One time I used a sheet of paper and an iron. Lay the sheet of paper over it and take a hot iron and put over the paper. It will melt the plastic and it will stick to the paper. I am not sure about melted plastic, but I've removed dried wax from fabric by placing a brown paper bag (usually a lunch bag) on top of the wax (or plastic in your case) and running a medium heat iron over the bag. The wax came off, so maybe it will work for melted plastic.
To remove melted plastic from glass allow the melted plastic and glass to completely cool. Wet a cloth with ammonia, wring it out so that it is not dripping, but still very wet. Place it over the plastic and let it sit for at least 60 minutes. Remove the cloth and use a plastic scraper to remove the melted plastic.
Melted plastic is generally non-toxic and usually a pain to remove. It is generally disposed of as trash, as it cannot really be re-used. If it's hot, it is hazardous as it can burn you and tends to stick to skin and materials. In that light, it is dangerous. Melted plastic is the material used in injection molding. That melted plastic is not "bad" as it is being used for a purpose (the manufacture of goods).
To remove a melted plastic bag from the bottom of a car, let the car cool down a bit, but not completely. Take a metal knife and chip the plastic gobs off.
Most plastic bottles will be melted or burned by fire!
Ammonia is not a cleaner we'd choose to remove plastic from surfaces. It (ammonia) won't dissolve or "melt" the plastic, so it is ineffective in removing melted plastic from surfaces.
Plastic plates are made of melted plastic pellets. The melted plastic is forced into a mold, where it forms the plate and cools. Another material used for plastic plates is called Melmac. This process is basically the same, but the product is a resin called melamine.
I believe in most cases it is just a good general idea to remove the melted plastic all together, just to be safe.
WD 40 and a razor blade.
why is there melted plastic in the first place?
yes as it is plastic
To remove melted plastic from a wood floor, you will need an iron and brown paper sacks or brown craft paper. Lay the craft paper over the plastic. Apply the hot iron to the paper and apply pressure just until the plastic becomes soft. Once the plastic is soft, peel it off the wood floor.
Try a window scraper (razor blade) type.
