keeping the exterior clean

[Ms Grumpy]

I think you will find different opinions depending on car color.

Wax: two or three times depending on how often washed.
clay bar: never used one
Washing: Only wash in the shade, dry with microfiber over and over, then I will pull into sunlight and dry again to make sure there is NO water left. Use Mequiar's car wash.
Detailing: For me having a black car I love the finishing spray called ICE. Not the brand by Turtle Wax, you can only find it in the Auto Paint stores.
Chrome: The ICE works really well on the chrome too.
Dash: The baby oil thing is great, just make sure you wipe if off well. Thanks flash !
