Crayon marks have a way of showing up where you may never expect them, such as on your favorite leather chair. Instead of trying to remove the marks with harsh chemicals or hiding them under throw pillows, treat the waxy scribbles with heat or gentle household materials that are safe on many types of leather. When in doubt, test your chosen cleaning material on an inconspicuous area first, as some leather finishes are more delicate than others.
At Your Fingertips
Since crayon marks contain a waxy residue, some of it may be thick enough to remove by hand -- or by fingernail. Rub your fingernail gently over the marks to scrape the crayon away. Keep a paper towel handy for wiping off the loose residue. Continue scraping until you've removed as much as you can. If you'd rather not use your fingernail, scrape gently with the bowl of a plastic spoon. Scrape just enough to abrade the wax without digging into the leather, as too much pressure may damage some leather finishes.
Help From Hot Air
A hair dryer helps soften and melt crayon wax so you can lift it from the leather -- no chemicals needed. Set a hair dryer to a low or medium heat setting, holding it 6 to 8 inches away from the crayon marks, moving it slowly and continually. After a minute or so, move the hair dryer aside and blot the melted marks with a folded paper towel. Apply more heat if none of the wax comes up, moving your hand out of the way first. Continue alternating the heat and blotting treatments until you've removed all the wax.
A melamine foam eraser -- the type designed to clean soap scum, scuff marks and buildup from all types of surfaces -- can remove crayon from leather as well. Wet the corner of a clean melamine foam eraser, squeezing it gently to release excess water. Gently rub the crayon mark, working from one end toward the other, rather than vigorously scrubbing across the crayon. Continue until the crayon is gone. Test the eraser in an inconspicuous area, such as the back of a leather sofa, before using it on the crayon marks.
Clear Crayon Remover
Dab a small amount of rubbing alcohol onto the remaining crayon marks with a soft white cloth, wiping from one end of the crayon to the other. Apply a little pressure with the cloth wrapped around your finger as you wipe the stain to help remove the wax. Afterwards, rinse the cloth. Stir a squirt of dish soap into a bowl of warm water, dip the cloth in it, and wipe the crayon-marked area once again. Follow up with a damp cloth using no soap; then wipe the area dry with another white cloth. Apply a leather protectant or conditioner afterwards to help protect the surface.
