Pour down the drain. If a product is water-soluble (meaning you can mix it with water) you can flush it down a toilet or pour it down the kitchen drain with running water. Several water-soluble cleaning products are: liquid laundry detergents, chlorine bleach, liquid fabric softeners, multipurpose cleaners, glass cleaners, disinfectants, carpet cleaners and floor cleaners.
IMPORTANT: DO NOT MIX TWO OR MORE CLEANING PRODUCTS!!! We don't want to find your home on the five o'clock news. Secondly, if you have a septic tank do not use this method of disposal. Most septic systems are not capable of treating chemical waste.
Place it in the trash or recycling bin. If container is not empty please put in a plastic bag as to not contaminate other garbage. Several products you may want to throw out are: scouring pads, aerosol cans, remoistened towelettes, and fabric softener sheets.
Last but not least: Take to waste-disposal facility. Some products are way to hazardous to dispose of any other way other than in a waste-disposal facility. Such products include: flammable products, crystal drain openers, dry-cleaning fluid, and polishes & waxes that harden on surfaces.
