Condensation in double glazing

the small window adjacent to the kitchen in our Swift Conquueror 480 has gained some condensation between the inner and outer "panes". Any hints, please on how to extract the moisture.  I notice two small plugs near the top of the inner "pane"- Does one remove them and blow dry air through the cavity?

    Yes Jemmydog, often just leaving the window in direct hot sunlight for a few hours with the plugs removed will do the trick, or I heard of using a fish tank type air pump to 'flush out' the damp air, which might be necessary if the condensation is heavy.

    If the window has only just recently had sunlight on it I would tend to leave it to dry naturally, this is a fairly common problem as the weather warms but usually occurs earlier in Spring.

    There was a detailed discussion on this subject, in this section at the beginning of April. If you go back about 8 pages you will find it. It is headed "water in front window"

    I tried to find the thread using the search facility but that didn't work cry  When eventually I found it (retracing two pages at a time, Aaah), I tried to post a link, but couldn't work out how that is done. I highlighted and copied but then couldn't paste. It's probably simple when you know how to do it.

     Thanks Freelander, hopefully the OP will see it and find it informative.

    Useful feedback-thanks to the four participants. The idea of a small air pump sounds spot on. Unfortunately the nearest I can get at present is a Miele vacuum in blow mode with an inverted funnel over the end to "downsize" the tube! ......on second thoughts that Heath Robinson contraption may blow the panes apart so an electric pump used to inflate an air bed probably more sensible.  Thanks again!,

    Hi Jemmydog, you don't say how old your caravan is. My experience is that after approximately 5 years, the panes do tend to start misting. I have had success with a hair drier gently warming the pane (plugs out) at the bottom working up towards the top. I have also had a vacuum in normal mode placed close to one of the holes. Worked well for me. If your caravan is younger, you possibly have a damp problem in the van. My current van windows had problems after 12 months and once the damp problems were rectified, we have not suffered.

    A hair dryer will also soften the bungs so you may be able to get them out without them breaking.

    DaveT- 8 years old. No damp at present. Your solution using normal vacuum mode plus the additional comments re warming the plugs appear the most straightforward way forward.  On another topic - appreciate your comments on "last chance" posting.
