It’s a great essential for the garage. It evaporates almost instantly and doesn't leave any residue behind, which is exactly what you want when you're trying to get rid of that annoying brake squeal.
It does a solid job cutting through brake dust and any road grime or oil that ends up on the rotors. Since it's safe on carbon and paint, you don't have to worry about overspray ruining the finish on the wheels or the frame. It definitely makes the brakes feel a bit sharper after a quick clean.
