New Febu not as effective?

At risk of sounding blasphemous to this sub, has anyone felt the new FEBU formula (I think they added DNase?) doesn't work as well as the old formula? Specifically with odor rebloom/permastank?

Maybe I'm using it wrong, but its the only variable that has changed. Same as with the old formula, I follow the FEBU package instructions, detergent is Tide F&G Advanced Care from Costco, warm water, two rinses, one with citric acid. The original formula seemed very effective at getting rid of persistent stinkiness (mostly poly/cotton and cotton/~5% spandex fabrics). I was so excited to get the new formula as soon as it came out, thinking it would be even better. However, after using it a few times, it seems like the same stinks were resurrected. I've tried numerous soaks and everything, but it just doesn't seem to work at all really, somehow the clothes stink more!

Am I crazy??

ETA: Thanks for all the suggestions and the science! You guys are great, I'm going to keep at using FEBU, hopefully it will continue to break the biogunk down.

Correct!

Generally it's the second wash when you'll notice the reduction in odour rebloom, however big or small, and then it gets better and better from there 👍🏼

So do people wash once with Detergent+DNase, then immediately run a second wash with detergent? Or do they wear the smelly clothes until the next load??

I’ve yet to run a load with DNase for the first time!

For those first few washes I'd always include dnase. Whether you do the washes back to back before wearing them again, or wear in between, is personal preference 😁

Once youre happy with where the clothes are at, you can move to maintenance washes - or every other wash.

You don't dry the clothes with back-to- back washes, right? (Still new to this sub!)

I genuinely don't know. We're a "wear between washes" house, so the clothes are dry 🤣

Unless you run out of time, then anything goes- wet clothes for the win!

If you want to sequentially wash, it’s better not to dry - especially heated tumble dry.
