The most common form of water spot removal is known as regular spot removal. They generally develop when excessive water leaves behind mineral deposits especially calcium and magnesium on your vehicle’s exterior. Severe etching can sometimes be expensive and very difficult to remove. It also makes the paint look bad. Regular spotting can be removed by washing it off using an alkaline cleaner and cold water. This is a temporary fix, and you will have to repeat the washing procedure until you get rid of it completely.
If regular spotting is still not removing all traces of minerals, then you will have to try a more aggressive solution. There are many products available on today’s market that have high pH values and are used to neutralize any excess minerals. One example of this is a high or product with baking soda and white vinegar. You can spray this over the spots and allow it to sit for a few hours. The baking soda and white vinegar neutralize the minerals in the water and draw them out of the surface.
When you have removed all the spots, make sure that you clean the windows thoroughly. Use a very soft cloth to wipe the windows to remove any remaining hard water stains. If any residual deposits were not removed, they will be present once you wash the vehicle again. You should also wash your car windows regularly to prevent stains from reappearing. These stains are very stubborn and you will need to maintain your vehicle to keep these stains away.
After you have cleaned and dried your vehicle, you may find that you have more hard water spots remaining. These will be the result of the salt and minerals remaining in the exterior paint. To deal with this problem, use a salt-based product like Rock salt to dissolve the deposits and to prepare the surface for paint application. This will help get the mineral and salt content to a minimum, therefore less protection is needed to prevent damage to the paint.
If regular water spots continue after you have done everything you can to prevent them by washing, using the salt solution or by adding mineral additives to the car windows, it is time to call in a professional. Exterior painters are used to dealing with these types of stubborn deposits and they do not take kindly to them. It can take weeks or even months to resolve the problem, so don’t take it lightly. The paint can crack if regular treatments are not used, and the interior of the car can become seriously damaged. You will want to consult a professional about the best course of action to remove these stubborn deposits from your car windows.
If you do decide to consult a professional, make sure you know what type of compounds they are used to remove the hard water spots from your car’s paint. Some types of cleaners are more suited for specific types of stains than others. Many car owners choose to use a combination of products that are designed to remove many of the hard water spots, along with removing the original color of the paint. These products are usually water-based and may contain abrasives to remove the minerals and to make the surface less harsh. They can also be made to coat the entire surface with a protective film.
Other options for removing stains include using an all-natural product like an all clay lubricant. This can be found at any major department store and is easy to apply and remove stains from. All-clay products work to not only remove stains but to improve the overall appearance of the vehicle’s finish as well. Since the majority of cars are water-based, it is very unlikely that the material will damage paint.
One type of product that has been effective for removing stains from the paintwork of older vehicles is polyurethane cleaner. This type of compound will usually need to be used on freshly painted surfaces. Many of these compounds will leave a thin film of polyurethane on the surface after they have been applied. However, most of them will not penetrate deeply enough into the paint to cause any damage. The product will help to lift up the areas where there is a buildup of dirt, rust and grime, and will then help the rest of the paintwork to follow the original color scheme of the vehicle.
