- Use any method to get steam in a room. A suggestion is a hot shower, which fills the room with steam. When the steam has subsided, there will be less dust in the air than usual. This is the best time to apply the screen protector.
- Use a cloth to remove most of the grease and dust from the screen. Save getting your microfiber cloth dirty. You want to remove as much dust as possible, especially if it just came from the factory packaging.
- Lay the microfiber cloth on the screen to keep the dust off.
- Prepare the screen protector.
- Remove the cloth from the screen, align the protector, and place it on the screen.
- Using a credit card (as a scorer), carefully remove all the air bubbles.

Another method:
1. Pick out a good protector. This means that it should be thick, and probably not the cheapest. This becomes especially important with portable video game systems, which are plagued by sub-par peripherals. I like
Boxwave,
Invisible Shield, and
Power Support.
2. Be careful with the protector as you take it home. One of the main reasons that a protector doesn’t apply well is that it becomes lightly bent, and won’t adhere well. Be sure to keep it flat until you’re home.
3. Prepare your workspace. The biggest key ingredient here is a flat space with lots of light. Light is critical so that you can be sure to spot any flecks of dust in advance. I like to lay down a shami on the table. Shamis are well suited because they are soft, water-absorbant, and don’t generate lint nor hold much dust.
4. Wash your hands. before you start the process, make sure your hands are clean.
5. Clean the device. I recommend using glasses cleaner and special lens cleaning cloth. You never want to use a towel during the process, since it will leave little bits of cloth and don’t wipe away evenly. You should probably go through cleaning the device down twice to be certain everything is clean. I recommend using a small circular motion with the cloth.
6. Blow away any dust. Use a can of compressed air and blow away any small bits on the surface of the device. Be sure not to shake or hold the can upside down, as that can shoot the liquid onto the screen. IF this does happen, just wipe it back down. Really examine the device under the light from different angles and be absolutely certain there is no dust on the device.
7. Remove the screen protector. This is when you remove the screen protector’s protective film in advance of application. be careful to not nick the protector with your fingernail when you’re removing the film cover, since this can cause it to not apply evenly. Once the thin film is removed you should be very careful to not touch the side that will be in contact with your screen, since it will absord and oils or grease on your fingers and ruin the clean application.
8. Spray down the protector and surface of the device. This is perhaps the least well-known step in applying a screen protector. You should spray both the device and the protector (the side that will be in contact with the device) with the glasses cleaner. You don’t want to over-douse each piece, but you want a good layer of lubricant on each. The liquid layer helps with alignments and making sure there aren’t bubbles.
9. Apply the protector. Be careful to line it up well with the device. When you have it aligned, you should have enough liquid between the two pieces for the protector to float on the device, which should give you the chance to adjust it a bit. Now you should take a credit card and squeegee away the liquid. Be careful to hold it in place at the starting point so the squeegeeing doesn’t cause the protector to slide around. You have to be very thorough at this step to make sure you are getting all of the liquid out.
10. Let it sit. That’s it! If you worked carefully and took your time you shouldn’t have any bubbles. However, there might be a bit of liquid left that needs to evaporate, so be sure to let it sit for several hours. It may take up to a day for it to be completely set.
