Although a clay bar isn’t necessary, cleaning the vehicle surface with a clay bar prior to application will remove embedded surface contaminants such as tree sap, bug residue, overspray, rail dust and more. Removing these contaminants will enable the Factor 4 Synthetic Wax to form a stronger bond to your car’s finish. If you do clay the surface, this should be done prior to using the Factor 4 Cleansing Wash.

If you have heavy dirt on your car’s finish, we suggest pre-washing to clean the heavy dirt prior to beginning the Factor 4 Synthetic Wax System application process.

For best results and maximum durability be sure to use the Factor 4 Cleansing Wash. Factor 4 Synthetic Wax is a system and the wash are specially formulated to work with the wax. Using automatic car washes or DIY wash & wax will clean dirt and dust from your vehicle but does not contain the chemistry to bond with the Factor 4 Synthetic Wax.

The Factor 4 Deep Cleansing Wash solution plays a dual role in the process. First, it cleanses the surface, removing dirt and purging contaminants from the paint. Second, and most important, the Factor 4 Cleansing Wash creates a positive charge on the vehicle’s paint. This charge then fuses with the negative ions in the wax to create amazing shine and extreme durability.

By leaving Factor 4 Cleansing Wash on the surface for at least 15 minutes, it allows the positive ions contained in the wash to charge the vehicles surface. The charged surface will then crosslink with the negative ions of the Factor 4 Synthetic Wax creating an ultra-durable shine and long-lasting protection.
