Whether you’re driving along the coastal roads or parking in town, a ceramic coating can keep your car looking sleek and clean for longer. However, to get the most out of this high-performance protection, you need to follow the proper maintenance routine.
In this ceramic coating care guide for Guernsey, we’ll go over five essential tips to help you maintain your ceramic-coated car and preserve its glossy, water-repellent finish.
5 Essential Tips to Maintain Your Ceramic Coated Car
Wait before washing after application
One of the most common mistakes people make is washing their car too soon after having it coated. If you’re wondering what not to do after ceramic coating in Guernsey, this is at the top of the list.
Your ceramic coatings need time to fully cure. Depending on the product used and weather conditions, this can take 24 hours to a week. During this curing period, avoid any type of wash, manual or automatic, and keep your car away from bird droppings, tree sap, or rain if possible.
Ask your detailer how long the specific coating they used requires to cure and follow that timeframe strictly.
Use a pH-neutral car shampoo

Once your coating has cured, the best way to wash your car is by hand using a pH-neutral car shampoo. Regular household soaps or degreasers can degrade the ceramic layer, reducing its effectiveness.
Look for shampoos designed explicitly for coated vehicles. These will gently lift dirt without harming the hydrophobic layer. To minimise swirl marks and contamination, use the two-bucket wash method: one bucket for soap and one for rinsing your mitt.
Dry properly after each wash
After washing your car, drying is just as important as the wash itself. Leaving water to air dry on the surface can lead to water spots that look bad and become stubborn over time.
For Guernsey Drivers, the salty coastal air can leave behind mineral deposits, so drying your car thoroughly after a wash is essential on the island. Use a clean, soft microfiber drying towel or a dedicated car dryer. Avoid bath towels or chamois, which can drag debris across your paint and cause scratches.
Top up with a ceramic coating booster
Even the best ceramic coatings will wear down over time. A great way to extend the lifespan and performance of your coating is by using a booster spray. These products help refresh the hydrophobic effect and can add another layer of UV protection.
Typically, a ceramic booster should be applied every three to six months, depending on driving conditions and exposure. If you’re unsure what to use, consult a local expert who understands aftercare for ceramic coatings in Guernsey.
Avoid automatic car washes
If you’ve been used to running your car through a machine wash, it might be time to switch up the routine. Most automatic washes, especially those with brushes, are too aggressive for a ceramic-coated car. They can reduce the coating’s effectiveness and even leave behind scratches.
If you’re short on time, consider a touchless wash as a backup, but only if it’s free of harsh chemicals. The best long-term solution is a regular hand wash schedule, or even better, a mobile detailing service that knows how to handle coated vehicles.
Additional aftercare tips for ceramic coatings in Guernsey

Maintaining your ceramic coatings isn’t just about keeping them clean. It’s about protecting your investment. Here are a few extra tips:
- Park in the shade or under cover when possible to limit UV exposure.
- Rinse bird droppings, sap, or bug splatter immediately. These contaminants can etch the coating if left too long.
- Inspect your coating every few months. If water no longer beads or sheets off, it might be time for a booster treatment or professional inspection.
- Use microfiber towels whenever you touch the car. Always make sure they’re clean and free of debris. (Use at least three to five microfiber towels each washing)
