We have Strataglass and use the Imar Strataglass Cleaner & the Imar Strataglass Conditioner. I think that it's numbers 301 & 302 or 302 & something else... I can't remember off of the top of my head but I'll check this weekend. We buy it from Defender online.
We've also used the Imar Strataglass products on Isinglass and it also works well with that.
Just make sure that you use clean dry cloths &/or towels and change frequently. And no need to use a lot of the cleaner, a little goes a long way!
We asked 2 local Canvas people what they recommended and they advised replacing the glass as it was too late, that once it gets cloudy and sticky, you won't get it clean & clear. We proved them wrong with the Imar products and a lot of elbow grease!
Good luck!
