In an effort to conserve water, I have been using my wash water on my flower garden. I'm concerned about the build up of soap etc. in the soil. In the past, I've used a Basic H product clothes soap but have found it to be just too cost prohibitive now. My machine is a front loader so it uses small amounts of low sudsing soap(found at my local retailer). The product label info is so confusing - any suggestions as to a safe, good cleaning, affordable soap? Also, is the water safe to use on my veggie garden? Thanks, Cleo.
