Acid rain? How can I get this out?

[porschemacanshawaii]

Hi all,

This my first post on the forums. I'm in need of everyone's help. I washed my car today since it's been a while. Upon washing my car, I found this stain that looks similar to bird poop but I don't remember having any of that in my car. I would have noticed it and washed it right away.

It's been raining here in Hawaii recently and I'm thinking it might be acid rain since it does drip downward.

Any ideas on what it could be and if this is something I can correct or would I have to get the car repainted?

Thanks in advance.

if you can't wipe it off with some QD, then try using some polish and a foam applicator and see where that gets you...

What makes you think that there is acid rain in Hawaii? If there were, wouldn't it be over your entire car, especially the hood and top?

I tried wiping it off with some quick detailer but nothing happened. This is the picture after. I'll try some polish and see what happens.

[porschemacanshawaii]

RSurfer. That's true. It would be all over my car. I have no idea what this stain is from.

Have you parked in a parking garage recently?

Have you parked in a parking garage recently?

Yes. I park in a parking garage for work. I did some research and found that it could minerals from the garage. I tried using some white vinegar and water now and it didn't work.

It could very well be efflorescence from the concrete floors. Had a corvette that had efflorescence stains, but it was on his chrome wheels and I used Meg's Wheel Brightner that took it right off. I would not suggest using Wheel Brightner on your paint.
You might try a water spot remover and hope it works.

Thanks for the information. Any recommendations on water spot removers?

I'll pm you.


As long as you're not breaking forum rules simply post it in this thread?

Why do you need to go to PMs?

:dunno:

Hi porschemacanshawaii,

Here's your pictures uploaded to your gallery here and then inserted to make them easier to see....

From the pictures, it looks like the stain has penetrated the clearcoat. Let's hope this is not that case because if it is the only way to remove them will be to polish the affected area or get more aggressive and COMPOUND and then polish the affected area.


I'm not sure what rsurfer is PMing you my guess is something that isn't sold on the AG store. If it is sold on the AG store I'm not sure why he feels compelled to take his information to a private message?

Regardless...


Here's a list of water spot removers available on the AG store... I'm not even sure if there are any other water spot removers available as we carry quite a selection.

CarPro Spotless Water Spot Remover (http://www.autogeek.net/best-water-spot-remover.html)

Optimum MDR Mineral Deposit Remover, water spot remover for paint, water spot remover glass (http://www.autogeek.net/optimum-mdr-water-spot-remover.html)

Meguiars Water Spot Remover (http://www.autogeek.net/meguiars-water-spot-remover.html)

Duragloss Water Spot Remover (WSR) #505 (http://www.autogeek.net/duragloss-water-spot-remover.html)

GYEON Water Spot 500 ml (http://www.autogeek.net/gyeon-water-spot.html)

Meguiars #47 Hard Water Spot Remover is a boat polish for fiberglass boats that cleans the gel coat and prevents further oxidation. (http://www.autogeek.net/hard-water-spot.html)

McKee’s RV Water Spot Remover Gel, best rv water spot remover (http://www.autogeek.net/rv-water-spot-remover-gel.html)


That's seven different water spot removers. Most of the above are formulated to remove hard water spots which is the generic way of describing MINERAL deposits. The word HARD in the description hard water spots means minerals deposits.

Again, from looking at the pictures, it looks like whatever corrosive substance landed on your car's paint penetrated INTO the paint and those spots are not simple deposits sitting on the surface. Thus a water spot remover likely won't work and what you're going to probably have to do is compound and polish the paint and HOPE you have enough clear to remove the spots without abrading past the clearcoat and into the color coat.


The other remedy rsurfer pointed out, and that others will often point out without at the same time mentioning the SAFETY ISSUES is a a wheel cleaner that contains HYDROFLUORIC ACID, which if you get this on your skin, into your eyes, ingest it orally or breathe it into your lungs it can cause major damage to your organs.

Hydrofluoric Acid is also used to remove topical water spots not spots that are caused from some corrosive substance that has penetrated INTO the paint.

As for using vinegar to remove the spots on your car's paint you're just another person that probably read or heard misinformation which is very common when it comes to the topic of using vinegar to remove water spots.

Does it work? Only if the water spots are caused by some form of Calcium Hydroxide.

I explain the fallacy of trying to use vinegar to remove water spots here,

Using Vinegar to remove water spots (http://www.autogeekonline.net/forum/hot-topics-frequently-asked-questions/52347-using-vinegar-remove-water-spots.html)


The article also points out something everyone else leaves out and that is if wipe you car with vinegar you'll likely remove any wax or sealant protection. Thus the paint needs to be re-waxed afterwards.
