I did it with the Nature's Miracle laundry detergent
. I used a plastic tub (like a dish tub) and poured some in, then some water, and just left the clothes in it for a while... I don't think I measured it out exactly for this... just kind of eyeballed it... but there's probably directions on the package.
If you can't find the laundry detergent, I use the Nature's Miracle For Cats
in my carpet cleaner. That gets diluted as well - usually I just pour some into the water container along with the water... don't really measure... maybe a half a cup or so? Either way you could use this one the same way I used the laundry detergent.
Come to think of it, I'm sure you could just use the NM laundry detergent as regular detergent... (which I'm sure is what it was made for
) but I soaked the clothes for a while before I washed them just to make sure it had plenty of time to work.
