I have met so many customers, cupboards full of these products, just wasting their money.
Now here is a product we know works. Restorex takes away the residue, but you have to scrub the first time. The "other" products simply take away soap scum. What is also on your glass are mineral deposits, which are not removed with these other "magical solutions".
The key to keeping the glass clean is to squeegee it after every shower. Once in a while, use Restorex to cut back any deposit. This is easy, if done once a month or so.
If you want a sample and have a try, please contact us from this site.
Restorex sells for a fraction of another product, currently promoted on Radio & TV to remove water spots.
We have a client on bore water having used it on the tiles in the shower, where the mineral deposits where a problem. Nothing would remove the residue. Restorex did it with ease and the client has already ordered some more from us
