pet urine / odor encapsulation

[encapman]

I'm getting a portable for the hopefully few times I need to extract.

That is the best way to go. You will occasionally still need to extract. And this is a situation where a good flushing would be the proper approach.

You could saturate the spot with a strong mixture of Encap-HydrOx and then extract thoroughly. You could also add Odorcide or Tea Tree oil to to your detergent to handle any possible lingering odor. Tea Tree oil is available from most drug stores and it's very effective in treating urine odors.
