There are frequent discussions on here about the need or not to have a dehumidifier in the van. I know some people swear by a tray of salt.

My next door neighbour showed me a cautionary tale today. This week he has been busy replacing a faulty computer and telephone system in a building. This system is in a rack about 6ft high in a small room near the entrance. For some reason the caretaker decided to store sacks of salt in the room too.

Through evaporation, the salt has permanently damaged all the equipment, needing full replacement. Even the galvanised metal rack system is so badly corroded that that needs to be replaced too. - It was in the back of his van today.

Does anyone still think it a good idea to use salt to try and keep the inside of the van dry?

Ive been using salt for years and it does draw moisture from the air.Its left in a bowl in the sinks.Just a warning if your leaving salt in a bowl DONT leave it on the furniture as if it over spills the salt will cause damage.

I think there is a difference between some in a bowl and bags of it.Rice draws moisture too if left in a bowl.

Can't see the point in this practice ! you will be drawing moisture from surrounding air, unless a caravan is completely sealed, which is a bad idea.

Salt is essential in a caravan.

But if it isn`t used on chips it`s a waste of time.

I doubt that some table salt in a dish is going to corrode a caravan. I would imagine the caretaker was throwing bags of the stuff around causing salt dust to permeate the air.

When I had a small caravan I used to leave a bowl of salt at each end and some citronella air freshener blocks in the wardrobe and loo. I left all the cupboard doors open to allow air to circulate and raised the seat cushions on their sides, or took them out if it was to be stored for some time. The caravan always smelled clean and fresh when I went to it.

Anything used for dehumidification in a caravan is a waste of time and money. Any moisture removed from the air in the caravan will be replaced by moisture from the air coming in through the vents from outside. In effect you will be trying to dehumidify the surrounding area.
Much more important is adequate ventilation

If you have to, cat litter much more effective. Not sure about your mate's tale.

I agree, if there is excess moisture in the van then you need to open the window and let the moisture evaporate in to the atmosphere.

I was advised by the Tech team at the C&CC that it may be useful for the first day or two after using the van to remove any moisture in the soft furnishings from you living in the van. After that you just draw in moisture from outside through the vents etc, in other words, you are trying to "dehumidify your garden" or the storage area! Stopped using mine.
