A proper disinfecting would go a way to getting rid of bacteria hard to say about chemical smells however they may not be removable depending.

Remember every nook and cranny should be rinsed washed with soap and water scrubbed rinsed and then disinfectant needs to saturate the area and the correct contact time observed and in some cases rinsed away after. It is a huge amount of work it may require disassembly depending on if there are multiple parts.
