You can't, I've destroyed mine and installed PEI.

Stick it down with this stuff here:

When you use this stuff you just wipe it with rubbing alcohol to clean the surface. Then it gives you near perfectly smooth prints where it touches the surface. The prints pop off easy after it cools but holds tight when it's warm. Personally I find it a waste of money to buy glue sticks/hair spray if you don't have to. Although I did buy glass I never installed it after this worked so well. It's amazing stuff and you'll never have to replace it.

As a bed plate, its frickin amazing stuff.

Do some youtubing and googling. Never need glue or hairspray again.

Not OP, but I got this - https://www.amazon.com/gp/product/B00QQ5Q3BI look for something similar/same size.

I ended up getting this and m3 tape too. https://www.amazon.com/gp/product/B01KBGJU5S

Is this what you use? https://www.amazon.com/Gizmo-Dorks-Printer-Surface-Polyetherimide/dp/B01KBGJU5S

I bought a pei sheet off Amazon and just clamped it on top of the original surface. No need for glue or hairspray or anything like that. It sticks perfectly and when it cools down it pops right off.

Would recommend it to everyone.

Don't use glue sticks, use nothing or just use hair spray, it's much easier. Both suave and aqua net have worked for me. You also don't need to use windex, just use alcohol, and you don't even have to clean it every time.

Seriously though as great as glass is PEI is just so much easier to deal with. This is the one i have, but you can also buy them from Prusa (which is what I am going to do next time I buy one).

Also, save yourself some headache and buy one of these:

I have this one.

I just have it attached to the bed with binder clips. Don't forget to re level the bed before printing.

I've been printing pretty much non stop on mine for a month and have not needed to replace it. I just wipe it down with isopropyl alcohol between each print. I've heard you need to give it a quick sanding with 1000grit sandpaper every few months. Unless you scratch it really bad or crack it, it should last more or less forever.
