Dirty grout lines between the tiles in your bathroom or kitchen can be a pain to clean. But all you have to do to keep them clean naturally is to use things you already have around the house. Pour hydrogen peroxide into a spray bottle and saturate the dirty grout. Let it sit for a few minutes, and use an old toothbrush to loosen the dirt, stains, mold or mildew. Wipe it up with a damp microfiber towel to reveal freshly clean grout. If you have stubborn stains, try a DIY paste made from white vinegar and baking soda, and use a brush to scrub away the grime.
The next time you're shopping at the grocery store, consider picking up a bottle of castile soap, a liquid soap that's made entirely out of vegetable-based ingredients and is 100 percent biodegradable. The eco-friendly soap has myriad uses beyond hand-washing; because it cuts through grease and dirt (without chemical sudsing agents), you can do a lot with it to keep your house sparkling clean. A few drops in a bucket of water creates an ideal floor cleaner. It also works well to lift stubborn stains set in clothes before washing them in the washing machine; it's great for degreasing pots and pans; and it can even be used to effectively and gently wash fingerprints off almost any surface.
It used to be that the bottle caps on top of plastic juice, milk and water bottles had to be removed and discarded before placing the bottle into the recycling bin. The reason? The plastic caps are a different type of resin (a No. 5 plastic), which is different than the more commonly recycled No. 1 and No. 2-marked plastic bottles. But today's modern recycling technology has made removing the cap obsolete. The bottles and caps are ground up and flaked; when the flakes are placed in water, the Nos. 1 and 2 plastic resins sink, and the No. 5 plastic floats, which makes separation a breeze.
