I just moved into a new apartment. The one that lived there before probably didn’t keep Kashrus. How can I Kasher formica counters?
Kashering a countertop:
- Preparing the countertop: The countertop must be thoroughly cleaned. if any dirt is on the countertop it cannot be Koshered (generally speaking). A mere discoloration however is fine. (feel the discoloration with your hand to ascertain if it is just a discoloration or if there is actual dirt). Do no use items to be kashered or the kashering pot with hot food for 24 hours in advance. The countertop must be completely dry before koshering.
- Pour boiling water over entire countertop and move a hot stone or iron over counter top. Rinse counter with cold water.
- Pour boiling water (no stone). Best to do so three times.
- Do not place hot food or pots directly on counter.
