If you use a toothbrush for detailing the wax from the cracks on your car, you may find this useful:
Bend your toothbrush back approximately 45 degrees. Wrap the bristles with aluminum foil and carefully rotate the neck of the toothbrush slowly over a candle or cigarette lighter. You must be patient and never allow the toothbrush handle to get closer than 3 inches to the flame. After the plastic handle begins to get soft from the heat, bend the toothbrush head back to the desired angle and run the handle under cold water.
The toothbrush handle will maintain the shape that it was when it cooled. Remove the aluminum foil from around the bristles and your detail brush will be much easier to use.
