Formica countertops are a type of laminate countertop. They mimic other types of countertops, like granite, but are not as expensive. Like any other countertop, Formica must be cleaned on a regular basis to prevent the build-up of dirt and stains. This must be done correctly, and you can use inexpensive cleaning supplies; many abrasive cleaners will damage the surface of a Formica counter.
Moisten a non-abrasive cloth so that it is damp, not soaking wet.
Add one drip of mild dish soap and wipe down the Formica countertops. Do this on a daily basis to keep the Formica clean.
Dry the Formica with a fresh non-abrasive cloth immediately after washing. According to The Natural Handyman, using a well-wrung-out wash cloth followed by a dry cloth will help prevent water from seeping through any seams in the counter and causing the substrate to swell.
If you find a stain on your Formica countertops, make a paste out of baking soda and water. Rub the mixture over the stain and then wipe the area clean with a damp cloth.
