Excellent product but does not remove marker stains or completely remove blood stains. Even after soaking for days in a bucket Combined with Clorox 2, makes the best hand cleaner ...EVER! and is very gentle on the skin. I gave it four stars because it is a little pricy for the amount given

Removes most stains on first try

The jugs look in the images to be a gallon size, which is what I am used to in a refill. look at the description carefully for the number of ounces... the funnel included was great and really helped in refilling! While the jugs were smaller than I expected, they were a good bit more manageable in refilling the handhelds.
