Cleaning a Foggy/Hazy Window Insulated Glass Unit (IGU) from the Inside, Without Replacing the Glass

ATTENTION: Windows may still temporarily fog up after this is done, especially on cold mornings. The primary goal is to remove the dry haze that makes the glass opaque.
Every time I walk past my picture window I'm amazed that I can see the outside (it was hazy when I moved in some years ago). Both windows I cleaned are perfectly clear (though they may seem fuzzy in photos) during the day. Replacement cost for the glass would have been very high (4-digit).
CORRECTIONS: (see Instructable below): An aquarium air pump is much better and safer than a compressor. Thinner needles are probably better. I did seal the holes with caulk eventually, on a very dry, cold day, and it fogged up in a few months, so I don't recommend this. I have since uncovered the holes and it's doing well - it fogs up a little but clears up on its own.

I just want to chime in and say that this video saved me 22 thousand dollars. You literally bought me a car. THANK YOU.
-
Probably the best educational video presentation for cleaning DG glass I have seen so far
-
👍 you are a natural teacher! I enjoyed watching this even though I could never do it!😂
-
Finally no music.
-
YouTube is great. Allows people to call out the contractor BS. Great job. Thanks for sharing
-
Thanks for skipping the music. Excellent work.
-
Definitely worth a try! Be careful using the air compressor air, most compressors have condensate water in the tank that has oil and/or rust in it and you will ruin the window as you aerosolize all that nastiness into the freshly cleaned window.
-
Fantastic video. Thank you for your time and efforts to produce it.
-
As many said, this is the best video presentation I have seen on this topic. Will try it out and reply back-thanks so much!
-
Worth every effort to fix those superb arched windows.

I am going to pay someone to do this because I am not handy and I do not have nor do I wish to obtain all the equipment you have around your workshop, but it has been an invaluable education on how this is done. I will understand the process when I hire the company who does this.

I am so glad I found this film. I have the same problem at my house and have done a lot of research. If you want to look at more of the same try searching 'get the mist out' or crystal clear window works. Both professional firms but the same end result. Using this set up will save me a huge amount of money. Many thanks.

Dude that was frickin awesome. Only 74 likes with 3k views? What's wrong with people. I hit like 2 minutes in.

You're awesome! thanks for the effort to showing everyone how this is done. Zero resources for DIY as folks want to charts 1k$ per window replacement.
-
Super cool video. Love your creativity.
-
Very helpful explanation. Thanks so much!
-
Great video. I have 5 large windows similar to the dome window with the same hazing. Quite to “Replace and not repair” the issue were mind boggling. I saw kits such as your going for $360.00. I will follow your procedure and comment upon completion. I will likely usa C02 to blow out the alcohol. Thanks for the video, great stuff!!!!
-
Thanks for putting in all that work and sharing with us... when they say that it can't be done I get very skeptical
-
To connect the chain of decreasing diameter hoses an adhesive like GOOP will aid joining as it will act like a lubricant and when set should give you a strong seal in the join. Great video, I will try on my cottage windows this coming summer.

I found he attached Instructable very helpful as it included a lot of the additional hacks mentioned within replies to comments. Thanks!!
