- Homemade laundry detergent doesn't work very well. I stirred the goop. I doubled the amount used - my white cotton socks are so grey and ugly that they look like rags for cleaning the car.
- The homemade laundry soap doesn't dissolve well in cold water (which is all I use) and often leaves goopy streaks on the washing.
- Fels-Naptha is made from petrochemicals and isn't very green. Probably shouldn't go on the garden, either.
- Borax, while a naturally occurring mineral, is bad for your vegetable patch in greywater as it can accumulate in the soil.
