Dissolve is an odourless cold degreaser (barely smells at all) that effectively breaks down asphalt, oil, and other petroleum-based grime. It can be applied to both wet and dry surfaces.
Of course, it's perfect for engine washing and the like. Remember, the product should stay on the surface longer in cold temperatures. For best results, Extract should also be used on top of Dissolve.
You'll also need Extract, meaning just one type of degreaser won't cut it year-round.
