Mr. Rattus and I are also environmentally friendly and so don't use anything containing detergent. We use laundry soap (don't know the brand name - Mr. Rattus buys it and actually does the laundry) and a peroxide rather than chlorine type bleach. We buy bottles of environmentally friendly fabric softener and soak towel strips in it. When they dry, you use them like a disposable fabric softener strip without the addition to the landfill. For heavy duty cleaning I use something called Nature Clean Oven and Barbecue Cleaner, which is composed of citrus and salt and is completely odor free and non-toxic. I bought a bottle a few years ago because the standard oven cleaners are just vicious chemically, and I found that Nature Clean actually did a better job than...I can't remember the name of the popular oven cleaner. I now use Nature Clean for all cleaning jobs where grease needs to be cut (fingerprints on the kitchen cupboards and soap scum in the tub, for example). All other cleaning is done with vinegar.
Since chemical based cleaning products are linked to asthma and other lung complaints, and I know for a fact that they cause my very mild asthma to act up, I can't imagine ever going back to them. Not to mention that all this crap is ending up in the water supply that we and future generations have to live on.
