WD-40 and wipe off the excess.

Works every time.

 

Wd-40

 

Used WD-40 on a Street Bob I had,worked great.

 

+1 It works great and you don't have to buy any new crap.

 

I use ice wax by turtlewax on everything works grate even on flatblack paint and it also removes wax buildup from pastwax.One bottle has lasted me over 4 years.

 

I would go buy a new 2011 screaming eagle street glide.

 

As many others saud: WD 40 & Toothbrush,doing it when the motor's a little warm works well but not necessary.

 

Like an earlier poster said, Pig Spit. I've been using it for over fifteen years. Absolutely no scrubbing, just spray it on black wrinkle paint then wipe off. Try it.

 

+1, and it keeps engine cases looking like new!

 

I used Pig Spit for the same problem and I was very pleased and easy. Sprayed cylinder fins and everything looked new. Spray and drink beverage of choice no scrubbing.

I use pledge on other areas but maybe I will try it on cases. I am not a big fan of WD40 on any paint but I know some other that use just not me.
