Review on 🕊️ CoasterStone Victorian Lace Absorbent Stone Coasters, Set of 4 in White by Randy Montiel

They work very well as advertised and I would love them and buy more if they could be kept clean. However, they cannot and after a few months of ownership they look so awful that I take them out when there are guests in the house. Coasters absorb stains along with moisture that cannot be removed. I tried bleach as other commenters suggested. It partially worked the first time, then not anymore. If the coasters had been made a dark neutral color - perhaps brown or black - the stains would not have been visible. But since they're white it's hopeless, and all the other color options have silly prints that don't go with my decor. Disappointing.
