Water Spots and how to remove them


Water spots on paint and glass are very unsightly and disturbing in appearance. Water

spotting can also appear as a permanent mark and are most times very stubborn to remove. We

will educate you on this irritating matter so that you can understand what they are, how to

remove them, and how to keep them off.


There are 2 types of spotting that occurs on surfaces, Etched water spots, and Surface water

spots. If you can afford to have this corrected by an Auto body shop or a professional Auto

detailing company, I would highly advise it as this may prove to be a very labor-intensive

endeavor. If you would like to try and first remedy the problem on your own and have more time

then money, please read on.


Etched water spots damage the surfaces by eating the paint or glass leaving mini craters

and are by far the most difficult to remove. The term used to describe water Spot etching is called

sulfuric corrosion. Rainwater by itself is normally demineralized and pure enough to evaporate

without leaving any marks but if you live in places of high industrial air pollution or have an

active volcano nearby, there may be chances of having acid rain causing this type of damage.

This type of water leaves behind spotting that is most times permanent if not removed

immediately. To remove them from glass requires buffing with cerium oxide powder and for paint

requires countless hours of buffing with various compounds. In some severe cases, the glass may

need to be replaced and the vehicle may need to be repainted.


Surface water spots are a more common problem and it’s caused by heavily mineralized

liquids known as hard water. Hard water comes from wells beneath the earth’s surface. When

water travels through the earth to get to these wells, the water will absorb a lot of minerals on the

way down. When the water is pumped from the wells and is used to wash your vehicle, it will

leave behind spots if it isn’t wiped off in time. Water evaporates leaving behind the minerals in it

to appear on your paint when it dries. Sometimes when water spots are bigger than a quarter, you

can see the center is clear and the edges are white. Majority of these minerals are calcium and

magnesium. Gravity will pull these minerals to the edge of the water where you will see that

white colored mark. This is why it is important to wash your vehicle in the shade when it is cool

to the touch and out of direct sunlight. Proper wiping of still water is highly advised when drying

your vehicle. Leaving hard water to remain on your paint even if temperatures are cool may still

leave spots if the mineral content is high. Be sure to wipe your vehicle off quickly if the water in

your area has this problem. Leaf blowers make quick work of this task and are a blessing to have

for painless and efficient water removal.


Removal of surface water spots has various techniques for paint and glass. The internet is

plagued with a very vast field of information from using toothpaste, vinegar, baking soda,

oranges, lemons, steel wool, clay bars and tons of other chemicals. All these cheap anecdotes may

work to a certain degree but are useless in coastal areas where mineral content in water tends to

be a lot higher. There is also a multitude of professional products that claim to make this

endeavor less labor intensive but the best thing to do is your own research and drum up your own

conclusions. If you want to cut out all the headaches of seeing what works, I would highly suggest

purchasing Sud Factory Spotless X2for glass and Sud Factory Dissolve X2 for paint. If you are rich and have

thousands of dollars to throw away, go ahead and buy every product on the market and see what

works (I’ve already made that mistake). Just follow the instructions on the bottle and you’ll be fine.

Once you are able to remove the spots and have the desired polished look on your vehicle, it

would be best to install a sealant, coating or wax to protect your work. Sealants, coatings, and

waxes provide surface tension which makes the water slide off a lot easier. A lot of people make

the mistake of thinking that there is a waterproof shield on the vehicle which is not the case. If

it is nowhere for the hard water to go and it is left to dry, it may still Spot up. If the surface

has a coating of some sort, the coating then absorbs the damage making it easier for you to bring

the gloss back to your paint and re-coat your vehicle. Think of it like wearing a jacket while you

walk across sprinklers versus having plain clothing. You could easily replace your jacket while

plain clothing would leave you drenched and dirty.


The best way to prevent hard water spotting is to just avoid sprinklers, practice proper

drying techniques and wash your vehicle when it’s cool to the touch and out of sunlight.

Coatings, sealants, and waxes are the way to go for easier cleanup and a worthwhile investment

to protect your vehicle. Another sure-fire way to prevent hard water spots from forming is by using

Sud Factory SFX1. Sud Factory SFX1 was designed to protect your windows from water spots by helping the water

slide off the windows. It has a 6-month protection which means once you apply it, you don’t need to worry

about water spots sticking and can be easily wiped away using a microfiber towel.
