Introduction
Wood windows with a a href="https://diyuniversity.com/catalog/info/id:255,cms_featured_course:1">natural finish on the inside look great when they're new, but moisture, temperature swings and harsh sunlight eventually make the varnish fade and flake away, especially along the bottom of the window sash and on the sill.
It looks like an intimidating job, but usually the only part of the window that needs work is along the bottom — the rest of the sash and trim can just be lightly sanded and recoated.
Follow the steps ahead to get the job done.

Project step-by-step (4)
Match the Old Stain
Carefully remove the wood cover of the casement operator (or other piece of trim) and use it to match the stain. The easiest way to do this is to take a piece of the trim to a paint store to match it.
Scrape Off Loose Finish
Use a sharp scraper to remove the old finish. Pull the scraper smoothly and carefully to avoid gouging the wood.
Sand Worn Finish
Sand side pieces heavily in worn-out areas and lightly elsewhere. Stop at edges or corners next to undamaged wood. Use 120- or 150-grit sandpaper.
In partially damaged areas, feather the sanding into the undamaged areas, then lightly sand the rest of the piece to prepare it for a new finish.
You don’t need to sand and recoat the entire window if only a few pieces need it — just stop at an edge or corner.
Apply Stain and Finish
Rub stain into the sanded sections of the window. Wipe off quickly, then apply more as needed to darken the color. If the gloss doesn’t match the older varnish, buff it lightly with extra-fine steel wool or pad to dull it.
