How to clean the Sticky Side of a Screen Protector?

A screen protector helps protect your phone’s screen from scratches, cracks, and any other possible damage. To achieve its optimal performance, we need to maintain its adhesive properties. Fingerprints, dust particles, and residue usually compromise its adhesive properties, leading to reduced effectiveness and, in most cases, phone damage. 

8 Steps To Clean the Sticky Side of a Screen Protector

To clean a screen protector, you will need the following

  • Cotton swabs
  • Microfiber cloth
  • Compressed air
  • An isopropyl alcohol
  • A cloth without the lint
  • Soap or cleaning solution

Step 1: Remove the Protector from the Phone’s Screen

The first step to cleaning the screen protector is to remove it from the phone’s screen. Make sure to peel it off carefully and gently, starting from one corner. Once you have peeled it off the screen, place it on a flat surface with its sticky or adhesive side facing up. This method helps prevent various types of screen damages while ensuring your protector remains effective.

Step 2: Remove Dust and Debris

Before you deep clean the sticky side of the screen protector, remove any loose dust or debris from the protector. You will need to apply pressure on the affected areas. Removing dust is important to prevent scratches when cleaning.

Step 3: Make a Cleaning Solution

Grease from the protector can be removed using an isopropyl cleaning solution. This solution is made by mixing equal parts of distilled water and isopropyl alcohol. Water is added to dilute the alcohol, as it may leave marks on the protector.

Step 4: Wipe with a Microfiber Cloth

Clean the screen protector adhesive by gently wiping it on the sticky side. Make sure to move it in a circular motion to ensure it covers the entire area. This will remove any fingerprints or smudges from the surface. You can use the cotton swab for the same purpose. Just ensure you do not apply excessive force, as it can compromise the protection.

Step 6: Use Liquid Soap for Persistent Stains

Persistent stains may not go away easily with isopropyl alcohol. Free soft cloth kept in a small amount of mild liquid soap can work great in this case. Use this cloth to wipe away any stains on the protector. Don’t forget to dry it with another piece of dry towel.

Step 7: Dry the Protector

The cleaning part is done here. All that remains is to wipe away access moisture or soap residue on the screen protector. To clean the screen protector, Use a lint-free cloth and gently wipe it all over. Compressed air can also work, in this case, to blow away the moisture.

Step 8: Reapply the Screen Protector 

Carefully reapply the tempered glass screen protector on your mobile phone once it has dried completely. Take your time applying it from one side to another. Be very careful that you do not misalign it or catch any bubbles during the process. To achieve the proper adhesion, push the surface carefully.

Additional Screen Protector Cleaning Tips

Take care of the following points to ensure optimal performance of your screen protector for the longest time:

  • Keep your mobile phone away from direct sunlight, heat, or moisture. Exposing the phone to harsh temperatures can affect the screen protector’s adhesive properties.
  • Wipe the screen protector regularly with a damp microfibre cloth to remove fingerprints and smudges.
  • Do not touch the sticky side of the screen, as it can transfer oil and debris to the adhesive part.
