Type of odor removal (edit, I took out disinfectant) to use, for rat urine smell

I have a 300 sq. foot crawlspace (3 foot high space to work in), where rats got in. This crawlspace had insulation between the floor joists, which I have all pulled out. It has been vented for the past month, but I can still not get rid of the rat urine smell.

The next step I am going to take is spray the underside of the floor, and all joist with a odor removal. Couple choices I have is to use a dry fogger, or spray it on with a 1 gallon sprayer.

I am having a problem in deciding on what odor removal to use. CDC suggest bleach, but does anyone else have a good idea on what product I should use.

Thanks beforehand

I was going to say bleach/water mix. Been using this for many disinfectant at home such as floor, door mat, washroom, etc.

Can't think of it now but there's cleaning stuff for that. Some enzyme based though some say white vinegar (usually 5 but can be 7 or 10% acetic acid) works too.

Best enzyme cleaner for pet messes including vomit, urine and feces.
I would use the enzyme cleaner to get rid of the smell, then disinfect to make sure it's germ free.

There’s a difference between disinfectant and odor removal. You may need to think about both, although disinfecting a space that nobody spends time in may not be as much of a priority.
