General rules for tarmac
Absorb vehicle fluids immediately. Oil and solvent can dissolve bitumen binder, so use only cool mild detergent or a labelled tarmac-compatible remover and stop if the surface softens.
Check the label
Check whether the surface is asphalt or tar-bound, recently laid, sealed, softened or already shedding aggregate.

Tarmac can be damaged by a cleaner that is harmless on a different material. Identify the exact fibre, coating, finish, care code and construction before treating a stain.
Use the least aggressive route
Absorb vehicle fluids immediately. Oil and solvent can dissolve bitumen binder, so use only cool mild detergent or a labelled tarmac-compatible remover and stop if the surface softens.
Judge only when dry
A remaining patch may be residue, dye transfer, finish change or material damage. Stop if a hidden test changes colour, gloss, texture, shape or adhesion, and use a specialist when the care label or finish cannot be established.
