Thanks for replies. As for using virosol or tfr, does it take long to wash any splashes off windows?
No Steve, just give them a scrub and rinse them down, jobs a good 'en.
On new cleans if frames are a bit dirty I'll use Virosol to clean them up first time round, gets them all shiny, frames and glass. So, Virosol on my brush, neat, then scrub on frame and glass, do tips and bottom one side. Go back to start, scrub with water on, rinse off. Next. After I've done all house, go round with my normal glass brush, quick clean off glass and rinse. Virosol is great stuff.
Others on here may do it with other cleaners, tfr etc.
