We bought a bag of FOCA last night ($3.22 at Walmart) for enough that will probably last us 9 months or so. I was surprised that it was blue in color, for some reason (probably due to the packaging) I thought it'd be white with blue dots.
Anyway, we used 75ML of it to wash some dog beds this morning. It suds up some, but rinsed out very well on the second rinse.
50ml would probably be the perfect dose for us. It does dissolve very easily in warm water. While the detergent does have a rather strong scent, it doesn't stick to the clothes as noted in an earlier post. In fact, the dog beds are very clean and bright and they have no detergent scent at all after being washed with FOCA.
For the price, it can't be beat.
One last question, does it fade clothes rapidly? We plan on using it for our whites and colors, and use Cheer powder for our darks and denims.
