TW20 Truck Wash is a non-toxic, non-caustic, biodegradable heavy duty detergent with a balanced pH and is highly effective in removing dirt, mud, road grime, oil and exhaust soot. It may safely be used to clean paintwork, chrome, rubber, windscreens, fibreglass, aluminium, tarpaulins, vinyl and most washable surfaces. It will not affect paint and, being free-rinsing, will not cause streaking.
