What you need is a very flat bladed scraper or flat knife, preferably a stiff bladed one ( one that doesn`t bend easily!) Take your scraper or knife have a look if the galzing beads are on the inside of your window or outside! If inside, you`re in luck this easier than it looks! you should see a joint right at the edge of the glass! place the scraper flat at the joint and hammer in! now with a little force sideways away from the wall the bead should start to come away! If beads are on the outside, you are probably better off getting a professional to take a look as this is sometimes a lot trickier! hope this helps!
