Tar, bitumen and sticky road film cling like concrete. Koch Chemie Teerwasche A (TEA) is a solvent-based special cleaner built to dissolve them fast, without heavy scrubbing.
Koch Chemie Teerwasche A (TEA) is a dedicated tar and bitumen remover crafted for serious clean-up work. Unlike general cleaners, this solvent-based formulation is built specifically to dissolve sticky, oily contaminants that traditional soaps can’t touch. Whether you're working on cars, caravans, farm machinery or construction vehicles, TEA breaks down tar, road film, adhesive residue and bitumen with precision.
It works exclusively on solvent‑resistant surfaces like paint, metal, aluminium, glass, and plastics rated to withstand solvents, and is free from halogenated hydrocarbons, making it safer than many harsher alternatives. The product remains user‑friendly: spray, dwell, agitate gently if needed, then rinse or wipe clean. You’ll see the contaminant dissolve and lift away without leaving residue or haze behind.
TEA is used undiluted, so there’s no mixing: apply it, let it work and rinse it off. And since it’s made for tough jobs, many detailers and fleet operators keep a bottle on hand when dealing with transport fleets, heavy equipment or tar-laden roads.
Features:
- Highly effective on tar and bitumen: Dissolves road film, asphalt, adhesive stains
- Safe on solvent-resistant surfaces: Ideal for paint, glass, metals and plastics rated for solvents
- No halogenated hydrocarbons: Cleaner alternative to older solvent removers
