Glass Science has proved its practical innovation once again with the release of Ultra Clean - Windshield Washer Super Concentrate. Ultra Clean is a unique windshield wash concentrate which allows drivers to safely and effectively wash their windscreens while they are driving. The super concentrate formula is diluted with water and added to the windscreen wash reservoir, ready to be used the next time your windscreen needs cleaning while you’re on the road. It removes dirt, surface film, dust and other contaminants leaving your windshield streak-free, clean and clear. Ultra Clean can be used all year round, including wintertime in climates which drop below zero. One bottle of 946ml concentrate will make up to 60 litres of washer fluid. Ultra Clean will make sure you can always keep your glass clean and clear.
