I've cleaned them with :
liquid Spic and Span, OR Bon Ami,....gets all the scuffs off.
i've also soaked the hoses in a pail (or sink) of wrm water and detergent, sometimes liquid Lysol. A nicerinse and all of the dirt is gone.
magic erasers are great, as is Brasso, but, they are right: don't let that touch logos, script, etc.
Best of luck!
