponges (like Scotch-Brite) leave tiny, abrasive fibers on the surface that can create scratches when you cook.
- Clean your pans too: A lot of people forget that their pans can transfer scratches. When you wash a cast iron pan with a steel wool scrubber, tiny metal particles get stuck in the texture. Those particles then rub off onto the hob every time you slide the pan. We recommend washing induction pans with a soft sponge, and re-seasoning cast iron pans every 2 weeks to keep their bases smooth.
I once had a customer in a New York restaurant who tried using a steel wool pad to clean their fryer pans. Within a month, their hob had scratches across two burners. When we switched them to soft sponges and regular re-seasoning, the scratches stopped. It’s that simple—small habits make a huge difference.
3. Use Protective Mats for Heavy or Delicate Tasks
For busy commercial kitchens, heavy duty mats are a game-changer for protecting the hob. We recommend two types: non-slip silicone mats for under large stock pots, and felt pads for small items like spatula rest or mixing bowls.
Silicone mats are heat-resistant (up to 500°F, which is more than enough for most commercial cooking) and create a barrier between the pan and the hob. They also prevent the pan from sliding, so you don’t have to worry about accidental movement during busy service. For large items like steam pots or rice cookers, a ¼-inch thick silicone mat eliminates the friction that causes scratches.
Felt pads are smaller, but they’re essential for items that sit on the hob between uses—like spatula holders, ladles, or even small bowls of ingredients. I’ve seen line cooks set a metal ladle directly on the hob between dishes, and the constant back-and-forth movement of the ladle creates tiny scratches. Adding a 2-inch felt pad under each item stops that.
One thing to watch out for: never use rubber mats. Rubber can melt on hot hobs, leaving a sticky residue that’s hard to remove, and the residue can attract dirt that leads to scratches. Stick to food-grade silicone and felt—we only supply these types of mats to our customers, and we’ve tested them for 2 years without any issues.
4. What to Avoid At All Costs (These Are the Big No-Nos)
After working with so many kitchens, there are a few mistakes that I see people make over and over, and they almost always lead to deep, irreversible scratches. Let me spell them out clearly:
- Don’t slide metal utensils across the hob: Metal spatulas, tongs, and turners are sharp. Even if you’re just scraping food off a pan, sliding the utensil along the hob can nick the surface. If you need to scrape the hob, use a plastic scraper, not a metal one.
- Don’t drag heavy items: We’ve had customers try to move a 50lb gas canister across the hob (don’t ask—someone made a mistake when delivering supplies). The result was a 6-inch deep scratch that couldn’t be repaired. Any item over 10lb should be lifted, not slid.
- Don’t use abrasive cleaners or tools: Scouring pads, steel wool, oven cleaners, and bleach-based products are all off-limits. They scratch the surface and can damage the electrical components underneath, which will lead to costly repairs.
- Don’t ignore small scratches: A tiny scratch might seem harmless, but it can trap food and bacteria, and over time, it will get deeper as more dirt and grit get stuck in it. If you notice a new scratch, clean it thoroughly and make sure your pans and tools aren’t contributing to the problem.
5. If You Already Have Scratches—Can You Fix Them?
Let’s be honest: no DIY kit can completely remove a deep scratch from a glass-ceramic induction hob. The material is too hard for home products to buff out permanently. But for small, shallow scuffs, you can use a non-abrasive, food-grade hob polish. We supply a professional-grade polish to our customers that works by filling in the micro-scratches, making them less noticeable, and creating a smooth layer that resists future scratches.
If you have deep scratches (more than 1/32 of an inch deep), the only real fix is to replace the surface, which is why prevention is so important. At [Company Name], we offer free annual inspections for our customers—our technicians check the hob for scratches, test the pans, and help adjust cleaning routines to keep small problems from getting big ones.
At the end of the day, a commercial induction hob is a big investment—for most kitchens, it’s one of the top 3 purchases after refrigeration and exhaust systems. Scratches don’t just ruin the look; they can shorten the lifespan of the hob by up to 50% if left unaddressed. That’s why we make it a priority to teach our customers not just how to install the hob, but how to care for it.
