I'm pretty saddened by this whole drama thing the past while. I've given Code Red a try the past while and like it just fine, and been told it contains no optical brighteners and nothing that would harm carpet.
I'm naive as h*ll and I tend to give everyone the benefit of the doubt, so when I hear this stuff about a product description changing I can actually buy the whole "It was improperly described on the website before" narrative. That's not surprising to me, sh*t happens and people make mistakes. It doesn't have to be a conspiracy theory or a malicious thing to blatantly obfuscate or deceive.
Just because something lightens up under a UV doesn't mean it has an "optical brightener" which can cause the kinds of damage to fibres like the old school OB's used to do. Urine lights up and no one here would call that an optical brightener in the same sense as an old school OB. Definitions matter.
Having said all that I want to know the actual results of Rob's Top 50 pre-spray tests

I'm too lazy to do all that heavy lifting myself but for years I've used the same products and I would love to know how they stack up to the others in his test. I'm also holding my breath for TMF to ship to Canada so I can try out these great products for myself.
Maybe I just wish we could all get along lmao
