Can common household products change or take away permanent marker? I want to know if the video made by Modernly Maid is true.


What does "permanent" mean? I looked it up in the dictionary.

I visited the sharpie website. Under FAQs, there is a section that tells you how to get marker out of things.

I wonder if this video is really true. Could these common products take off permanent marker? I used this video to help develop the idea for my Science Fair project.
How to Remove Permanent Marker from Everything

1. I do not think hand sanitizer will take permanent marker out of a shirt.

2. I do not think toothpaste will take permanent marker off the wall.

3. I do believe rubbing alcohol will take permanent marker off wood.

4. I do believe white vinegar will take permanent marker out of carpet.

5. I do not think a dry erase marker will take permanent marker off a dry erase board.


  • Shirt
  • Wall
  • Wood
  • Carpet
  • Dry Erase Board
  • Hand Sanitizer
  • Toothpaste
  • Rubbing Alcohol
  • White Vinegar
  • Dry Erase Marker
  • 4 unused toothbrushes


  1. Gather materials.
  2. Mark the shirt, wall, wood, carpet, and dry erase board with two large dots using the permanent marker. Make sure each dot is the same size and not too close together.
  3. Allow marks to completely dry.
  4. Apply hand sanitizer to the first toothbrush. Scrub the first dot on the clothing for 60 seconds.
  5. Apply toothpaste to the second toothbrush. Scrub the first dot on the wall for 60 seconds.
  6. Apply rubbing alcohol to the third toothbrush. Scrub the first dot on the wood for 60 seconds.
  7. Apply white vinegar to the fourth toothbrush. Scrub the first dot on the carpet for 60 seconds.
  8. Use dry erase markers to color over the first dot on the dry erase board.
  9. Observe results. Take photographs.

Data and Observations

Shirt vs. Hand Sanitizer

Wall vs. Toothpaste

wood vs. rubbing alcohol

Carpet vs. White Vinegar

Dry Erase Board vs. Dry Erase Marker


1. The hand sanitizer did not work to get the marker off the shirt. It just made the stain spread out. My hypothesis was correct.

2. The toothpaste did take off some of the marker on the wall, but not all of it. It left a dark shadow on the wall. My hypothesis was wrong and right.

3. The rubbing alcohol did not work to get the marker off the wood. It made a much bigger dark mark. My hypothesis was wrong.

4. The white vinegar did not work to get the marker out of the carpet. My hypothesis was wrong.

5. The dry erase marker did take off the permanent marker from the dry erase board. My hypothesis was wrong.

I think the Modernly Maid video is almost all incorrect information. The only test that worked well was the dry erase marker taking off permanent marker on the dry erase board. I have learned that not all commercials are true.

I know that if someone writes on my mom's white board with permanent marker, there is a way to get it off. I can show someone how to remove it very easily.

I also think that you should be very careful with permanent markers because stains are very hard to get out.
