Wanting to know what washing powders are safe to use as grey water or if it is only the rince cycle?

Answer 1

Read the label of products sold in the organic section of your local market of in the health food stores. I think the company name that is avaiable in my area is Seventh Generation.

You can skip the soap and use either baking soda or borax for loads that are not deeply soiled, like sheets.

Maybe check resources from Mother Earth's News.
