My little one peed on the carpet. I’ve had the carpet professionally cleaned since then. I cannot smell urine.I pulled out a black light and was dismayed to see lots of spots on the carpet. Can a urine stain on carpet be cleaned successfully enough that the evidence is no longer visible with a black light? I’ve tried tons of Nature’s Miracle on the carpet, but I’m still seeing fluorescent residue after the solution has dried. I’m now going to try vinegar/water with a shop vac. Is it reasonable to assume that the stain will no longer be visible with the black light once the carpet dries? Thanks.
