I have come to the end of the line with this product. I’ve been testing it for a few months now, and have made multiple applications on many windows, some my own, others on customers windows. The main purpose of the tests were to establish whether nano ultra does keep windows cleaner longer. In every test I’ve done the answer is a clear NO.
It simply doesn’t work. The theory of rain flushing the window clean is a flawed one, as rain is rarely so heavy that it floods down the window, and the increased surface tension of the glass seems encourage dirt to cling to it, and in any case, even if you spray the window with a hose it still wouldn’t loosen dirt that was just sitting on the glass. Also, on a few of the windows, the sealant failed within a month.
The only plus point to their product range is the stain remover and polish, which is very effective at removing difficult, stubborn stains, but to be honest, I imagine you can just buy any cerium oxide based product that would do the same thing, at a fraction of the cost.
So anyway, not impressed. Won’t be using it again.
I don’t really know to be honest. I expect it is, as the water sheets evenly. We don’t really have to protect glass against hard water stains in the area I live in as its not a common problem, but if I were to use that as my selling point I would probably be inclined to use a hydrophobic sealant, they tend to be cheaper as well.
Were you using both products? The first step product is supposed to remove the stains and fill the microscopic pores making it hydrophyllic instead of hydrophobic. But then you have to use the second step product to put a barrier over this newly restored glass surface. If you just use the second step without the first it won’t work right.

So, were you using step one only, step two only, or both products on each application?
By the way, did you experience a window that was previously hydrophobic and after using the 2-step nano-ultra products (both products, hence the 2-steps) seen that it made the window hydrophyllic instead? That would be the main reason I’d use this product, to make cleaning windows with WFP easier.
It should Larry. I haven’t used this product but have used other cerium oxide based cleaners and they did help some, but they only claimed to be a protective barrier for 6 months. Some are better than others. I haven’t used Nano-Ultra yet, but would consider it highly on a large job where a lot of hard water stains had to be removed. Especially if I suspected that the owners weren’t going to fix whatever reason had been causing all that staining. So… you pitch this product but don’t know if it is preventing hard water stains? :rolleyes:
Or do you use a different product made to do the same thing?
Yes, I am fully aware of how to use the 2 step product, both steps were completed on every window I tested it on. By the way, it doesn’t fill in the pores. The cerium oxide (step 1) is mildly abrasive, and is used to smooth out all the pores on the glass so that the glass is perfectly smooth, even at a microscopic level.
