Things You'll Need
Baby oil, olive oil or vegetable oil
Grease-cutting dish soap
Wear safety glasses and gloves when using solvents.
Work in a well-ventilated room when removing stickers with solvents.
Do not use abrasives on porcelain, as you may damage the surface.
Porcelain has many uses in a house. Manufacturers make mugs, tiles, vases, toilets, and many other products from porcelain. Molding and baking ceramic at high temperatures in a kiln creates porcelain. After the porcelain cools, manufacturers add a glaze that protects the ceramic and makes it shiny. Price stickers or manufacturer details with adhesive-backed paper or plastic are often difficult to remove. If you can peel away the paper surface, it leaves a sticky adhesive residue on the porcelain.
Pour white vinegar into a pan, and place it on the stove to warm it. Do not bring it to a boil.
If the porcelain piece is small enough to handle, lay paper towels or clean rags on a flat and level work surface. If the porcelain piece is large, lay rags or paper towels around the sticker.
Dip a clean rag or sponge into the warm white vinegar. Dab at the sticker, and squeeze vinegar directly onto the sticker. Lay the vinegar-soaked rag or sponge over the sticker, and allow the vinegar to remain on the sticker 20 to 30 minutes.
Remove the rag or sponge, and peel off the sticker with a plastic scraper. If any adhesive residue remains, repeat the process to dissolve the adhesive.
Apply one of the following oils to the sticker: baby oil, olive oil, corn oil or vegetable oil.
Allow the oil to soak into the sticker for 15 to 20 minutes.
Scrape the sticker off the surface with a plastic utensil or scraper. If any adhesive remains, repeat the process.
Wash the area with a grease-cutting dish soap, and rinse well with plain water. If the sticker was on a surface that you walk or stand on, wash the area two or three times to remove the oily residue.
Apply a commercial adhesive solvent, or use acetone or turpentine on the sticker.
Allow the solvent to soak the sticker for 10 to 30 minutes, depending on the solvent and sticker.
Scrape the sticker off the porcelain with a plastic scraper.
Wash the area with a mild detergent two or three times to completely remove the solvent. Rinse well with plain water.
