I have done the AA treatment twice, both times following the instructions precisely in this link:
Both times the iron stain has started to return within a week. It's not returning as heavy as it was originally, however I can start to see my main drain discoloring slightly and I'm sure it will continue to get worse.
Does anyone have any specific products they have used successfully or any other methods they have used?
I have seen some of you mention Jack's products here. Are they worth the money?
Any help would be greatly appreciated as I'm very frustrated with this.
