Windows

[Alexlind123]

Does anyone know how to get a coating of hard waterspotty looking stuff off of the exterior side windows? I tried using invisible glass, which got the dirt of but not what looks like mineral buildup. Oh, and by the way i made a cardomain site. http://www.cardomain.com/ride/2106576

if its water spots from tap water you can use some "lime away" or any calcium remover. calcium can be removed harmlessly with muratic acid, just use a cotton swab dipped in the acid and it will remove it just be careful not to let any spill on your paint, it shouldnt harm it but better be safe than sorry. remember use the acid only if its calcium build up you have

How am i supposed to know if the buildup is calcium or not? :s

Nice looking car. Love that color, but unless it is European spec, it only came with 208 hp. As far as the glass, I would try the clay bar also.

I have had good luck with Bom-ami cleanser. I think BMW even recomends it.

You will want to use the original powder formula that has Feldspar as the abrasive, as it is softer than glass and will not scratch.
I make a slurry of it with water and put it on a nylon scouring pad.

Do it before your going to wash your car though, as it can be messy.

A real good regular glass cleaner (plus most anything else) is a couple ounces of amonia and white vinegar to a gallon of distilled water. Then just add to spray bottle. And using newspaper to wipe and polish the glass. Works great and it's cheap .

polish off just about anything that sticks to glass.

You know the stuff at the store for those fancy glass topped stoves

I will try this first, there is some in the kitchen. Although it may be ceramic or some other such thing.

Took the words right out of my fingers. BonAmi works well for this problem and won't hurt anything as long as you wash it off thoroughly.

I use white vinegar full strength, works like magic. Pour a cup or 2 in a bowl and use a small terry cloth towel soaking wet with vinegar and wipe it anywhere there are spots, dissolves the waterspots almost instantly without harming paint. Rinse well with a hose when done & wash the car as you normally would. I'd hesitate using anything stronger. I used some full strength muriatic acid (hydrochloric acid, 35%) a few weeks ago to clean some stainless steel parts, worked well on the stainless but was pretty brutal on all the surrounding stuff it spilled on and totally dissolved some aluminum parts that accidently were nearby. Home Depot has muriatic acid in their garden section, comes 2 gallons for $7.59 in a cardboard box for shocking pools & hottubs. It's pretty harsh stuff, I can't recommend it but if you do use it, use propper precautions.

You must be VERY careful with solvents because you will unavoidably get some on the bodywork... whether by atomization or just plain drips and splashes.

steel wool on glass does wonders... it sounds scary, but it won't scratch!
Brings a great shine to the windshield, I have a friend with a body shop and I saw him use some on my windshield.
I jumped and asked why, but he reassured me and he was correct.

Vinegar and water cleans many things
