We live aboard and have switched all of our products to the Mellaluca lines... the cleaners are fantastic and 100% safe and biodegradable.
FYI... this is no longer a multi-level marketing program. You can just buy the products. They have a "after shower" spray that we use and there is no cleaning of any kind of residue inside the shower to worry about. Their liquid soap/body wash is excellent.
With kids or grandkids, all of their products are safe enough to drink. The whole line is great and comes to about 1/3 or 1/4 the price of off the shelf cleaners as they are mixed up in their own bottles from concentrate, so the space savings is also an outstanding side benefit. We live on a fresh water lake, and with all grey water going into the water directly, it's nice to know it is environmentally friendly.
Again, it is no longer MLM.
