How Long Should Car Wax be Left on Before Removal?
You must take care to do car wax removal properly so that you do not damage the surface and finish of your vehicle. If you leave car wax on too long, it can harden. To prevent this, carefully follow the directions on the side of the bottle. Depending on the brand and product you have, you will probably only need to leave the wax on the car for between 5 and 15 minutes. Once the wax forms a haze on the car, you can wipe it down.
