Candle Wax | Chewing Gum | Nail Polish | Rust
Spread brown paper (such as grocery bag) or a terry cloth towel over the area and iron with the setting on warm. The wax will be absorbed into the paper or towel. Move towel frequently and repeat until there is no more transfer of wax.
Remove any remaining traces of the wax with alcohol or dry cleaning fluid "Spot Shot®".
Freeze the gum using an ice cube, the shatter the frozen gum with a hammer or knife handle and vacuum up the shattered pieces.
Some citrus based products such as De-Solv-It® or Orange-Sol® have been demonstrated to break down the stickiness of gum so that it can be removed. Do not over saturate, since these products can destroy the latex backing on the carpet.
Remove as much of the nail polish as possible using a spoon or dull knife.
Apply a non-oily nail polish remover to a clean white cloth and gently rub (in only one direction at a time) or blot the spot. Continue until spot is removed. Do not allow nail polish remover to get to the latex backing. Go to the next step to remove nail polish remover.
Mix a solution of 1/4 teaspoon of clear liquid dishwashing detergent with (1) cup of water. Examples of safe detergents are Dawn® and Joy®.
Apply detergent solution directly to a white cloth. Dampen the carpet fibers in the stained area with the cloth. Avoid saturating the carpet. Wipe gently, turning the cloth frequently. Never aggressively rub, scrub, or use a brush. This may damage carpet fibers. If necessary, use your fingertips to work the solution to the base of the stain.
If spot is being removed, continue applying detergent and blotting with a white paper towel until spot is removed.
Wet the stained carpet fibers with clean lukewarm water to rinse. Cover the spot with an absorbent white towel or paper towel and apply pressure to blot. Repeat the rinsing and blotting procedures until all traces of the detergent has been removed.
If the stain is gone, place an absorbent white towel or paper towel over the area cleaned, and weigh towels down with a heavy color-fast object. Change towels periodically until carpet dries.
If there is still some stain on the carpet after following the previous procedures, then moisten the fibers in the stained area with 3% hydrogen peroxide. Let stand for one (1) hour. Blot and repeat until carpet is stain free. Light will cause peroxide to change back to water so no rinsing is necessary.
Follow the same procedure for removing nail polish, using lemon juice instead of nail polish remover. Let lemon juice set on rust for 5 minutes.
If this does not work, and it may not, call a professional. Most rust removers contain a very strong acid and are not recommended for use by homeowners.
