A tyre mark on your concrete driveway is an unsightly blemish. Car or bicycle tyres can leave marks just from sitting in the hot sun. Accidental tyre spins call leave marks as well. Once ingrained into the concrete pores these marks can be difficult to remove. All tyres are made with petroleum-based chemicals, which means they have an oily composition. This composition will resist regular soap and water.

Apply a coating of degreaser solution thick enough to completely cover the tyre marks. Scrub the solution in with your brush to penetrate and loosen the tyre rubber.
Allow the degreaser to sit on the tyre marks for several minutes. This will allow the chemicals in the degreaser to actively work to loosen and dissolve the oil and the rubber from the tyre marks.
Attach your garden hose to the pressure washer and turn on the water valve. Start your pressure washer by pulling the starter rope, if it is petrol powered, or plug it in and flip the "on" switch if it is electrically powered.
Pick up the wand, which is attached to the washer with a hose, and pull the trigger to release a stream of pressurised water. Pressure wash the solution-covered area with a 5 cm (2 inch) stream of water, which is adjustable at the nozzle tip. Play the stream back and forth across the marks until they are gone. If results are not satisfactory, cover the area with another brushing of degreaser and pressure wash the area again.
Tips and warnings
- Scrubbing lighter coloured tyre marks with a heavy duty cleaner like TSP may remove them, but if the marks are dark black, only the high pressure generated by a pressure washer will clean them completely.
- Always keep the pressurised stream of water moving to keep from eroding away the concrete that you are washing.
