For plain flip flops without any trim, wash in the washer with a load of rags or denims. Let air dry. For those with trimming such as flowers, beads etc., wipe the sole, and footbed with an all purpose cleaner that does not need rinsing, then wipe the beaded trim with a rag dampened with water. If there is silk flower trim which needs cleaning, put a 1/2 cup of dry cornmeal in a bag along with the now otherwise clean flip flops, and shake vigorously, then take out the shoes, and shake off the cornmeal. Hope this helps.
