We have an awesome kitchen set siilar to the one pictured above that we got from my friend’s daughter. It’s a wood set and the table top is made of square tiles. I always wondered what the best thing to use to clean it was, since I knew I shouldn’t use abrasives. I recently found a possible solution completely by accident. Laundry detergent. I accidentally got some on the table and the table grout lines came out super clean and bright white.
