Brake cleaner is one of the most widely used technical sprays in the workshop. It dissolves grease, oil, brake fluid, and dust from discs, pads, and drums without leaving residue. A greasy brake system doesn't brake correctly, and that is a safety issue.

Alongside brake cleaner, contact spray, penetrating oil, and other technical sprays fall under this category. Each has its own application: contact spray for electrical connections, penetrating oil for seized fasteners, silicone spray for rubber and moving parts.
