We had a mouse in our SUV. How can we clean and disinfect the interior for a low cost?

We let our SUV sit for a while and there was mouse poop all over the rugs as well as some elsewhere. Oddly, none was found on the seats. We vaccuumed the rugs before we knew we weren't supposed to, but how can we clean and disinfect the vehicle interior without spending a fortune we don't have? Are there any cheap Dollar Tree products we can use or other low cost brands? We want to clean the carpeted floor and leather seats. Thank you.
