I was not thrilled with home pro. I have a neutral pH product made for us and private labeled. About 2.25 for 16 oz if I buy in bulk. Lots of them seem to have ingredients that cause a little color loss if overused.
There is a customizable Wool Pro spotter which has been approved as safe and effective for wool. Great give-away and marketing item for clients with rugs, fine fabrics and/or woll wall-to-wall carpet. Here is the link for info - http://interlinksupply.com/index.php?item_num=13624
