Apply hairspray liberally to stain. Rub with a clean dry cloth and the ink usually disappears. This works exceptionally well on polyester and polyester blend fabrics. Or, try rubbing alcohol on the spot before laundering. Check first for color fastness.
Club soda works wonders on removing grease.
Sponge with a cloth dipped in club soda, working from the outside edge toward the center of the stain. For linen and cotton, dampen a cloth with peroxide, lay it on the scorched area and iron with a warm iron. Spray new canvas or rope-trimmed shoes with a fabric protector to keep them looking new. To clean rope-trimmed canvas shoes, rub with a toothbrush that has been dipped in rug shampoo. Keep new white tennis shoes looking new by spraying heavily with starch.
