Why are water stains so hard to get rid off?

The reason why water stains are so hard to remove from car paint is because of the combination of all the minerals inside the water that is being applied to your car. A common name for this type of water is hard water.

This water contains a lot of minerals, like calcium and magnesium, that eat at the car paint. As water evaporates, those minerals inside the droplets leave behind a stain on the surface. In order to permanently get rid of water stains, you need to first get rid of those minerals and then polish the spots where these alkaline water mineral stains damaged.

How to spot remove bad water spots

Sometimes after using a homemade spot remover you can still have some water spots left. This is where a commercial heavy duty water spot remover will come in handy.

All spot removers have different ingredients but there are a lot of common elements. Usually, distilled water is the base, with mineral oil is added as a lubricant. Other ingredients that are commonly included are solvents, absorbents, conditioners, and buffers.

Any remover shouldn't be used on matte surface paint jobs unless it says that it will not damage those surfaces.

Step 1: Use quick detail spray

To get rid of any remaining dirt, apply some of the quick detail spray for a waterless wash solution.

Step 2: Apply product

Apply your chosen water spot remover on the affected area with a foam applicator or a microfiber applicator.

If you are using a gel remover, you might get some water spot gel residue that will need to be buffed out to remove.

Step 2: Rub it in

Rub in the spot remover with two or three passes to remove water stains.

Step 3: Clean the surface

Grab a dry and clean cloth and finish off the surface by rubbing off the compound.

Clay bar treatment

If after using a commercial cleaner you have any etch marks left from the hard water spots, you should use a detailing clay bar. Clay bar successfully removes water spot stains and makes sure that none of them come back. One crucial thing to remember is that you need to use this technique very carefully and on smaller, localized sections that require water spot removal.

This Chemical Guys Heavy Duty Clay Bar and Luber Synthetic Lubricant Kit, is perfect for water spot removal. This product will leave a silky smooth finish with a mirror-like appearance. It is safe for all aluminum, chrome, glass, paint, and all other pained finishes.

Step 1: Start with a clean car

Before using clay, make sure that your car is fully washed from any loose dirt.

Step 2: Soften the clay

Grab your clay in your hand and squeeze it until it is a pliable disc. The warmth of your hands will soften the clay as you work on it. Once it is soft and ready, flatten it into a circular shape.

Step 3: Spray the lubricant

Generously spray a lubricant on a section of water spots you will be working on. A section should be big in order to prevent damaging the paintwork.

Make sure that your section is not only just misted, but saturated with the lubricant. In addition, spray some of it on your clay disc for some extra lubrication.

Step 4: Start working with clay

Slide the clay back and forth over the lubricated area. Flatten your hand and pin the clay disc gently against the car with your fingers. Rub in side to side or up and down motion. Do not rub in a circular motion since this might create scratches.

Add more lubricant if you feel like clay is sticking to your vehicle's surface.

Step 5: Work on different areas

As you move along to different parts of your car, you may notice that the clay is getting dirty with contaminants. When that happens, fold the clay disc over and flatten it out so you have a clean surface.

Repeat these steps until you get rid of all the spots.

Step 6: Wash off the lubricant

Wipe the area with a clean and damp towel to remove any residue. Wipe the area thoroughly but not aggressively.

Step 7: Apply wax

After using clay bar, it is recommended to use a paint sealant or wax protection. Waxing or sealing protects the paint from future water spot contamination and from any corrosion.
