I must have saved loads of money over the years by cleaning my own windows. I don't suppose it is such a big chore after all when I come to think about it. They don't get done until I cant see out of them, and that is only two or three times a year, so I don't know what I am moaning about.
I used to faff around with cheap spray cleaners made for windows, or water and proper window cloths, aren't you supposed to put vinegar in the bowl? All far too messy. Now I just cut up an old teashirt which is ready for the rag bag, and get my trusty Pledge from under the sink. I don't have a rag bag actually, I wear my clothes till I start looking like a tramp:-)
Anyway, this morning I cleaned the two upstairs front windows. Luckily they have the sort of openings that you can hang out of and reach the outside. My goodness, they were filthy. I don't think I have done the ledges for several years, I don't know what people thought as they walked by. They are now clean.
I know aerosols are not good for the planet, but this is the only one I have in my house, and as I use it sparingly and very rarely get it out, it lasts ages. Can't remember when I bought this one from the £1 shop, it's probably about three years old. Look at the muck on that cloth ;-O
