What in the world is chrome soap???  Only your chromes best friend after a hard days ride.  Chrome soap is a hard round bar of soap and comes with a soft round sponge.  Dampen the sponge and rub in on the chrom soap and watch is power off burmed on bugs and road grime off you exhaust, chrome primary and fork legs or anything chromed.  I personally use this on my exhaust that do not have heat shields, so the bugs get cooked on.  It never ceases to amaze me that it takes the trash off and makes the pipes look great!
