[dinny]

they are filthy and I have an unprecedented spare hour....

Thanks!

ended up doing the following and am rather pleased with them, esp as it's been sooooo sunny - the litmus etst of windows

1. fill spray bottle with water and vinegar
2. spray liberally and clean twice with J cloth
3. spray again, finely, and clean straight off with kitchen roll

voila!
