I left my walking boots in my car, went somewhere to walk Rox and I got them out and realised they smelt really musty and mouldy (my car gets damp so anything I leave in there stinks!). I then made the mistake of taking the boots in the house but leaving them dirty in a plastic bag, thinking I'll clean them later but a few days on I eventually got them out of the bag and the smell was worse than before and they actually had mould growing on them! I probably did the wrong thing, I wasn't sure how to clean them so I wiped them with antibac wipes! They still stink! They're sort of like material with mesh type bits on, Karrimors exactly like these Karrimor | Karrimor Mountain Mid Top Ladies Walking Boots | Ladies Walking Boots How should I go about cleaning them to get rid of the smell?
