EASY TO CLEAN - Worried about spills, creases or dirt? That's not a problem for our placemats. The seagrass is covered with a fine layer of transparent organic paint, allowing the mats to be easily cleaned with a damp cloth or sponge. You can also wash the mats by soaking them in lukewarm water, just make sure to hang them dry before next use as seagrass may be prone to mold if stored in a high-moisture environment
