This long-time proven cleaner has been around for many years and here is an example how this wonderful solution was used to superbly whiten a single pedestrian crossing strip to almost better than original appearance. Note the comparison to the uncleaned strips that have been subject to continous dirt and soil from motor vehicles, dirty shoes and other common discolorating roadway surface evils.
