Aluminum crank out windows

I am remodeling our kitchen and we have older aluminum crank outs that have a tendency to have mildew build up on them every now and then. I know the best thing to do is probably replace them but finances only allow one thing at a time. My question- I took all the old paint off of them around the edges and steel wooled them clean like new. I recaulked around the outside where the wood meets the metal with a silicone caulk. Is there anything that I can apply to the aluminum to retard the mildew from forming on them? I realize that any situation where moisture comes in only adds to the problem but along with Alykd (?) paint on the wood I thought there might be something to cover the aluminum with. Thanks in advance!!!! This is a great website!-----Vince

Vince, as long as that old aluminum frame casement window is in your wall I think you will have the mildew problem, no matter what you do to it. It is caused by heat and cold transfer thru the frame and single pane glass, and the seals in the window are probably shot as well. You should be able to get an inexpensive dual pane vinyl window at Home Depot, Lowes, etc., for less than $200. (Since this is the kitchen, I'm guessing it's probably a 3-0 X 3-0 or there abouts) Even an inexpensive vinyl window will be better than what you have now.
