Had a new d glaze window put in a couple of weeks ago. All is fine except I notice some red brick dust from drilling the walls had been left on the lower steel runner. Tried to wipe it off before any of it found it's way underneath but of course some did. Is there a way to get this stuff out as when I open/close the window I can feel it graunching away... I thought to try 1) flush of the thin film of (probably) oil off the runner using eg fairy liquid. 2) wash with water 3) Dry it as much as possible then try and vacuum it the struff out. If I could get the runner completely off then I could give it a good clean - but am bit reluctant to do that on a new window. I could of course call the installers to come and "fix" it... rather not though
ps the effect is like when get brick dust in a light switch. From then on, it's had it, grunch grunch. (That was before I used plastic bags and masking tape :-) )
