Scraping hardened concrete from a mixer
 
is there an elegant (chemical) solution or do i have to keep digging and chiseling ?

Use a fast rotary tool with proper disc attachment to remove it.

Rotozip will do... the best attachment I find working for me so far are those thick(1/4") sanding disk... but in theory... anything will work... just of different speed and some attachement allow you to reach some area whereas other couldn't.... try to use what you have on hand first before spending $$ on new ones...

A regular concrete mixer? hit the side with Sledge hammer. Or dynomite will work also

I think the poster is talking about those left over mud which cannot be knock off easily though....

who cares then. Ever seen a concrete mixer clean as the day it was bought?

post a picture of the tool you are talking about? I can't see any rotozip attachment that would cut through concrete in a timely manner I agree with the sledgeomatic routine. For godsakes it's a concrete mixer not a dinner plate. Mine is pretty clean although I wash it after using it.
