Let’s talk about what mineral deposits do to your hydrophobic coating and how, at AJ Auto Detailing, we can help you fix and maintain it.
Hydrophobic Coatings 101
A hydrophobic coating is an extra finish you put on your car’s exterior to protect it from water, dirt, and debris. It is made of water-resistant material that repels any liquid that comes into contact with the surface.
Adding hydrophobic coatings to your car is a great way of protecting it from exposure to the elements and maintaining a new and glossy look. Though, it’s also important to take care of the coating as well as other parts of your car.
Why Mineral Deposits Are Bad News For Hydrophobic Coatings
Hydrophobic coatings work by creating a slick, water-repelling surface that keeps dirt, grime, and contaminants from sticking to your paint. But if your vehicle is exposed to hard water, full of minerals like calcium and magnesium, those minerals can dry onto the surface, leaving behind stubborn spots.
If left untreated, mineral deposits can:
- Etch into the coating and weaken its protective properties
- Create unsightly spots that dull the shine of your paint
- Shorten the lifespan of your coating
- Potentially damage the clear coat underneath if severe enough
The sooner you tackle mineral deposits, the better your chances of fully restoring your coating’s performance and appearance.
How To Spot Mineral Deposits On Your Hydrophobic Coating
Spotting potential mineral deposits early on can seriously improve your chances of reducing any damage and expensive repairs. If your car has a hydrophobic coating, make sure to watch out for cloudy or chalky spots appearing after rain, reduced water beading, and texture changes embedded into the coating.
Can You Remove Mineral Deposits At Home?
Some mineral deposits are small enough to remove at home, though you’re risking not eliminating them entirely and letting them continue to damage your coating.
Mild water spots might come off with gentle washing or vinegar-based solutions. But if the minerals have bonded strongly to the coating or started etching into the surface, DIY methods can scratch the coating or paint, embed the minerals deeper in, or cause uneven surface damage.
Professional treatment is the safest, most effective way to remove mineral deposits without harming your hydrophobic coating, especially if you want to protect your investment long-term.
