Wheelbarrows
Seeing as wheelbarrows are typically kept outside, they tend not to age too well. They become worn and rusted over time and look like they attacked by some kind of termite colony. To combat this bleak outcome, spray some WD-40 all over the wheelbarrow to keep it from rusting.
Tape Marks
Moving into a new place is very exciting, you get to personalize it and decorate it however you want to. You can tape posters to the walls and do pretty much whatever you want with the space! The only problem is when you want to take down the posters or are moving. Tape typically leaves behind residue on the walls. To clean it up, spray some WD-40 and wipe the glue away with ease.
