We found this one sort of by accident. One of our employees has a Rabobank edition tcr complete w/ white bar tape. - Mechanics run in fear when they see a white road bike roll in..Cause it's just soo fun to try to clean them, and keep the tape clean.
One day our employee was cruising around the shop looking for the bike cleaner, and found a tub of GOJO wipes. These are shop wipes with a citrus scent, and have a rough texture to them. She gave them a try, and sure enough they work GREAT!
And in fact we have a couple of ladies come in just to have us clean their bar tape.
Oh and to keep clean tape clean, we wrap the bar's in Press and Seal saran wrap. Works like a charm!
