Hello, Kerry here! I'm still trying to make good on my promise to post one household DIY and one craft idea per month. Maybe I'll be back on track by the end of the month? I wouldn't recommend holding your breath. This month, rather than one homemade household item, I'm going to post some different things most homes would have, and some unique uses for them. I love these life hacks. ;-)
Toothpaste (non-gel): remove crayon marks from walls, remove garlic or onion odors from your hands, buff a DVD, defog swim goggles.
Nail Polish: secure a loose screw, stop costume jewelry from tarnishing, repair a small hole in a screen, stop a runner in your pantyhose/tights.
Dryer Sheets: deodorize shoes, soak in a pot/pan with baked on food to help loosen it, remove soap scum and mineral deposits from the shower, tame flyaway hair.
Hand Lotion: polish shoes, remove static cling from clothing, tame frizzy hair, use it as shaving cream.
Petroleum Jelly: remove water marks from furniture, soothe dry and cracked paws on your kitty or puppy, treat the threads on your outdoor light bulbs to keep them from sticking, put around your nails before polishing them to help clean up mistakes.
Salt: wash green leafy veggies by swirling them in a bowl of salt water, rub salt water on the inside of your windows to keep them frost free, clean a greasy pan easily, clean up a sticky iron.
Chalk: clean up ring around the collar, stop tarnish on your silverware, hide a crack in the paint on your walls, keep ants out of your house.
