    Hi

    just noticed today that the bathroom mirrors are full of condensation.
    not seen this before - even throughout the snow and following thaw.

    Van is in storage and I've left the bathroom door closed up until now and seeing this, I've opened it.
    Only difference to the van is I've added two air-freshners (the car tree type on elastic) to the lounge area, so don't think that they're the cause.

    any ideas why I've got condensation now and have never had it before?

    Thanks Sid40, I've kept the door open and will try vent where possible and will keep an eye on it

    Cold glass....warm air....condensation.

    Same thing as condensation on your windscreen....colder air on the outside cooling the glass, warm moist air inside from breathing, cooking etc

    Leave the door open and you shouldnt hsve a problem.

    Enter stage left....the dehumidifier fanatics.

    I know I am picking up an old thread but I am having big condensation problems.
    Like @pappajohn and Sid40 I believe the remedy is venting. But, I have made sure both floor vents are clear and I have cranked open the smaller roof vent. The cupboards are empty and the doors open including the washroom door.
    The van is parked in our drive and has a cover on the outside of windscreen?
    Today, as previous days, all surfaces running with condensation including taps, mirrors doors etc.
    I don't want to go down the route of heating or dehumidifying but thinking that is the only way.
    Had an Autosleeper before this one and didn't have any problems.

    I used a Unibond Aero 360 moisture absorber last year, I was pleased with the result. Available from Wilko or DIY shops.
    Worth a try as not expensive and refills available.

    Have to say that is unusual to that degree when the van is not been used, is the toilet cassette empty, no wet dish clothes around, a couple of windows on the sneck? No slight leaks from a skylight, have a good feel around.

    Morning RbA I share the same opinion as Caroline I would expect there to have to be a lot of moisture somewhere for that much condensation to form

    Do you have the heating turned on? It has turned colder this week, but TBH we have our heating on a low setting all the time and don't get condensation other than the usual windscreen when away in it and very cold outside

    ventilation should really be the key I would say, bathroom vent opened a bit more maybe, plus another to help air flow (y) but it does sound like something more serious might be causing it o_O

    I have this problem in my garage at home, the cement board roof runs with condensation and drips onto my car. It only ever happens when there is a big change in outside temp, warm to cold. I cut large vents into the door which seems to have helped.
    The inside of your Moho could be the same, more ventilation to cool the inside down at the same rate as the outside would be my guess. (y)

    I feel for you as none of us would want to have so much moisture in the motorhome.

    I’ve used these for past 6 years and have never suffered regardless of what the weather is doing. Readily available in the shops. Saw them in Tesco today as well. In my opinion the scented refills aren’t cheap, but go for the standard blue and they’re worth it.

    Also leave all my doors ajar to circulate the air inside.

    Good luck and keep us posted:)

    I don't have any problems with our van but the car in damp weather the screen gets covered in condensation, easy to remedy set the heating controls to recirculating it's reduces the amout of damp air coming in. Well worth trying.

    I have 2 of these behind the seat in my car and don't really suffer that much from moisture.

    As it's a convertible with a very light coloured roof lining, I'm always on the lookout for any signs of damp or black spots on the fabric.

    So far so good and it never ceases to surprise me just how much water I tip away from them each week:)

    Hmm, not to worry you but I recently discovered the main skylight had a leak. Fortunately I caught it quickly and had it seen to but it was still quite wet around the enclosure. The chap who fixed it said it may take a little while to dry out.
    Since then, despite properly ventilating the van I've noticed condensation on the windows, which normally are fitted with internal insulated covers. I believe it is the damp slowly drying out.

    I've noticed ours is getting steamed up mirrors in the bathroom and we have an extra vent in the roof as well as leaving the sky light open slightly can't find any moisture anywhere all I can put it down to is that the traps on the shower and basin have water in them and we have two in the shower.
    My solution was to open door and put fan heater on for a few hours which seems to have done the trick.(y)

    Thanks everyone. Today there was no condensation so I am wondering if is was a sudden change in th weather. Over a couple of days but I wasn't able to check yesterday. There is nothing left damp in the van and when I drained the system I even blew down the taps. They are left half open but they don't have u bends. Both under neath drain taps fully open.
    I have had a look / feel around for leaks but thankfully no sign.

    No heating on and plenty of ventilation.

    I do have a large mains dehumidifier for the house as we get mould since having walls filled ( big mistake many years ago) . But not convenient to run mains cable out.

    Will try the small ones suggested but at present a bit incapacitated due to minor op yesterday.:(

    Fingers crossed then, on another note, one of the worst things to do to an house is put cavity wall insulation in, especially if in an exposed area, but that's for another forum.
