What to avoid with ceramic coating?

To maximise the lifespan of a ceramic coating, avoid automatic brush car washes, dish soap, abrasive clay bars, traditional car waxes, dirty wash mitts, and letting bird droppings, bug splatter, or hard tap water bake in the sun. Stiff bristles and harsh chemicals strip the coating's hydrophobic layer, while baked-on contaminants etch directly into it.

On the Sunshine Coast, intense UV accelerates etching from bird droppings and tree sap, while mineral-heavy tap water left to dry on the paint leaves stubborn, hard water spots that gradually degrade the coating surface.

Washing habits and tools to avoid:

Automatic brush car washes — abrasive nylon bristles and dirty brushes from previous vehicles inflict heavy micro-scratches and swirl marks that dull gloss and reduce water beading; prefer hand washing with the two-bucket method, or a well-maintained touchless wash if hand washing is not possible.
Wrong shampoos and cleaners — dish soap, strong degreasers, "wash and wax" shampoos, and products with heavy gloss enhancers or waxes strip or clog the hydrophobic layer; always use a pH-neutral shampoo formulated for ceramic coatings.
Dirty wash mitts and towels — old beach towels, sponges, or dirty microfibre mitts grind contaminants into the coating, causing scratches; use clean, high-quality microfibre and always pre-rinse before wiping.
Letting water air-dry — even with a hydrophobic surface, tap water left to dry in direct sun leaves mineral deposits and hard water spots; always dry with clean microfibre towels or a blower.

Products and treatments that damage a ceramic coating:

Traditional waxes and polishes — ceramic coatings replace the need for wax; carnauba waxes or traditional polishes clog the coating surface, and polishing actively strips the coating off the paint.
Abrasive cleaners, compounds, and clay bars — mar or physically remove the coating; use a dedicated, coating-safe remover for stubborn contaminants instead of aggressive scrubbing.
Stacking random waxes, sealants, and toppers — waxes and many spray sealants do not bond properly to ceramics and mask or reduce beading performance; if boosting performance, use a dedicated SiO₂ or ceramic-compatible topper rather than generic "spray wax".

Contaminants and environmental exposure to avoid leaving on the surface:

Bird droppings and bug splatter — highly acidic and can etch through the coating within hours in direct heat.
Tree sap, brake dust, and industrial fallout — bond to and chemically attack the coating if not removed promptly.
Hard water and acid rain — leave mineral deposits and contribute to chemical erosion, particularly under intense sun.

Cure window and maintenance pitfalls to avoid:

Washing too early — during the first 24 to 48 hours the coating is still hardening; harsh water, washing, automatic washes, and high or low pH soaps can interfere with proper curing and bonding.
Water and bird exposure in the first weeks — for the first couple of weeks keep the car dry and out of trees and bird zones, and strongly avoid automatic washes while the coating fully cures.
Skipping periodic decontamination — coatings are not zero maintenance; built-up contamination reduces gloss and hydrophobic behaviour, so perform gentle maintenance washes every 2 to 4 weeks and a coating-safe decontamination (such as iron remover) every 6 to 12 months.
