I live on dirt road that gets chloride put on it a couple times a year. I want to make sure that I keep the frame and all of the under side clean but the dirt from road seems greasy or oily. Quick wash isn't cutting it. Harley has a ton of product out there but I am wondering if anyone has any suggestions that might be less expensive.
thanks

 

409 and paper towels to get the worst part off. Then more 409 and rags. Works for me

 

I like Simple Green.

 

Dish liquid and water.

 

Some ships use Tide to clean the bilge, I have used it to clean driveway spills.

Works fairly well and the wife never misses a small amount.
