Q: When should HD® Advanced Decontamination Clay Bar be used? A: Because your vehicle is constantly under attack by the harsh environment, feel free to clay as often as you’d like.

Frequency of claying will depend on your vehicle’s environmental exposure, amount your vehicle is driven and how often it is washed. The quickest and best way to determine if your vehicle can benefit from claying is actually very easy. Simply insert your hand into a plastic bag and rub it gently across your car’s finish. If you can feel roughness or tiny “bumps” then it’s time for decontamination. Q: How does HD® Advanced Decontamination Clay Bar work? A: Think of clay as a large car eraser that gently rubs away bonded contaminants from your vehicle’s surface. The cleaner your car’s paint is, the more it will shine. When used with HD Touch surface and clay bar lubricant, your clay bar will effortlessly glide across the surface picking up these stubborn pollutants and depositing them safely into your clay bar. Simply kneed or fold the dirty side of your clay bar into itself to bring about a fresh new layer of clay. Simple apply more lubricant to your clay bar and surface and then repeat. It’s that simple! Professional Quick Clay Tip: Because HD® Advanced Decontamination Clay Bar comes in such an ample portion, take your clay bar and separate it into 3 or 4 pieces. This will allow you to extend the life of your purchase in case you accidentally drop it. Remember: if you drop your clay on the ground, it must be discarded. Never reuse your dropped clay bar on your paint or this could cause severe marring to the surface.
