To remove sticker residue from a washing machine, use a paper towel or cloth soaked in vinegar to wipe out the detergent and bleach dispensers. Alternatively, you can use baking soda following similar steps.
You can also try rubbing alcohol or any oil, such as vegetable oil, to remove the residue. Delicate and dry-clean-only fabrics may require special care when using cleaners. For more soak a cloth in alcohol and lay it over the residue for several minutes before rubbing it off.
Additionally, BHG suggests using rubbing alcohol and vodka to lift off residue from any surface, while Modernly Morgan suggests ironing the residue area on a shirt. Be sure to test any cleaner in a small area first to prevent any damage.
