Alex nailed it with the oils making the frost more transparent. Acid etching usually requires you to remove glass and not just hit it with cerium.
I agree with WWS. If the etch is what I call a wet etch you have to remove glass. This involves grinding then polishing. A vapor etch will sometimes yield to a quick cerium polish. I will never forget one of Marc Tanners quick videos showing how cerium was able to remove water stains quicker than acid (CC550).
And thanx Alex. Although the Wobble isn’t really that special. It is the idea of using a universal joint in line with the shaft of the drill motor or grinder that is powerful. This keeps the grinding/polishing disk totally flat on the glass at all times during the process. It still confounds me that no one has copied this tool. I wish some manufacturer would. Cuz it would help to change the glass restoration industry.

I don’t do much hard water stain removal. when I do it irs just if the customer asks me.
I never try to sell it. When they do ask I guess my price is to high nobody ever goes for it. 
The few I’ve done have been with one restore I do fear smoking a piece of glass if I get the Tim side. I read you can tell where the tin side is with a black light how does that work ? . I am by no means a pro with glass restoration.
I am Familiar with some of the products used for it. Would Defenetly like to get your wheel , an the cerium oxide .
How does the process go when doing it with this technique. ?
Is it just the wheel you sell them I have to get the drill ?
One more question with one restore if there is damage done … Whatever type it’s always fixable with cerium an the wheel ?
What is the Tim side? Do you mean tint side? I can answer many questions feel free to txt me anytime.

Yes tint side. Typo. Definetly hit me up with your number I’ll call you one day next week.
What time zone are you in ?
Thanks
I am going to see if my machinest will write down the specs for the Wheel so I can publish these. Then anyone can take them to a local man and have a similar wheel built. Mine cost me 300 to have built. The six inch. I have a small wheel of 3 inches that cost about 140. I use both with my Slow Release Compounds that can be made with any type of superabrasive powder. I have a video of my Wobble Wheel on my blog.
Etched glass is usually not an easy fix. Most times cerium is not a simple solution. Glass must be removed. Cerium cannot remove enough quick enough. In my opinion.
Float glass has two different sides;…a tin side and an air side. The tin side faces down as the glass floats down the tin bath. The air side faces up. You might want to check out some of the embedded videos in my post “A Glimpse of the Ghost Particle?” on my blog. Here is the link. http://glass-smart.blogspot.com/

Mr. Hard water with the “powder” and steel wool pads will remove it
that makes sense
So you might want to use One Restore diluted, 3 parts water to 1 part on One Restore.
CC550 not glass cleaning agent.
But glass CLEARING AGENT.
Here video explaining this.

Tin side is not a mistake he is referring to the tin coating that is usually found between the panes but is some times applied on the out side. Some windows have a tungsten or titanium coating applied to on them. If I’m not mistaken polarized sun glasses will reveal if the tin side is facing out. Using acid to clear windows especially cc550 is not the safe way to do it. Polishing windows is the safe way.

You are referring to low e coating. Low e is usually installed inside the ig unit. And yes polarized sunglasses make this coating obvious. You can see this coating with the naked eye very easily as well, the reflections will have a blue or purple look.

What do you mean flagged??
don’t know what that means, it’s a dsystem message when you withdraw a post. you can still see the post byclicking the pencil top right
Oh pity it was a good post with a lot of ideas on this subject.
One restore reacts with the tin side as well so it would not be a good option.
Polishing is a safe solution if you know what your doing and know the polishes your using. The risk with polishing is swirl marks. I can’t tell you how many polishing products I have used, that guaranteed no swirl marks, but left swirl marks. Restoration work can be a frustrating bear.

I think he meant tin side, tin etch haze is the reaction of cc550 with the tin side of float glass.
