It's a specific product that’s been developed with one goal in mind. And CarPlan’s no-nonsense entry is easily the best tar remover here. You simply spray the fluid on to the stain, work it in and remove it with a sponge, and you’ll quickly have a clean, tar-free panel. Performance on other marks was less impressive, and dried-on overspray was a nightmare to remove.
