I love the concrete countertops in our house. I don’t have to worry about setting hot dishes on them, and the installers finished them silky smooth. They had started to develop rings and water stains, though. I used a mixture of baking soda and olive oil to rub them down, then added vinegar to the paste before wiping it off. I wiped the whole surface with a wet towel to make sure the vinegar was gone, then applied a sealing product used for butcher blocks. The sealant is made of natural oils and waxes and is food safe. The counter soaked up the mixture, so I did two applications, then buffed it with a dry towel. The counter looks new again, and I tested the water resistance by sprinkling it with water. The water beaded up and did not soak in.

So here is another Howard’s product I can recommend. But no, I’m not paid to do so!
