Be weary on how you clean it. If you do what I did which was use a stiff bristled white plastic scrub brush with mr clean clean freak the color from the brush will transfer to the grip tape and lighten the grip tape. I believe the batteries are water proof so if you ise a black stiff bristled brush and turn the battery vertical with the charge ports upright the use a spray bottle to mist plain water onto it you should be able to scrub downwards and the water will drip off.
I have been using a stiff bristle white brush on its own to get dirt off but it takes its toll on the color.
My new grip tape replacement is well worth the price. I think the entire kit for both the deck and kick plate are priced greatly. I am going to do some research on how to clean grip tape. There are probably better products out there designed to do so. Ill start with getting a black bristled brush.
Voro is great. Their customer service is great.
