Usually the metal rib weatherstripping and the lower sash are removed like this:

1. Unfasten the metal rib strip at one side of the sash. It may be held onto the jamb with brads or screws. Usually the strip is fastened to the jamb with just two or three screws or brads, one at the top of the strip that sticks up above the sash when the sash is down, one at the bottom of the strip when the sash is up, and possibly one in the middle of the strip. If there are many brads, then it becomes less likely (although still possible) that the strip can be reused.

One method to unfasten the brads or screws that are stuck is to use a Fein sander with the .8mm metal cutting blade. Slip the blade between the jamb and the weatherstrip to cut through the nails, bzzzip, bzzzip, bzzzip, the nail heads pop off and the weatherstrip comes off with no stress, bending or tearing. Works on the sill strip too.

If the flange right next to the brad holes is bent up during removal it can often be flattened out for reuse by tapping lightly with a hammer on a flat piece of steel. If the rib gets kinked, the strip is usually not reusable.

2. Loosen and slide up the strip. Sometimes the metal of the flange has been formed into spurs that stick into the jamb a bit. Also, there may be a piece of roofing felt between the strip and the jamb that has stuck the strip to the jamb. Slip a thin putty knife between the strip and the felt or the jamb and work the putty knife up and down along under the strip. The lower end of the strip usually "saddles" over the rib of the strip on the sill, so slide the strip up off the rib and then slide it a little further up so the bottom end of the strip will clear the stool when the sash and strip are swung out.

3. Pull the cord or chain straight out from the jamb. Put a temporary hold on the cords or chains with a spring clamp up by the pulleys. This helps gain some slack in the cord or chain to make the next steps easier.

4. Swing the edge of the sash and the strip together out away from the jamb.

5. Remove the strip from the edge of the sash. The rib of the strip should come right out of the groove in the edge of the sash. Sometimes there is a piece of roofing felt or building paper underneath the strip--save it for reuse, or plan to get some more for when the sash is re-installed.

6. Set the sash on the stool. Remove the ends of the cords or chains from the edges of the sash.

Great idea to nip the heads of the brads off! I just started a window project to help out a friend with 24 gorgeous historic windows on their 1918 Craftsman home and wasn't sure if the weatherstripping it has could be removed and reused. Can you post about the upper sash?

OK, for the upper sash you have to remove the parting beads. Then go after the weatherstripping the same as with the lower sash. Sometimes it's easier to loosen both the left and right weatherstrips. Then slide the upper sash down about 8" to expose the pulleys so you can see them. Then swing the sash out.
