Aftercare
Quick answer: Ceramic coating aftercare is the routine that keeps an installed coating performing correctly -- primarily correct washing technique, periodic decontamination and occasional top-up products when the installer recommends them.
After a professional ceramic coating is installed, the main job is not to undo the protection. That means using pH-neutral shampoo, two-bucket washing, proper drying technique and keeping the car away from automated brush washes. None of this is complicated -- it is much the same discipline as caring for any well-detailed paintwork, but with a coating in place the surfaces stay cleaner between washes and the effort is lower.
Periodic decontamination (removing bonded iron particles and tar) and occasional application of a maintenance topper are the two other elements that come up in most installer guidance. How often each is needed depends on mileage, exposure and the specific coating product. A workshop that applied the coating is the right source for advice on timing -- not a general schedule from a forum.
