Public car washes — especially those with soft-touch equipment — should be avoided at all costs. These drive-thru services often harbor abrasive residue from previous vehicles, which can be dragged across your paint, causing scratches and compromising your ceramic coating. Additionally, the harsh chemicals used in these washes can be corrosive, prematurely degrading your coating and even voiding its warranty. Protect your investment by opting for safer, hand-wash methods designed to preserve your vehicle’s finish and coating integrity.
