Much like warm water softens tape, heat can help melt stubborn adhesives without damaging the surface of your floor or wall. Just one minute with a hairdryer, heat gun or even a blow torch will do the trick. Gently scrape off the adhesive while you apply heat on the surface of your floor or wall.
If the tape resists, you can run a (utility knife) or razor blade along the edge to cut the paint seal. For added safety, you can also heat the tape with a (hairdryer) on a low setting to soften the adhesive before removal. This method minimizes the risk of peeling paint or damaging the wall.
Removing tape too quickly or at the wrong angle can cause the paint to lift. The best practice is to remove the tape slowly and at a 45-degree angle to minimize the risk of peeling.
Use a putty knife or razor blade to score along the edge of the tape. This prevents paint from being pulled up with the tape and from cracking along the paint line. Taking your time, lift up the painter's tape and pull it back on itself, removing at a 45 degree angle.
Just put a drop of WD-40 on the top edge of the tape, and wiggle it gently so it can get at the adhesive backing. Work drop by drop, gently pulling the adhesive away from the wall each time to make microscopic entrances for the WD-40 to wiggle in there and work its magic.
Removing adhesive: Chemical approach
One easy method is to use standard cooking oil or oil-based materials. Vegetable or canola oil can work wonders, as can peanut butter or mayonnaise. Spread it on, let it soak into the residue for about an hour, then wipe it away. For a tougher clean, try rubbing alcohol or vodka.
However, using this on your walls gets a bit tricky, so you need to make sure you are using it the right way. Goo Gone spray gel does not remove paint from walls. However, the manufacturer recommends that it not be used on unpainted drywall at all, so apply this only to painted areas.
Since the adhesive isn't as strong or sticky as it is on regular masking tape, painter's tape peels off residue-free and doesn't take any extra paint with it.
Use Heat to Get Stickers off Walls
If simply peeling the sticker off is not an option, you can use heat to help soften the adhesive. Take a blow dryer and hold it 4 to 5 inches away from the sticker. Keep your dryer settings at low to medium heat — too much heat can cause your paint to bubble or peel.
The first thing you need is a tape-in hair extension remover. This can be made at home by mixing alcohol and water to get a 91% alcohol solution. To achieve this alcohol percentage, simply take 99% isopropyl alcohol and dilute it with pure cold water in the ratio of 100 ml of 99% alcohol to 10 ml of water.
Automotive masking tapes, instead, will not damage the paint. Traditional tapes are difficult to remove and may leave unattended residues, while automotive masking tape is safe for car paint.
Improper Painting Surface Preparation
The painting surface needs to be thoroughly prepared before the paint job is initiated. When the paint is applied on an unprimed or uneven surface, it will start blistering and peeling. Proper prep work is a must if you want to avoid this.
Tape should be removed when it feels dry to the touch, which is ideally about an hour after painting. If it still feels gummy, leave the tape on overnight and remove it within 24 hours, when it finally feels hard and dry.

Final Word. This is how simple it is to remove stickers from your wall with WD-40 without damaging the paint. Apart from this, the WD-40 Multi Use Product can be used for lubricating door hinges, removing rust from metals, cleaning your vehicles, and a range of other uses.
Rubbing Alcohol or Vodka
Wet a paper towel or clean cloth with rubbing alcohol, and rub the residue to lift it off. For stubborn stickers, place an alcohol-soaked cloth on the area and let it sit for several minutes to soften the residue. Use the cloth to rub off what's left behind.

If you have recently painted your walls, this usually indicates that the paint has not fully cured. Stretching the tape as you apply it can also cause it to lift off of the wall. It could also mean that the surface was not properly prepared.

If using a spray bottle, try a 50/50 mix of water and vinegar, or if using a sponge, 1 part vinegar to 6 parts warm water should do the trick. No matter which method you use to apply the vinegar mixture, let sit for a few minutes before removing.
Goof-Off comes in a metal container and has a stronger smell. It cuts through most every kind of goo and paint for fast easy removal. However, it can damage certain types of plastics. Goo-Gone is a bit more gentle and is my preferred choice for anything plastic.
