You mean like a paint brush? How about chems that dissolve debris and bugs and then pressure wash?
No, I meant like a wheel brush.
3M makes a spray on bug and tar remover that is commonly used to debadge vehicles but you have to be careful with any chemical that will dissolve anything that's stuck on your bike, it will also dissolve any wax you have on the paint so you may be creating more work for yourself than you would with a little elbow grease and a bristle brush.
