Perhaps you have that blue and yellow can of WD-40 sitting on a shelf in the garage, used on occasion to free a stuck nut or bolt or lubricate a squeaky wheel. Well, it's time to bring that can into your house. There are literally hundreds of household uses for WD-40 including removing crayon marks from your walls and cleaning grease off your kitchen stovetop.

About WD-40

The exact ingredients in WD-40 are a secret, but WD-40 is a petroleum-based product with many household uses. It lubricates, cleans and protects, keeps out moisture from tools and other items, and much more. WD-40 is available at most automotive, grocery, and hardware stores.


Surprising Uses For WD-40

WD-40 was developed in 1953 and stands for "Water Displacement, 40th Attempt." It was developed for a rocket company in San Diego as a rust preventative and degreaser.

Uses for WD-40

WD-40 is safe on almost all surfaces found in your house. The few exceptions include some plastic surfaces that must avoid contact with petroleum-based products. The main household uses of WD-40 include:

  • Cleaning
  • Protection
  • Penetration
  • Lubrication
  • Moisture displacement

These uses translate into an incredible number of household hacks—easy fixes for annoying problems. For example:

  • Use WD-40 to remove sticky gunk from surfaces. You can spray WD-40 on your stove to de-grease, use it to remove glue from store-bought items, or spray it on surfaces to remove sticky materials such as clay, Silly Putty, or paste.
  • Use WD-40 to remove rings. Have you ever found it hard to remove a ring once you put it on? A squirt of WD-40 will do the trick.
  • Spray WD-40 on outdoor wear to make it water-resistant. Amazingly, WD-40 is an effective and low-cost way to make boots, gloves, and other items more resistant to water. Spray it on before you go out in snow or rain.
  • WD-40 can clean many surfaces as well as bleach—without the risk of discoloring. Use it in the toilet to remove stains, spray on surfaces to remove tea or coffee rings, and more.
  • Did you know WD-40 can be used as a pesticide and insect repellant? You can spray it directly onto insects to kill them or use it on surfaces to prevent insects from entering the house or building nests.
  • You may know WD-40 does a great job of loosening locks and bolts but did you know it can also loosen stuck-on decals, stickers, and zippers?
  • Because it lubricates, WD-40 can help to keep guitar strings, baseball mitts, and even garden tools from drying or cracking.
