Whether it’s getting hit by a sprinkler, splashed in a puddle, or an unexpected rain shower, mineral heavy water and airborne contaminates can cause spots and damage to your vehicle’s finish.

On Clear-Coat Finishes:

On modern clear-coat finishes, most of the spots will be cosmetic and easily handled. A microfiber rag and our Detail Pro Hard Water Spot & Scale Remover can be used buff out 2 foot by 2 foot sections of a vehicle. Work the Hard Water Spot & Scale Remover over the vehicle’s finish and then follow up with a clean microfiber rag and our Detail Pro Detailing Spray to clean the product from the painted surface.

On Single-Stage Painted Finishes:

On classic cars with a single-stage painted finish, where paint can be porous and discolored by contaminants and water spots, water spots can be eliminated, but there are often more steps to the process. The first step is the same as on modern, clear-coat finishes. Wipe the vehicle down with Detail Pro Hard Water & Scale Remover, and then clean the surface with Detailing Spray and a microfiber rag.

After washing and drying your vehicle use a clean hand (or place your hand in a plastic sandwich bag to increase sensitivity) and rub the surface of the vehicle. You might encounter areas that water spots have been corrosive to the painted surface or clear coat. These areas will require additional attention.

Clean and dry your vehicle to remove as much of the dirt and contaminants as possible. Now you’ll use detailing clay to remove the mineral deposits left by hard water. Using detailing clay will remove above-surface bonded contaminants. Knead and stretch the clay into a comfortable 4-5 inch pancake that fits comfortably in your hand. Place the clay in your palm with your finger tips extending beyond the clay (this will help avoid pushing holes through the clay). Spray the surface of the vehicle and the clay with Detailing Spray to lubricate. The pressure necessary will vary based on the contaminates on the surface. The clay will find resistance where contaminants exist and will remove them from the surface. Continue to clay the surface until the surface feels smooth.

Once the above-surface contaminants are removed you’ll now need to address the subsurface defects caused by scratches and hard water etching. For this you’ll want to use Detail Pro Heavy Duty Compound. This is an aggressive compound that will buff out surface scratches and subsurface imperfections like hard water etching. Using a rotary polisher, like the Cyclo 5-Pro Mark II, you can quickly work the surface to remove scratches and spots caused by corrosive hard water.

The final stage in hardwater spot removal will be the seal the surface to prevent future damage. By hand or using the Cyclo 5-Pro Mark II apply Detail Pro Pro Wax to seal and protect your vehicle’s finish.
