We have a typical, very popular ceramic cooktop stove. Dear wife made blackberry jam and it boiled over. The material stuck to the cooking surface is like concrete.
Any tips on removing this gunk? One would think a razor blade would work but I may have read that the cooktop could be damaged by a razor blade if one isn’t careful. We’ve purchased multiple “tough residue” cleaning products to no avail.
We had a similar problem* and Googled for solutions, which were many. The one that worked for us was a heavy sprinkle of baking soda and a spray bottle of vinegar to produce that wonderful 3rd-grade-science-experiment fizz. Liberally douse and allow the fizz to subside, then wait another 15-20 minutes before using a plastic utensil with a flat edge to scrape off. Was very surprised how well this worked.
*Don’t ask, but somehow one of the burners turned itself on while a small rubber-backed throw rug was atop. No one noticed until there was smoke and an awful smell. What a melted mess. And don’t ask why there was a rug on top of the stove.
I have a flat top too and I would try boiling water first. Then I would scrape with the back of a spatula (turn the spatula over). I have a thin metal one that is great for scraping off stuck on stuff. Have had this stove and spatula for at least 12 years and this is my go to method, plus a little soapy water. Helps that our stove is black, but it’s been a great way to clean it. I don’t use any special products, but they do make some specifically like the Cerama Bryte.
Long story but a piece I want to keep (sort of like a larger nightstand) was stored in a closed up musty area for most of Covid. It is not really dirty, no mold - it’s in great physical shape - but musty smelling! I squirted it with the hose today and had it outside drying out - but then it started raining.
It has a drawer and I put one of the charcoal beanbags in that but it won’t help with the rest of the piece. Maybe jist time airing out will help - but thought I’d ask for suggestions
-Dryer sheets
-Coffee grounds
-Bowls of vinegar (or wipe with vinegar dampened cloth per Martha Stewart)
-Baking soda sprinkled and left overnight then vacuumed
Try spraying an inconspicuous spot with vinegar and see how it reacts to that. Vinegar is good for mold and mildew. I know you said it’s not mildewy, but it may help. The vinegar smell usually dissipates. Worth a try on a small area.
