We've moved to a new house where the windows on the south side are big and unmissable from the inside! When the sun (or even strong light) shines through, EVERY IMPERFECTION on the glass shows up . . . and it looks BAD.
Now, I thought I knew how to deal with this situation. Firstly, a good rub using one bucket of lightly soapy warm water, then a jolly good rinse with another bucket of clean warm pure water straight from the tap, and then lots of vigorous rubbing and soaking up and polishing with a couple of big absolutely clean beach towels! Worked a treat on the big windows of our old north-facing house! But it doesn't work well enough in the new situation.
Strong sunshine today and you can still see areas of different degrees of cleanliness. (When the sun moves round and doesn't hit the windows directly, they look perfectly clean.)
So, any ideas on absolutely removing every resistant trace of grime, smears, filth, fly-dirt, and what-have-you from south-facing windows?
Thanks.
Eddy.
