Condensation Cures

Never had the problem

In storage I would be worried if I had wet surfaces or moisture on the inside of windows, I have suffered once in four winters with mold spots on the curtain linings but not on the curtains themselves and put that down to a very wet and mild winter. I use nothing and so far this winter all is good (fingers crossed)

On a nice dry sunny day I visit the storage every month (only 1 mile away) to check everything and air the van out, but nothing more.

As with EasyT,  never had a problem.  It’s stored away from heating so the temperature of van is the same as the outside. 

In the "old days"LVs did, it seems,suffer from condensation more than now, as maybe now its the better insulation, our last three c/vans and also our two  previos m/vans have not suffered, and we have not done anything,

But then we have in the last few years used them far more so maybe it needs a prolonged lay up for condensation  to be a problem? 

And all our LVs have been kept when not in use, in open storage compound

Not had any problems, keep the van well aired, cupboards etc open, check it frequently. Big changes in temperature might cause an occasional problem if left unchecked. We know the cold spot in our van, a cupboard in the rear so keep that open with a good air flow.

Just the same as Brue, keeping the van well aired is the main way to prevent damp. I once tried using the small crystal type dehumidifiers but was not impressed and anyway if the van is well aired you would be drawing the damp air inside.

I also have a small 500w heater set to frost-stat just to keep a constant temp.

Lucky to have van on drive.On any nice sunny winters day we open all doors and allow fresh air to circulate. Never a problem.

If you have 'condensation' problems in a stored caravan, then  I would guess you have some source of damp in that van.  Our caravan is now eighteen years old and has no problems whatever despite being in storage for the last umpteen years - orignally on a wet and windy Yorkshire hill, and now elsewhere. 

When spring comes around check the caravan with a damp meter, make sure there are no wet corners due to leaking seals, faulty sealant, window rubbers, etc.,   I would guess that you will find somewhere that is damper than it should be.  Solve this problem and you'll solve the problem of 'condensation'.

ValDa is right, if you have water ingress which is 'pooling' somewhere in the van this can only make matters worse. The secret is to keep the van as water tight as possible and the construction 'fabrics' as dry as possible. Keep exterior air vents clear and then ensure good air circulation throughout keeping all doors and lockers open thus reducing any dead air pockets. Finally, remove as much of the material from the van which could absorb water and store it. As for moisture absorbing crystals doing any better than this the jury is out as the best you can ever hope for is to maintain the same degree of humidity as that existing in the prevailing atmospheric conditions. Whatever the crystals take out will be balanced out by that in the air mass.

We always do our best to put the van away in a dry state. So If we were on a service pitch would not use the onboard shower on the last morning and steam up the bathroom. Defrost and dry out the fridge the night before leaving. Anything remaining is fine in a cold bag in the car overnight. Remove all bedding to the house during winter.

We are lucky in that our storage site is fairly open, with good air movement. No trees or grass just bare well drained gravel.

When we were new to caravanning we were talked into using the crystals. However, they just kept attracting moisture. When you think about it  you are never going to dry out the atmosphere, as if the van is ventilated, you are trying to dehumidify the world.😂 Well in our case, Nottinghamshire at any rate.

So far we have had no problems.
