Protection for acrylic glass vivarium against scrathes

[thurmant56]

What can I protect the acrylic glass with. I just received an 81 gal vivarium I ordered. My girls been in a 40gal. But this 81gal has acrylic glass. I need something to protect the glass from scratches that's safe for reptiles. Any advice would be greatly appreciated

I am not aware of any thing for those - the only thing I can recommend for cleaning them is Spray Way glass cleaner found at Home Depot and probably Walmart- I replaced one of my tanks w/ glass from Zen Habitats for a 120 gallon tank and one day opened it too hard and one of the doors shattered - the tanks came w/ the acrylic doors and I gave up after that happened so the tanks are back w/ the acrylic doors -
