protect Plexiglas?

I now just how easily Plexiglas scratches, especially when you
try to use a rag and water to remove dirt. The dirt is like
sandpaper. My question, Is there anything I can spray on
Plexiglas so dirt will come off with just spraying water on it?

Thanks
 
Yup, pre-treating with Rain-X repellent before the dirt gets on it will help with that. But if you really want scratch resistance you shouldn't be using acrylic (Plexiglas) but rather polycarbonate (Lexan).
 
In between Plexiglas and Lexan is hard-coated, scratch-resistant Plexiglas. Glue won't stick to the coated surface. The coating in the area to be glued needs to be sanded or scraped off.
 
I have heard that the headlight cleaner for plastic headlights will remove scratches. It is worth a try but I would not use it in an area that you have to look thru until you are sure it works. I had some scratch remover I used on my snowmobile helmet face shield that worked
 

The plastics place I buy my acrylic sheets from sells a special abrasive cleaner that also removes scratches. Their sales people tell me to use nothing but this cleaner on the acrylic. I've tried water and soap and it ruins the sheets of plastic. After they told me about the special cleaner it;s all I use. It goes on like a liquid car wax or paste, and buffs off. Sorry I don't have it in front of me but a plastics place will know what it is.
 
Polish and cleaner for convertible cars rear plastic windows. We had a boss that liked drop top cars and a plastic door window between the shop and the showroom. The polish made that window look like a new one.
 
Meguiars plastic polish. When I worked servicing Float planes (just after the dinosaurs died out), it was used to take scratches and stuff off the plexi windows. HTH
 
On Aircraft canopies the tech data used to tell us to only use cotton cloth to clean them to prevent scratches. I think I would use one of the plastic cleaner/polishes and stick with 100% cotton rags

Yep - When the windshield on my old Vetter fairing got 'cleaning scratches' I would just polish it with Pledge - works pretty good on anything that you want to see through that's made of plastic. :)
 
If you have polycarbonate (Lexan) rather than acrylic (Plexiglas), polycarbonate scratches much easier and it's very difficult to remove scratches from polycarbonate.

I use car polish (Liquid Glass, if I can find it) on acrylic and polycarbonate.
 
No, if you remove enough material to take out a scratch you may change the optics of your lens. You might be better off to fill in the scratches with something. The best solution would be new lenses in your existing frames. Now-a-days Shopko and Walmart have good optical departments with decent prices, starting around $80 for a pair of bifocals and $40 for a pair of single lens glasses. Both will make new lenses for a prescription up to six months old.
 

I had a bud that ran a eye glass operation. I would stop by and have him run my glasses thru a ultrasonic cleaner every now and again. He would pull out a can with no label on it and clean the lenses. For awhile they were good as new are close so one day I ask "Whut's in dat can". It was Plexo he tore the rapper off it...

Try it you will like it on your glasses....
