A few things from your kitchen will tell you if your glass can still be saved.
Coating only works on clean, clear glass.
We would rather you test first than buy and be disappointed.
Some sit on the surface. Some have already gone into the glass.
Once you see water marks, at least 7 or 8 in 10
are the second kind.
You already have what you need. Most of it is waiting.
Whether the marks on your glass are on the surface, or already inside the glass.
Glass still new and clear? Skip the test and coat it now.

The test spot is fully clear and wipes off with a sponge, so the marks are still on the surface.
You can buy EnduroShield right away. The EnduroClean in the kit takes them off the same way: clean the whole panel, then apply the coating.
Each kit comes with EnduroClean, the coating and the tools, so you can do it in one go.

A faint trace means a little of the marks have already gone into the glass.
If you can live with it, a layer of EnduroShield stops it getting worse, so the marks don't keep building up.
Clean the glass with EnduroClean first, then apply the coating.
The marks have gone into the glass. Basically no cleaner on the market can help, so hold off on the kit for now.
What your glass needs is polishing (grinding away a very thin layer of the glass surface). Coat it right after polishing so the marks don't come back. Our team can do this at your home.
Honestly, polishing can't get it to 100%. It usually gets to 90 to 95 out of 100: clear from a distance, with maybe a little left at the edges up close. We always look at your photos before we come over.
