water spots on car windows?

Question

i have a mobile detailing company and i have hired the best of the best to ensure people or more than happy with there car, my only problem is windows. i have found that auto windo cleaner works on everything but windows. i still get water spots. i'm not sure but i think its hard water. i have tried regular window cleaner, auto window cleaner, rubbing alcohol, degreaser sprayed on a rag, viniger, and a few variations of some of these things deluted. i hear that steal wool will do it but it only makes sense to me that even fine steel wool will scratch the windows at least a little, and when dealing with $100,000 cars i dont want that mistake to happen. please help (yea, i know, if they were "the best of the best" then i would have this problem right? well, there the best in certain things, one at interior, one at wheels and tires, and ones and washing and waxing and clay bar, nobody for the windows)

Answer 1

Mr clean makes a car wash kit, I know it's not for a pro but they have a sprayer that has a filter in it, Works great. I used in on many vehicles. One is a all black Land Rover Discovery.. looks great when done and don't even have to hand dry it...

Answer 2

I have hard water too. When I wash our cars the first thing I do is use a squeegee on the windows before they dry. I use a shower stall squeegee and a lint free cloth. You can use a California Blade if you want. You can get them at autozone, Advanced auto. I don't really like it. If you get water on them when you dry off the rest of the car wipe them immediately with the lint free cloth.
Using a SOS pad or Brillo pad will not scracth the windows. Use a real fine steel wool. Do this while washing the windows. Rinse immediately, and rewash the windows with the regualr wash water. Do not put the SOS pad or steel wool in the wash bucket. Do not use steel wool on a after market window tint. Only a factory tint on rear window. There is two layers of tint on the rear window, one inside and the other on the outside.
Also use a spot free car wash. Also do it in the shade. I have a Black GMC Sonoma and a Salsa Red Equinox and I don't have water spots on the windows or paint. And everyone knows a Dark color is the worst. The worst is the back window. The beat window cleaner I've found is Rain X. You can use it on tinted windows inside and out.
My wife and I get all kinds of comments about how good our vechiles look. People ask my wife who does are cars? She says"My Husband". They all so ask "How much to do theirs?" Would he do mine? Maybe I ought to start my own detail shop. But I'm almost 60 years old and I think it' a little late.

Answer 3

Probably the best way to beat this is not to let them form in the first place. You have a shade/canopy to work under? Dry the car before the spots form. You also could try rinsing with distilled water before the car dries. Once they are there, vinegar should remove them. Don't even think about using an abrasive like steel wool(!)

Believe it or not, we installed a shower head that has a carbon filter cartridge in the handle to solve part of the problem, but this is not a soft water treatment system, which can cost you upwards of $600, and then to clean the windows we use Soft Scrub (no bleach), and softly rub the windows with plenty of water and then squeegy the water off immediatley. This solved this problem very inexpensively and easily. Good luck!

Answer 5

try generic white coffee filters . i use tem on my tv and my windows.

rain-x exterior in the spray can works well. you wash your car then use any window cleaner to remove the remaining stuff left behind by the soap. follow the directions on the can but instead use a generic coffee filter instead of paper towels or cloths on the glass. works on the mirrors. it takes several washings before the rain-x comes off unless you use wiper fluid a lot.

i don't meant to sound like an advertisement but rain-x also has a wax-as-you-dry that gets rid of the water spots on my black suv.

Answer 6

try using a good wax on the windows inside and out i worked at a detail shop car wax

Answer 7

use Mothers metal polish with a cotton cloth, it wont scratch, only bad part is its a lot of work. you can also use a buffer with this polish but be very careful not to let it get too dry and also don't hit the rubber seals around the glass

Answer 8

I use glass wax. You have to order on the net. I run a cleaning business.

Answer 9

YES IT IS THE HARD WATER ON YOUR WINDOWS. TRY THIS IT WORKS. GO TO THE NEAREST AUTO PARTS STORE AND BUY A CAN OF DUPONT POLISHING COMPOUND {SMALL GREEN & WHITE ROUND CAN}. APPLY ON WINDOWS WITH PAD. LET DRY. WIPE WITH CLEAN RAG. BRAD

Answer 10

if you go to any hardware store, you can get a product that is specifically made to remove hard water spots from windows, i dont think its that expensive, and it comes in powder form, so you can stock up on it.
