My mum has a stain from a dry-erase marker on her mattress. Anyway to get it out?

Question

We tried plain soap and carpet stain remove. any other ideas?

Answer 1

Try rubbing alcohol. Blot it with paper towels.
Alcohol is the best solvent since it doesnt stink unlike paint thinners. The stronger the alcohol, the better. Rubbing alcohol is only 70% isopropanol , so it may be a little weak. In your dads garage, he might have some stronger alcohol such as denatured alcohol or some other solvents.for cleaning car engines.

Answer 2

Use Rubbing alcohol 1/4Th cup of alcohol to 1 cup of water,and a squirt of dish detergent. that should do it. If it is still there the Plan B Ammonia put a little ammonia in water and scrub,
