Freshen up your tile grout with this product from Home Depot for under $15.  Your grout will look clean and new and you can even change the color of your grout.  I paint (or hire my daughter.....read on) my kitchen grout every couple of years.  I used a carpet-cleaning company once, but my 13-year-old does a neater job at a quarter of the price!  It's a great project for a teenager to earn money and be helpful around the house.  Use a foam, angle-tipped brush and be sure to test the color first - there are many to choose from.  

Monkey Hooks are my new favorite hardware product!  They hang photos and art (up to 50lbs) in drywall without tools and without damage to the wall.  Wall decor goes up in seconds - no exaggeration!
