Today was maintenance day.
The granite in the kitchen had to receive two treatments of sealer. Once that was dry a coat of car wax. They now shine like glass. Easy. Takes a little time, but easy.
The Korian was not so easy. There were dull spots where the previous finish has peeled up and the countertop looked scarred. We were scared it was scarred. (Just a little play on words). I found the remedy for this to be a couple coats of quick drying glossy floor wax. Once that was dry, I then applied a car wax. Shines like new. Actually it shines better than new. (Breaking my arm patting myself on the back now).
These countertops should be done every six months or so. Unfortunately they don't get done that often. But if they are kept up they wipe off easier and bacteria is not able to penetrate. Plus they will look great.
Nowadays they sell the granite pre-sealed. That sealer should last up to ten years. So, if you are installing granite, ask for that.
