Removing Any Residual Marks

1
Dip the end of a Q-tip in isopropyl alcohol. Make sure the end of the Q-tip is completely saturated with the alcohol. The alcohol will be more powerful than the solution you used prior and it should only be used for spot treatments.
- Isopropyl, or rubbing alcohol, can be purchased at local pharmacies or convenience stores.
2
Wipe the mark with the wet end of the Q-tip. Only wipe the area with the mark. Use short side to side strokes, making sure to overlap with areas you’ve already wiped. Rotate the Q-tip as the mark starts to lift off of the screen.
- Be gentle with the Q-tip. You shouldn’t be pressing into the screen too hard.
3
Use the other side of the Q-tip to dry the spot right away. Don’t let the alcohol soak into the screen, or else it could leave a permanent stain. Dab the dry end of the Q-tip on the mark to remove the alcohol and any mark that is left over.
- You can also use a clean microfiber cloth to wipe the area dry.

Question

There are indents in my screen caused by roiled-up dirt. How do I roll my screen all the way down so I can clean right up to the roller?

It sounds like you may need to remove the roller to clean right up to it. You can remove the 2 screws on either side of the roller housing and then remove the cap. This will allow you to access the dirt.

Question

My screen was in storage and has an outline of a piece of furniture and what seems like spots of the stain of wood. How can I remove these?

Community Answer

You can try a mixture of 95% water and 5% dish soap to remove stubborn stains or stickiness. For those stains that just don't want to go away, you can try 409 or Greenworks too.
