Epic for high-performance and European cars with heavy brake dust issues. Deeper cleaning of grime with a sophisticated blend of specially selected degreasers and surfactants. Quick to use. Just spray on, wait a minute and quickly scrub, then hose off (pressure washer is strongly advised). Can be scrub-free if you're cleaning just brake dust. Spray on and pressure wash off. Proudly all Aussie-made and developed formula, great work from a great team of Aussie chemists!
