How to get dog wee smell out of clothes?

Dog wee'd on a pile of clothes I left in the corner. I washed them and they still smell quite strongly of it, especially the jeans. What else can I do to get it out? Can't really afford new clothes, so don't want to throw them away if possible.

Anon because I have friends on here, and I don't really want them to know this, cause its quite rank tbh. NOT Because I'm a troll. I know every single anonymous thread gets some sort of "troll" related response, but this is actually serious, actually happened, and I would like some actual help. People who want to call me a troll can **** right off.
