When burn stains appear on glass hobs, they leave behind unsightly discolourations. Burn marks need to be removed carefully because glass hobs scratch easily. Harsh abrasives can cause permanent damage to hobs. Removing burn stains immediately will prevent them from ruining the appearance of your hob, and it will also help extend the life of your hob.
Allow the hob to cool completely before you attempt to remove the stain.
Remove a thick burnt area with a dull butter knife. Scrape carefully so that you do not scratch the surface. Scrape until the area remains smooth. If you have difficulty scraping the burn stain off, moisten it with distilled vinegar and allow it to sit for 20 minutes.
Add 2 tsp of baking soda to a bowl. Slowly add water and stir until a thick paste forms.
Rub the baking soda paste over the burn area. Allow it to sit on the stain for 10 to 15 minutes.
Scrub the burn stain with a sponge. Apply the baking soda paste again if it does not remove the stain. Add two to three drops of lemon juice over the paste to help dissolve the stain.
Wipe the baking soda off with a damp washcloth. If you continue to have difficulty removing the stain, purchase a commercial stain remover designed for ceramic or glass hobs. Follow the instructions on the cleaner to ensure that you apply it properly.
