I have a pump-up garden sprayer that I pour a bottle of orange disinfectant in, Lysol or whatever, and add an equal amount of water, and spray wherever needs it. I wouldn't spray it on my car, though, maybe the ground around the tires. Seemed to work in a short time with no bad effects. I have several of these for insect spray, herbicide, deodorant, and Miracle Grow, and I tell you this; don't waste money on the 7-10$ sprayers, even the name brands. Get somethig like the 19$ RoundUp herbicide sprayer at Lowe's. The foaming nozzle attachment is very handy on these, and they are dependable. Had good luck with cheap ones in the past, but three in a row were useless with bad spray nozzles.
