Many car owners wonder if ceramic coatings, known for their durability and resistance, can be harmed by regular car wash soap, even dish soap. This concern often arises from the understanding that ceramic coatings are designed to be chemically resistant and longer-lasting than traditional waxes or sealants.
However, the selection of car wash soap does matter, even for vehicles protected with ceramic coatings. Soaps that include added “protection,” such as waxes or gloss enhancers, can sometimes interfere with the coating’s intended performance. These additives may temporarily mask the hydrophobic properties of the ceramic coating, affecting how water beads and sheds off the surface.
For routine washing, it’s generally advised to use a pH-neutral car wash soap that is free of extra protectants. These “protection-free” soaps are formulated to clean effectively without leaving behind residues that could diminish the ceramic coating’s performance. Using such soaps ensures that the coating’s inherent properties are maintained, allowing it to perform as intended.
In situations where a vehicle is frequently exposed to harsh conditions or heavy road grime, a higher pH soap might be occasionally necessary. This type of soap can be used for a decon wash to remove more stubborn contaminants that a pH-neutral soap alone might not fully eliminate. The decision to use a higher pH soap should be based on individual driving conditions and the level of environmental exposure the vehicle endures. Regular use of pH-neutral, protection-free soap, with occasional decon washes using a higher pH soap when needed, represents the best approach to car washing for vehicles with ceramic coatings, ensuring longevity and optimal performance.
