You're not the only one that thinks stain pro is pants. All it's ever done for me is cause light patches around a stain that wasn't removed. Likewise with RedRX.
My no.1 spotter is a servicemaster product, works on 99% of any spots that are still there after extraction.
I tried solutions RX and special spotter and didn't get on with them for various reasons.
Not really done the rounds of every other manufacturer's spotters, haven't needed to
