How do I clean out the air con in a citroen xsara picasso?

You can get a spray can which you put inside on the floor behind the front seats. It pulls the spray into the aircon system. Put your aircon on and follow the instructions on the can. Got mine from tesco but Halfords sell it as well. It kills all bacteria and smells are gone. I thought it worked well. Hope this helps
