Yes, you can wash as you normally would if you like. You will find that you may not need to wash as frequently or with soap all the time, but if you want to then yes, of course, you can. DO NOT use Wash and wax soaps for prepping the surface, nor to clean the vehicle after applying TLC. If used before applying to prep the surface, TLC will not be able to bond correctly to the surface as it is a ceramic based product, and you may experience streaking. If used after applying TLC, due to TLC being so hydrophobic, it will shed the wax because The Last Coat is the real protection, and the wax may haze. So in short, use a basic car soap with no waxes or polymers, or merely straight rinse with clean, fresh water. The exception would be silica soap. Such as our own soap, The Last Soap. Otherwise we recommend pH neutral soaps. Finally, you'll find that a surface treated with The Last Coat will clean off easier with only water than an untreated surface.
