Smear-free windows!

I've been cleaning windows for longer than I care to remember and, up until today, I could never get them smear-free. I'd think they were clean and then when the sun shone they were all smeary!

I've been researching this problem and this morning I cleaned my windows with a half water, half vinegar solution, applied with an e cloth and dried with an e cloth.

Well the sun has just come out and the results are pretty good - no smears! :-)
