Remove permanent marker from microfiber using the same techniques as with other upholstery. Gather mild dishwashing detergent, vinegar, rubbing alcohol and ammonia. These processes require allowing the solutions to saturate the stain for up to 30 minutes at a time. Test each solution on an inconspicuous spot of the microfiber before applying to the ink stain.
Use the first solution
Mix 1 tablespoon of the dishwashing detergent, 1 tablespoon of vinegar and 2 cups of water. Apply the solution using a white cloth. After 30 minutes, blot the spot with a clean towel. If it is removing the spot, but some ink remains, repeat the process; otherwise, proceed to the rubbing alcohol.
Remove with rubbing alcohol
Use a fresh cloth and rubbing alcohol to blot the stain. Once the stain is removed, rinse with cold water and use a dry towel to blot the moisture. Repeat if some of the stain remains.
Provide adequate ventilation before using ammonia. Mix a new solution containing dishwashing detergent and 1 tablespoon of ammonia in water. Use the same blotting technique as before. Continue to wet the stain and let the solution stand before blotting. Once the final traces of ink are removed, rinse off the ammonia solution using clean water, and dry the upholstery.
