I'm a big fan of:
Maxi Suds II - this is my standard wash
Citrus Wash - when I want to strip the car to get ready for polishing
Silk Shine - this is a great product on tires and plastic (nice matte finish)
No More Bugs & Tar - great for removing caked on bugs
Honeydew Snow Foam - just started using it, it seems more foamy than Maxi Suds II, and I might just turn this into my standard wash.
