How to clean seats in a car?

Hey gals. What helps clean your vehicles car seats? We are starting to get everything ready for the baby and I can’t afford to get my car professionally cleaned but it needs a good scrub down and cleaning before baby comes. Any suggestions on what to clean your car seats (not the infant or toddler car seats) with to get the dirt and stains out?

oxy spray, a scrub brush, and good vacuum

They sell sprays/foams that help to pull the dirt out of fabric. You just spray it, wait for it to dry and then vacuum well. This won’t get it as clean as shampooing it. But it is cheaper. If you have like 50 bucks though, you can rent a carpet shampooer with the handheld attachment. A lot of lowes/ Home Depot and some grocery stores have them for rent.
