Care of Plastic Laminate Counters
Plastic laminate counter resist scratches. However
they can be cut by knives or other sharp objects so slice
or chop on a cutting board, not on the counter. Never
hammer heavy items on the counter, as hard blows or heavy
objects dropped on the counter, can gouge it.
Avoid exposure to materials which can stain such as
tea, coffee, food dyes and indelible inks.
Plastic laminated countertops are made of melamine
plastic. They stand brief exposure to heat up to 275 F.
However longer exposure to temperatures of 140 F. and up
(the temperature of most hot water from water heaters)
can cause laminated layers to separate. Pans coming from
the oven or range-top at temperatures over 275 F. should
never be placed on the counter as they can soften and
burn the plastic. Keep an insulated hot pad or mat handy
to set such pans on. Also never put heated irons or
cigarettes on the laminated counter as they can burn
holes in it.
Strong acids and alkalis in such household cleaners
as rust removers, oven cleaners, metal cleaners, drain
and toilet bowl cleaners can etch, corrode, and
permanently discolor the laminated surface. Never put
such cleaners on plastic laminates. If some is spilled
accidentally, immediately wipe it off, and rinse
thoroughly.
