Any cheap squeegee from wallmart will do. I like the 6 to 8" cheap ones but if you have to reach a lot, as wide as you can make it work. I hope that was near what you were asking. Never use a squeegee on eisen or flexible curtain windows Soft & clean chamois only.
Don't use a cheap squeegee with an aluminum frame. Anywhere the aluminum touches the glass will leave a scratch or deposit that is just about impossible to remove.
Ettore 8 in. Original Squeegee. All metal, no plastic. $6 at Home Depot or Amazon. Sizes from 6 to 18 inches. Rubber blade is replaceable, You can turn it over one time for a fresh edge. Two drops of dish detergent in a spray bottle and you are ready to go. I've had mine for 10+ years. They are stainless and made in USA.
