Use the shampoo from the bathroom to wash the car.
Don't know why you're convinced walmart sponges are made with rocks, but ok. Steal the one from the kitchen sink. Use the washcloth from the bathtub when you take the shampoo. Either way, the car is clean. Even underpants work well.
If you're really paranoid about rocks in the water bucket (mixing bowl snatched from the kitchen), use a broken florecent light grate on the bottom. These are found in office dumpsters everywhere. For free, put a hairbrush in the bowl, bristle side up. Rinse it after use btw.
For nearly free clay, use cheap modeling clay. Playdo may work, but I've never tried it myself. That's $1 for a whole tub. Free if you've got access to someone with a small kid.
for free polish and paint reconditioning, change your oil. Otherwise, keep wiping the dipstick. Smear it all over the paint. Then wipe it off. It looks really nice for a few weeks. That's why the greasy paw prints from a mechanic look so good.
For the wax job, the furniture polish/wax works. Not long lasting, tends to atract dust, but it works. Floor polish/wax/sealant works even better. Lasts longer, attracts less dust. The stuff can be found living under the kitchen sink in most houses. Especially if a woman lives in the house.
If you're willing to spend money on waxes, the Mequires Deep Crystal stuff is cheap and pretty durn good. Looks nice, doesn't last forever. Cheaper still, whatever you find moldering away on the basement shelf. Really, any of them will work, at least for a few weeks.
