Hi! To clean LCDs we use Contact Cleaner (name of the brand) and microfiber cloth! If works perfectly. If you mean cleaning the LCD by removing the after polarizer removal glue, that's a completely different process!

Hi, If you want to test iPhones, you can use an iPhone tester and it gives more accurate readings than a box tester. To transform an iPhone into a tester, one end of the tester flex cable is attached to the iPhone and the other end to the screen being tested. Hope it helps!

You can use b700 glue or you can use preglued frames. If you decide to use preglued frames you will need a framing machine. We will be updating more info in our blog therefurblab.com ! Ask us anything!
