Most tar removers run straight down the panel and off the sill within a minute, which is why they never get long enough on the contamination to do the job properly. Vasco Prewash holds its position on a vertical panel for as long as you leave it, and that dwell time is what does the work.\u003c\/p\u003e\n\u003cp\u003eIt has a following among working detailers in Ireland and the UK for a reason: it is a non-solvent cold degreaser, so it lifts tar, asphalt, road salt and greasy road film without the harsh solvent attack that makes people nervous around trim, lights and freshly painted panels. Spray it on a dry car, leave it while you get on with something else, rinse from the bottom up. No mitt, no clay, no rubbing tar across your clearcoat.\u003c\/p\u003e\n\u003cp\u003eWe stock Vasco Prewash in 1L for the enthusiast and 5L for anyone washing cars every week.

They sit in the bottom quarter of every panel after a resurfaced road or a wet motorway run, and the usual fix is a solvent and a lot of rubbing on paint you have just spent an hour correcting.
