I DO NOT RECOMMEND USING WINDEX!!! OR PAPER TOWELS!!! WINDEX can eat away at the adhesive on the griptape, causing it to peel! Use water, and dip the toothbrush in it lightly, and scrub in small sections! And don't dry with paper towels because there's a chance of some shreds of towel getting caught in the tape, and its a bitch to get out!
