End of season, so what do you use to clean the underside of your car (door car)? I have a good pressure washer and have experimented with different degreasers and detergents. I am just wondering if one type is better than another.

The product Awesome has been highly touted on the site in the past. You can only find it in discount stores. I've been using it for at least a couple of years and bought another gallon just last night. I've recommended it to my daughter, and others.

Microfiber towels with Windex followed by Lucas Slick Mist

A Good quality Citrus or green cleaner to get any grime off then SHOCK IT spray nano polymer polish. I buy it by the gallon much cheaper than 8, 10 or 12 bucks a bottle at the stores. Lasts and protects. I have used Meguirs, Lucas, Mothers, Chemical Guys and they are all good to ok but the Shock It is the best detail spray I have used hands down. If you can Wax it after I say Meguirs synthetic is tough to beat.

Either Meguiars super degreaser, or zep degreaser first. Then follow it up with car pro tarx to get any rubber off. DON'T LET the tarx get on your slicks though if you use it.

Great point on slicks.

My shirt seems to take a nice amount of oily dirt from the underside anytime I get under the car.

After 25 years of racing and two engine explosions, it’s pretty nasty but shouldn’t rust.

Simple green in the concentrated formula is hard to beat.

I use Greased Lightning and a garden hose before I put my Nova away for the winter.
