How to get off water stains from A/C Condensate

Quandt · 10-01-2023, 04:35 PM

I was able to compound out stains from AC drip on the darker areas but not the lighter.
I was unsure if i should just keep compounding or if there is any other way this should be done better.

Thanks for any advice!

Try white vinegar, let it soak for a bit by taping a paper towel over the spot then soak it with vinegar.

After you get it clean, keep a good coat of wax on it.

What compound did you use, and what method to apply and buff out?

Keep roof clean, and x100 on the wax; especially where you know the drip lines may be in the future.

I used a McGuire's light compound. Totoally took off stains on darker parts of the side, also off the windows. Did it by hand with a buffing pad.

Lighter paint still show streaks

I have a light tan coach too.

I wax the sides, front & back twice a year with Mequiar #56

I use #67 or #83 on the roof, and the #56 on top for effect, but not required.

If I see a tough stain like what you are seeing, I will use the #67 or #83 on sides. I use DA Polisher as I really got good with it.

The part that may make the most difference with the compounds is the pad used, rpm speed. Drives me nuts that pads come in all kinds of colors so it is can be hard to get the right one for your needs so you don't over do it.

But whatever you do. BE SURE TO WAX AFTER USING COMPOUND to preserve. For 90% of the coach I even use the DA polisher to apply and remove the wax.

My coach is 4 years old and I have waxed it exactly 8 times. I love your decals, so curious to know what you have been using on them? I have been use 303 but some wax does get on them.
