how to remove hard water spots from paint

Recommended Posts

Hi Guys,

I'm totally depressed because I can't get pissed off at my wife.

I've spent hours and even days washing and waxing this vehicle but all it took was one night parking in front of her sister's house was all it took to get major water spots everywhere due to the sprikler system.

I've tried clay bar, polish, and waxing but I'm still seeing the water spots.

If I can't remove the spots, I'm going to treat this vehicle like and other car in the house and just let it be....i dont care anymore....

I'm so pissed

I had this problem a while back and used lime away to remove the water spots. (I believe C.L.R. will work equally as well.) I just sprayed it on and was able to effortlessly wipe the spots off with a sponge without damaging the paint. I had just about thrown in the towel (pun intended) as no amount of washing / waxing ever removed the spots.

I heard vinegar works too. I had this yesterday but was able to wash it off after a few hours being sprayed by the sprinkler. If nothing works still, try some Goo Off spray.

White vinegar worked great for me. I spent a couple of days buffing out water spots - one freakin spot at a time. I used lots of micro-fiber towels and 50/50 solution of distilled white vinegar and distilled water. Sometimes I used 100% distilled white vinegar. There were a few stubborn spots that were hell bent on sticking to my bumper, so I used a color wax treatment. My Boxster is black, I used black Color Magic. This worked great - no more spots. Then, I had my car professionally detailed to bring back that factory showroom finish. :)
