No I hear both you on that,,I'm not about to go back and start buying their 'snake oil'. I wanted take it there as a cross check to make use my little test kit is accurate. (there's a standing order in our home, "do not buy anything")

Now that were starting to make some progress,(the stain is fading to almost unnoticeable) (just still hard to tell fully with the water being so milky) We now have some renewed confidence so it's much easier to be patient .

Thanks for all the help...I'll keep posting as we progress.
