    image.jpg No it's not a Tina Turner thread, or smutty in any way, this is serious :whew:

    Anyway, we've been parked up for a week in the sun and our rear windows are steamed up (between the double glazing).

    They are not really sealed units as they have loose fitting plastic bungs in the top corners. I thought that they would clear after a few warm days, but they haven't.

    Has anyone had this issue before (and found a cure?)

    I'm concerned that they will eventually stain and never look clean.

    Normally clear after a day or two with the bungs out, surprised you said lose fitting bungs they are normally very tight and often have to fit new ones after removing.
    Try leaving them out during the day with some heat in the van and replacing them when the sun goes down, should clear after a few days.
    It happens as acrylic is microscopic and allows water/vapor to enter thought the acrylic panes.

    You can sometimes speed up the clearing of the condensation by removing the 2x bungalow and use a hair dryer to blow warm air through 1x of the bung holes once all clear refit bungs. If they are a bit loose use a small pad of cling film by folding a few times and put this over the hole and push the bung back in the hole, this takes out the slack. Make sure you don't try making the pad too thick as it could work like a paper punch and shear off the cling film which could then drop in between the glazing.

    One of our windows 'steams up' mainly because the two layers have separated along the bottom run, unfortunately only a new window will fix it!

    Can't the two parts be resealed/ bonded. If sufficient gap could be achieved to get some adesive in, capillary action could do the rest till it hardened/ cured. There's a creeping crack cure that may be useful if you can get it in. If it's gone on the bottom rail, it may be possible to separate the whole unit then resealed/adhere.

    We did try to reseal it with two different products, both were correct for the job but neither worked for any length of time.
    Apparently there is a company in Leeds that will repair them but only if they haven't been 'messed' with first.
    So we will have to invest in a new window! One day.

    Try, O-Leary Motorhomes, Plaxton Bridge (North of HULL) He gets windows for ALL the major manufacturers, and being "Surplus" are often well below retail. You just might strike lucky?


    Ref: the O/P:-
    Also. I do know that Some Glass double glazing manufacturers used to put a few grains of warm DRY silica gel into the cavity before extracting the Air and sealing??.

    I have had this problem on one window. I removed the bungs and on a sunny day as they started to steam further, I used an 12v airbed pump on suck. This cleared the window fine. You could see the mist clearing to the nozzle. I know the cause of my problem, it is fine cracks appearing in the 24 year old windows.

    I had tried the hairdryer trick before but this only caused the window plastic to melt and deform.

    Re the hairdryer trick, we have a small funnel in the kitchen, (at home) that, on the end of which, is a short length of flexible plastic tubing.
    The tubing is narrow enough to go through the 'bung' hole.
    That would allow you to use the hairdryer without it getting too close to the window.

    Don't forget to replace the bungs after they clear. Mine was left without bungs after little hands pulled them out. Only noticed after half a dozen files crawled in and died. Believe me you will won't complain about the mist any more :LOL:

    Thanks for the ideas everyone, I'll remove the bugs if it's sunny tomorrow, and try the Hoover/drier trick when I return to Blighty.

    Dry air from a compressor with a water filer on would pass enough dry air to clear it with two holes one in and one out. just do not put pressure in it or you will blow them apart

    I preferred bungalows with microscopic windows - confusing but the mist is clearing(y):D.
