Windows.

[stagthelad]

It may sound a bit odd but has anyone had to clean the inside of a double glazed window, I have some marks on one of mine and it looks like we're water has evaporated and left the marks. The window has 2 bungs in it,one at the top on each side.
Any body think of a way to clean it please.

Is that house or caravan window?

Perhaps removing the small bungs would get rid of any condensation..if that's your problem.. careful they don't drop through between the two lanes...be ideal if it's done on a sunny day.....Gary

Two panes not lanes sorry

Is that a front window? There was a known fault on polyplastic front windows where the inside of the panes would rub together under pressure of towing , causing marks. A new window was the only solution

That was the problem on my 2020 Elddis. Fortunately still under warranty and replaced f.o.c.

New one still ok

We also had a problem with our front middle window on our Elddis Crusader Super Sirocco but it was replaced by the dealer because it was still under warranty

I had same problem on a new Coachman 545 2010, gap about 1 inch, replaced with newer type gap about 1 1/2 inch. Under warranty.
But back to the original post, yes we get smudges in the inside of the windows,
