Hard Water Damage

I use a product called Amaz it works fast but it can be alot of work. I usualy charge $5 to $20 a pain, but some people charge athiurd of the replacmet value of the glass.

Several of the window cleaners in my area swear by a product labeled “Power.” It is bright pink, and you can get it in a 38% or 75% phosphoric acid concentration. I don’t have much experience with it personally and was wondering if anyone else had heard of this stuff and what your thoughts are on using Power or other phosphoric acid solutions.

Just be aware of the danger of tin etch haze and w/ any acid make sure to use the appropriate PPE.
I know I’m getting some of the Simple Green limescale remover Karl uses.

Okay - looked at a job today, beautiful huge house. Walked around back and saw horrible white colored hardwater stains. I didn’t have all of my gear with me, but I tried to clean a pane to see how bad it was. Wetted the glass down, took my white scrub pad, and it didn’t even make a dent. So I pulled out some steel wool and that with some elbow grease took care of 75% of the hardwater. The remaining, and the worst buildup was around the frame. The worst part is, there is a TON of cutups involved. I know I could easily land this job, we have already contracted some other work for the lady.

The hardwater is coming from the sprinklers, so I am hiring my friend to redirect the heads away from the house. What would work good for this type of corrosion without all the dangers of the heavy duty products? I wuld like something I can spray on - let dwell, scrub with steel wool or scrub pad, then hit with t bar and squeegee. A lot of work, but well worth the money$$$

Any ideas?

+1, and that is my price too. I know others that charge 20 per pane. Its 40 bucks a gallon man, you gotta make some money off of it. I am able to restore about 22 panes with one gallon diluted by about 20 percent of the gallon bottle.

try using SafeRestore

Tory,
I like that you have metrics for how many panes you can restore from a gallon. That puts it into perspective when you look down and half of your $40 bottle is gone, and your nose hairs are fried, and your eyes are twitching from the fumes on a hot-day. It sure makes you not want to underbid those restoration jobs.

Use a respirator – you owe it to yourself and your family.

You’re right. I gotta carry some respirators. I only have those cheapo little white ones that don’t seem to do much, so half the time I don’t even put’em on.

You need a respirator rated for chemical use.

How about the carbon impregnated ones for use with painting? Those should work and aren’t terribly expensive.

Of course if you are doing this regularly getting a 3M respirator would probably be wise. Aren’t they around $40 or so for the mask?

Here’s a couple.
Chemical Respirators and Masks

Here are some disposable gas masks, just scroll to the bottom of the page. I would contact them with what chemicals you are using beforehand.

These should be cooler and more comfortable than the rubber masks with filter cartridges, though I don’t know for sure…
