Deep-Clean Carpet and Upholstery
Use a carpet cleaning machine to get the deep dirt that settles into the fibers of the carpet. (Clean cloth seats this way as well.) It sprays the carpet with a solution of water and cleaner and then sucks the dirt and grime into a reservoir. A machine like this pays for itself after just a few uses. You can also rent one from a rental center or use a spray-on cleaner and a scrub brush instead.

Ever notice that line of grime on the tops of windows when they're partially rolled down? Most people overlook this detail when giving their vehicle a quick wash. A few minutes with Windex and a clean rag is all it takes. Power windows not working? There's an easy repair.
