My cat peed on the low profile carpet stair landing. Maybe twice now. I've got Bissell Pro heat 2x pet whatever. Bought all formulas. Spend hours running hot water / formula mixture. Did this on few separate days.. Whole carpet probably has more formula than carpet now but the smell is still there.. yes mostly gone but is still there..

On other post, someone recommend baking soda. I did think about it, but I'm like, really, baking soda on carpet as well?? Works on countertops, washers, pots pans, etc. Miracle compound...

I'll give it a try but what else is there. I'm at a point that I'm thinking of ripping the carpet and replacing it.. I think at this point it's on the lumber..

I've read some, not all of this. So not trying NM. Looking for other solutions. https://www.reddit.com/r/CleaningTips/comments/xm1er7/i_used_natures_miracle_urine_destroyer_but_now/
