Carlack Excellence Wheel & Rim Gel is the first wheel cleaner to combine iron-dissolving chemistry with a wheel protectant. In a single step, it removes stubborn brake dust and grime, and lays down a microscopic layer of dirt-repelling polymers. The main ingredient in Carlack Excellence Wheel & Rim Gel is a powerful neutralised acid salt. This reduces iron particles into a soluble form, making them easy to rinse off with a stream of water. As a result, Carlack Excellence Wheel & Rim Gel is safer and less chemically aggressive than traditional acid-based wheel cleaners, but equally as effective in terms of cleaning power. Its gel-like composition means it clings to treated surfaces with ease, extending its working time and minimising the need for agitation in all but the most extreme cases. Its non-aggressive formula is safe for all wheel types (including anodised, chrome plated and bare polished metal finishes) and regular use will build up a layer of protection on your wheels and make future cleaning even easier.
