ValetPRO Citrus Pre-Wash

Sourced from Ultimate Finish, this adds a step to car cleaning as it is designed to be used prior to shampooing. Dilution instructions could be clearer, but it certainly loosened our road grime, making it easy for the lance to blast away. There was little foaming and it ran off quicker than most, but it worked. Usefully, it can also be used on fabric and plastics.
