Protecting Wheelbarrows
Wheelbarrows are prone to creaking and squeaking, which can get a little annoying over time. All it takes to get rid of this problem is to use WD-40 on the thing. Even the people who use it as mere decoration will appreciate the tip because it will make the equipment that much easier to move!
Removing Tape Marks
What could be a better way to show off your interests and advocacies than by hanging posters all over your walls? This might be true, but posters also tend to leave sticky residue behind when you finally peel them off. It is a good thing that something as accessible as WD-40 will have them out in no time at all!
