[header] How to remove marker from wood [title] Get a tube of regular toothpaste. [step] You want basic white toothpaste. Not gel, whitening paste, or anything with abrasive crystals in it. <sep> (A) The best brands for mark removal using toothpaste are permanent markers. However, the acids produced by these brands might be too harsh on a wood stain. (B) [substeps] Cream or oil is the best for rubbing off marker, so it should blend and be quite effective. Cream toothpaste is considered a good choice, as it doesn't have harsh chemicals (even though it's pricey) and it won't be as sensitive. (C) The traditional white paste will do the trick without damaging the wood. [substeps] Sometimes rubbing alcohol or peanut butter can be used in place of toothpaste to remove marker stains, but toothpaste is usually more effective. (D) Shiny, matte, or even painted or stain-free toothpaste is also acceptable. [title] Get a bottle of colored toothpaste.
