Jason DuncanI use grape cool aide. Just submerge the slab completely into a pitcher of Grape Cool Aide. Keep in mind that it MUST be Cool Aide brand mix with the big Cool Aide guy on the front of the package. Those other knock- off brands could deteriorate the plastic over time. Also you must use GRAPE. Cherry, Lime or any other flavor will stain the plastic! Good luck. Let me know how it turns out!
