Caustic soda or industrial oven cleaner will clean them out.
As for the dents depends how deep they are. If shallow then fill with brazing or leading, reshape and paint.
If deep you can weld something on to get a grip to pull out with something like a slide hammer then braze/lead. Only other option is to find some one who does pipe hydro forming when they pressurise with water then heat the area to soften the metal and the pressure will push it out.

With our RC /18 cars when we get a ding in the tuned pipe we cork one end, fill completely with water, seal the other end and put in the freezer. Once frozen the water expands and pushes out the dent. You will need a VERY big freezer though!  Sorry.....I'm gone! Mike |

Typical Exp chamber restore on Moto X bikes is that the bespoke :-) shop pressurizes the chamber to 10/11psi with Air then heats the dented area carefully. Soon the air pushes out the dents. Google for this and you should find piccies of completely flattened (ruined?) pipes looking good as new after repairs. Dunno if it's a DIY adventure though
