Unfortunately there is nothing on the label on the bottle in my hand that indicates what to use to strip it off. However there are clues. From the label: Avoid sodium hydrozide based cleaners. Avoid ammonia based cleaners. This indicates to me that these substances will degrade the New Glass in some respect. From my experience: Straight ammonia takes _way_too_long_ to be practical. What does work is a product -sold in Canada- perhaps in the States as well, called "Super Tuff". It is essentially an *oxalic acid* based liquid cleaner. Wipe some on, wait about 3 or 4 minutes and then blast the softened NewGlass off with a hose or a power washer. Works like magic. You want to avoid letting it sit on unvarnished teak or un-anodized aluminum for *any* length of time and you should read up on handling instructions for oxalic acid. This last bit is serious. |

Remove NewGlass
Thanks for the thoughts so far.
The newglass I used didn't come with a cleaner as newglass2 does. And I don't have the bottle so I couldn't read the instructions. I suspect my ammonia memory corresponds to the warning quoted in one of the responses. So far the only real experience seems to be oxalic acid based cleaners. But I'm hoping for better news. -- |
