How to Clean Bay Windows

Bay windows are more ornate versions of their flat counterparts. Because there are considerably more windows to clean in each unit, bay windows require a bit more care. Follow this quick, 3-step method for perfect results.

1. Clean Bay Windows with the Right Squeegee

To clean bay windows, it helps to have a squeegee that fits the panes. You can use a hacksaw to cut a squeegee down to size. First, trim the metal channel one-quarter inch narrower than the window panes of your bay windows. Next, file the cut edges smooth to avoid damaging the panes. Use a utility knife to cut the rubber blade to the pane's full width. Fit the rubber blade into the channel so that an extra eight of an inch at both ends.

2. Clean Bay Windows by Scrubbing the Panes

Always use a handheld sponge or soft brush on multi-pane bay windows. Many professional cleaners prefer a natural sponge because they are firmer and more absorbent than the synthetic equivalents. Make the cleaning solution using a tiny bit of liquid soap in water. Then rub each pane of your bay windows from side to side and top to bottom. Work the sponge edges or brush bristles firmly into the corners to loosen stubborn dirt build-up.

3. Wipe Bay Windows Dry and Streak-Free

Pull the squeegee down each bay windows pane in a single stroke from top to bottom. To prevent streaking, clean the blade with a rag after each stroke. Add a little bit more soap to the water for the next cleaning session if the squeegee squeaks a lot. Remove any remaining streaks on the glass with a clean, dry cloth. Finish by drying the muntins and sill with a rag.
