So: SoapNuts work well!! (we tried them on darker/grey clothes, as they can leave greyish/brownish tinge..) YAY!!

Almost no smell, Mom took ‘em out when the washing machine stopped the washing cycle, & before the rinsing cycle began.

Clothie pads wash well with the regular load of white linen & the regular washing powder Mom uses… (They were rinsed & soaked in cold water, with salt added, immediately upon use. even those with no salt added initially, only later, washed well.)

I bought eco-friendly dishwasher detergents too (for the dishwasher & hand use), & soap (for hands or stains on clothes).

Next thing to test: if more eco-friendly washing powders work well too…
