Catch Dust in Air Conditioning Units
When installing an air conditioning unit, apply some WD-40 spray on the filter. This will help the unit catch dust, which in turn improves the quality of air in your home. But those with central air conditioners don’t need this.
Clean Poop From Shoes
You took an evening stroll. It was dark. You didn’t see it, but you certainly felt it when your shoe sank into a pile of dog poo. Don’t worry. Just spray WD-40 on the sole of your shoe and clean the poop from the crevices using a toothbrush. Then rinse with cold water.
