Ive decided to give the 'air con bomb' a go, as ive noticed a slight nasty smell in my car. Can anyone recommend any specific brands? From some quick googling it seems to be a simple enough procedure, with instructions and the best location to place the bomb varying greatly. I've read its best to remove your pollon/cabin filter first? If anyone could share any advice before I do this for the first time, that would be super appreciated! I would quite like one with some type of anti bacterial element too it rather than a glorified air freshener if that makes sense. Thanks.
