I was grilling and just about to take the steaks off when a gust of wind came and blew a plastic bag on to the outside of the ss hood as I was opening it. I grabbed it quickly but some melted on.
After the grill had cooled I did get some off by wetting with soap and water and peeling. A large spot still remains (as I was running out of daylight). Any suggestions on the best way to remove the rest? Thanks btw, nice info here.
poe ...
There are no solvents that effectively dissolve low density polyethylene [the most probable plastic used in the bag] at ambient temperatures and the solvents that are effective at higher temperatures are also flammable [and toxic].
Low density polyethylene [LDPE] has a melting range between 220F-240F ... so you might want to try and heat up your grill, and see if the LDPE can be removed once melted [I'd try using a non abrasive material like a paper towel].
As a last option, I'd suggest that you try Barkeeper's Friend ... it contains a mild abrasive which should mechanically remove the LDPE from the SS without doing damage.
