Plastic Melted on Surface
Thermoplastic or heat-softened plastics can be melted
and fused to surfaces, as when a plastic dish or film is
put on heated cooking surface by mistake. If the plastic
can be softened by heating to a low temperature, you may
be able to scrape it off with a smooth flat piece of
wood, or anything that will not itself melt when hot and
will not damage the surface. If irritating fumes are
produced as the plastic is heated, do not breathe them.
If opening windows and doors for ventilation does not
remove the fumes, it would be better to throw away the
damaged pan or oven rack than to injure your health by
breathing the fumes.
Sometimes you may be able to grind off the hardened
plastic residue with a power sander. Or take it to an
appliance or auto repair shop and see what they would
charge to do this.
