If your glass cooktop is covered in grease splatter, stuck-on food, or burnt residue that just won’t come off no matter how hard you scrub, you’re not alone. Glass cooktops look sleek and modern, but they show every mess and once buildup bakes on, it can feel impossible to remove. The good news? With the right approach and a little patience, you can restore your cooktop without damaging the surface.
The key is knowing when to start simple, when to level up your cleaner, and how to work through grease the right way. Grease doesn’t always come off in one pass, it often needs to be removed layer by layer. This guide walks through the best method for cleaning a glass cooktop safely, from everyday messes to heavy, burnt-on buildup.

Start by Degreasing the Cooktop Surface
The first step in cleaning any glass cooktop is degreasing. Over time, cooking oils, food splatter, and residue build up and harden on the surface. If the cooktop hasn’t been cleaned in a while, this step is especially important because grease often bonds in layers. Trying to scrub baked-on food without removing the grease underneath only makes the job harder.
A simple dish soap works extremely well for this step. Blue Dawn dish soap is a reliable option, but Dawn Powerwash is especially effective at cutting through stubborn grease. Spray or apply a generous layer across the entire cooktop and allow it to sit for a short time. This dwell time lets the soap break down the grease so you don’t have to scrub aggressively later.
Once the cleaner has had time to work, use a non-scratch scrubber to loosen the buildup. Warm water helps soften the scrubber and improves cleaning power without risking damage to the glass surface.
Use the Right Scrubber to Avoid Scratches
Choosing the correct scrubber is critical when cleaning a glass cooktop. Non-scratch options like a Scrub Mommy or Scour Daddy are ideal because they provide strong cleaning power without harming the surface. Softening the scrubber with warm water before use helps it glide smoothly while still lifting grease and grime effectively.
Scrub using gentle circular motions, focusing extra attention on the burner areas. These spots tend to collect the most grease and baked-on residue due to repeated heat exposure. Circular motions help evenly lift buildup rather than pushing it around or into scratches.
Avoid traditional green and yellow sponges entirely. While they may work well for dishes, they can scratch and permanently damage glass cooktops. Once scratches appear, they can’t be cleaned away and will dull the surface over time.
Rinse Thoroughly and Buff for a Streak-Free Finish
After scrubbing, it’s essential to remove all cleaner residue. Glass cooktops heat up during use, and leftover soap can bake onto the surface, creating stickiness and attracting even more grease. A damp microfiber towel works best to rinse the surface thoroughly without leaving lint behind.
Once the cooktop is fully rinsed, follow up with a clean, dry microfiber towel to dry and buff the surface. Glass cooktops behave much like mirrors, any streaks or residue will be visible once the light hits them. Buffing removes water spots and leaves the cooktop shiny and polished.
This method is ideal for everyday cleaning or cooktops that fall on the lighter end of the mess scale. Regular wipe-downs after each use prevent buildup and reduce the need for deep cleaning sessions.
When Dish Soap Isn’t Enough for Burnt-On Food
If the cooktop still has burnt-on food after degreasing, it’s time to use a dedicated glass cooktop cleaner. Products like Bar Keepers Friend Cooktop Cleaner or Scrub Daddy’s Stove and Cooktop Cleaner are designed to break down baked-on grease and residue without scratching the glass.
Apply a generous layer of the cleaner across the cooktop so it can work evenly. Many paste-style cleaners require a damp scrubber to activate properly. Letting the cleaner sit for one to two minutes or longer for heavy buildup helps loosen stubborn residue and minimizes the need for heavy pressure.
After the dwell time, scrub again using gentle circular motions, paying close attention to burners and heavily soiled areas. Grease removal often requires multiple passes, so don’t be discouraged if everything doesn’t come off the first time.
Clean Grease in Layers for the Best Results
One of the most important things to remember when cleaning a glass cooktop or any greasy kitchen surface is that grease often needs to be removed in layers. If residue remains after the first round of cleaning, it doesn’t mean the method failed. It simply means more buildup remains underneath.
Repeat the cleaning process as needed, reapplying cleaner and allowing it to sit before scrubbing again. Rushing or scrubbing too aggressively can cause damage, while patience produces better results with less effort.
Once satisfied, rinse thoroughly with a damp microfiber towel and finish by drying and buffing the surface until streak-free.
Using a Razor Blade Scraper for Extreme Buildup
For glass cooktops with severe burnt-on residue, typically those that haven’t been cleaned in a long time, a razor blade scraper can be a highly effective last resort. Used correctly, it removes buildup that cleaners can’t reach by sliding underneath hardened residue.
Always start with a brand-new blade. Old or rusted blades can scratch the glass. Before scraping, apply a cleaner to lubricate the surface never scrape a dry cooktop. Hold the blade at a low angle and work slowly, letting the blade do the work without applying excessive pressure.
This technique allows you to lift baked-on food completely off the surface rather than smearing it around. When finished, rinse and buff the cooktop again to restore shine.
Don’t Forget the Control Panel and Knobs
While cleaning the cooktop itself, it’s easy to overlook the back control panel and knobs, which often collect grease splatter. Removing the knobs and soaking them in warm, soapy water makes them much easier to clean.
Wipe down the control panel carefully, dry it completely, and reinstall the knobs once everything is clean. This small extra step makes a noticeable difference in how clean the entire range looks.
What Cleaning Can and Can’t Fix on Glass Cooktops
Glass cooktops naturally develop wear over time. Scratches and white haze, especially on frequently used burners, are common and can’t always be removed with cleaning. While proper cleaning helps improve appearance, wear marks are permanent.
Cookware choice also plays a role. Heavy cast iron pans or dirty pan bottoms can contribute to scratching and hazing if dragged across the surface. Keeping cookware clean and lifting rather than sliding pans helps protect the glass.
Clean Regularly to Avoid Deep Cleaning Altogether
The best way to keep a glass cooktop looking great is consistent maintenance. Wiping it down after every use prevents grease from baking on and eliminates the need for heavy scrubbing later.
A few minutes of regular care saves time, effort, and frustration and keeps your cooktop looking clean, clear, and polished for years to come.
