Every couple of months sprinkle a mixture of baking soda and a tablespoon of your favorite fabric softener over your mattress, let it sit for an hour, and then vacuum it up. Gets rid of dust mites and freshens up the mattress. Keep that same mixture in a small mason jar with holes poked in the top in your linen or clothes closet to keep it smelling fresh. - sublime decor
DIY Grout Cleaner: Just use Coke! Squirt some Coca Cola on the dirty grout (use an empty sports drink bottle or similar to squirt) and let sit for about a minute. Using an old toothbrush/grout brush/etc, scrub the grout. After scrubbing, wipe the mess up with paper towel or a rag. Remember to mop the entire area afterwards to prevent your floor from getting sticky!
