It's not new. The blue and yellow can is about as familiar as anything I remember from my childhood. Banished to a shelf in the garage, I assumed WD-40 was for cars. Boy was I wrong! WD-40 is amazing. And cheap. A 12-oz. can is just $4.47 at Home Depot.
Here's the WD-40 rule: Use it, then remove it. Some say that a buildup of WD-40 can cause its own sticky mess over time. It's a petroleum-based product (so is Vaseline), and while the aerosol propellant is flammable, the product itself is, according to the manufacturer, harmless to humans.
WD-40 gets things unstuck and a lot more. I know. I go through this stuff like it's water.
IF IT'S MELTED.
Have you ever opened the dryer to find a crayon has ruined the entire load? The folks at Crayola offer this remedy for fresh heat-set crayon stains:
1. Place the stained surface down on a pad of paper towels.
2. Spray with WD-40, let stand a few minutes, turn fabric over and spray the other side.
3. Apply liquid dishwashing detergent and work into the stained area, replacing toweling as it absorbs the stain.
4. Wash in hot water with laundry detergent and Clorox 2 or Biz for about 12 minutes (use "Heavy Soiled" setting if there is no minute timer on your machine) and rinse in warm water.
5. Be sure to clean the drum of your dryer to remove any remaining wax residue. Spray a soft cloth with WD-40, and wipe the drum well. Run a load of dry rags through a full dry cycle.
IF IT'S STICKY.
Removes stickers and adhesives from glass, plastic, countertops and containers. WD-40 also removes chewing gum, tar and Silly Putty from most surfaces. Spray, wait, and wipe. Clean the tracks in sliding windows or sticky drawers to make them glide (spray on, and then wipe off).
