I know it sounds strange but it is a water displacement formula so it does well for cleaning things as well as loosening rusty bolts.
Here are a couple of things you can do:
1. Make coffee and tea stains disappear. You might think it strange to use WD-40 in the kitchen, but a little squirt can remove stubborn coffee and tea stains from your countertops. All you have to do is spray it on the stain and wipe it off with a dampened sponge or cloth.
2. Restore your refridgerator to its former glory. While cleaning your kitchen, take a look inside the refrigerator and try not to cringe at all the caked-on food bits. After emptying the contents, spray a little bit of WD-40 on dirty areas and wipe away. Just be sure to give the refrigerator interior a complete wipe-down before putting the food back.
