Best is often a matter of opinion.
- Simple Great
Great for Rocker Panels and Wheel Wells.
Bumpers, tires, and wheels as well.
Make sure to be very careful with Simple Green.
It has a lot of color additive and flash chemical.
It can stain paint and clear coat quickly.
Make sure to be immediately on top of your work with a hose or a steamer, and wet rag to follow.
It does a great job, but you need to dilute it and be right on top of what you are doing.
- Meguiars APC.
This product is fantastic.
I have been using it heavily over the last couple weeks.
Testing on work trucks as part of paint decontamination, as well as the typical cleaning of wheel wells, tires and wheels, etc.
This product really impresses me.
