Removing scratches with toothpaste???
I post at this other board and someone was asking about removing scratches from their eyeglasses. One person suggested toothpaste and even said she had used it.
I can't imagine toothpaste would do anything good for eyeglass lenses! Even basic plastic lenses without AR, I wouldn't think it would work well at all. Has anyone heard of this or tried it? It just sounds so wrong.
On the buffing wheel??
I could work. It is a finer abrasive than the polish we use (I think).
I think it would leave waves from the buffing wheel.
I don't know how well hardcoats will buff.
If you were to do it by hand, then it would take a week.
How about that, I had absolutely nothing to offer:hammer:.
Shouda keep my fingers shut.
It's amazing what you find when you google stuff. I discovered this thread where people are talking about how to remove bad ARs. Several people said they would never get it again, which is a shame.
One man said he got some internet glasses and the AR got all scratched up after 5 months. He swore he would never get AR again. So he has some glasses with a $5.00 AR coat and he decides all AR is bad.That cheap stuff that scratches and crazes and is horrible to clean turns so many people off AR.
Anyway, many people said they had good luck removing the AR with Armour Etch. They said you can get it from Micheals. I thought that was interesting. We used to have some AR remover that worked great. I think someone cleaned out the lab and threw it away. :( It said not to use it on poly, though.
Armour Etch is a glass etching cream. I wouldn't use it unless I was trying to opaque a lens!
If you use toothpaste or any other snake oil scratch remover on a lens, you're bound to remove the scratch resistant coating, at the very least. This means the lens will scratch easier. Worst case would be causing waves. Not that you'd cause waves very quickly with toothpaste...
Most toothpaste contains aluminum oxide (white rouge) so I guess that you could remove scratches from lenses. It might take you twenty hours or so even with a power buffer. You would also create a new multifocal lens with a truly unique set of parameters.
We actually have really good luck with the Armour Etch...we do it very rarely, but it works. Takes between 5 and 8 minutes, takes it off with little fuss, although it's nasty gritty and smells like chlorinated old socks. It doesn't opaque the lens at all, or at least not so anyone notices. We do a one-time warranty for scratching, and after that, removing the A/R is the only thing we can do.
That would be a true free-form!!:cheers:Originally Posted by rbaker
