Bulkhead air vents - shall i block / seal them ?!

what's the purpose of these air vents - they are a pain in .. especially after using a solvent cleaner these dirty cloths stinks all day ... I thought to get a tube of silicone and seal them up?!

Just why not put stinky dirty cloths in a sealed plastic container then so no need to do anything else surely?

is more then that - carpet cleaning machine smells bad and I only clean it when i get home in the evening , lawn mower etc : ))

Open your cab windows maybe

worth making up a large tray for the machines to sit in. that way any foul stink run off will not be getting into your van body itself where it would be almost impossible to get rid of

you can wash out the tray each weekend with disinfectant .

another idea would be to remove a lot of the rubber draught excluder around the back doors , letting the stink out
