Rather than buying those ridiculously expensive anti-slip mats for a rug, just turn it over and run a few lines of acrylic-latex caulk every 6 inches or so. Let dry and flip over and your rug wont be going anywhere!
This really works, amazing! My mother tried it with success and then told me, so I tried it too! :-) Great way to clean Oven Top Filters-- Boil a big pot of water, add a half cup of baking soda (but only one tablespoon at a time - it fizzes). Drop the filter in and watch the grease slide off. Rinse, repeat if desired (I scrubbed gently in some spots).
*Instead of using extra laundry detergent to pre-treat, turn to white chalk. Simply rub onto greasy stains and the chalk powder will absorb the grease, making the stain easily removable by the laundry soap in the wash. It might sound silly, but it has worked wonders for everything from lipstick to bacon grease.
