Can it stain my driveway?
As Wheely Clean is water soluble, it washes away with water, so make sure you rinse the area well around your wheels when done. Most surfaces have no issues, but we have seen some slight marks on old, unsealed concrete if not washed away and left to dry, but they can be easily scrubbed off. If you have any concerns you can always wet the area around the wheels before use.
Interestingly, you will notice the colour reaction also happening on the ground after rinsing the area down the first time. This is as the brake dust is washed off the wheel and the chemical reaction continues after getting cleaned off the wheel. So don't be scared to give a second rinse to the wheel area 5 minutes later, or wash the car straight after cleaning the wheels (which is what we do).
