Introduction
Renew the lustrous appearance of stained and varnished woodwork without the messy stripping process. We show you how.
You can dramatically improve the appearance of stained baseboards and varnished woodwork without all the work and mess of a complete stripping and refinishing job. We’ll show you a much easier process here—and you may even be able to eliminate some steps if your farmhouse baseboard trim is in better shape than ours. Just gather the supplies in a 5-gallon bucket and tackle the renewal project one window or door at a time whenever you have a few spare hours. Start in a corner or in an inconspicuous area—better to learn from your mistakes there than on the front door.

Project step-by-step (9)
Step 1
Remove old paint spots
The first step in renewing your woodwork and stained baseboards is cleaning them to remove grease and grime and create a contaminant-free surface for the new finish. Wash the woodwork with a TSP substitute. Use just enough cleaner to wet the surface. Scrub with a sponge dipped in the cleaning solution. Then rinse with a sponge and clear water and wipe off the wood with a dry rag.
If there’s paint slopped onto the edges of your farmhouse baseboard trim or spattered on the surface, now’s the time to clean it off. A rag dampened with denatured alcohol will remove most paint spatters. Alcohol won’t harm most finishes, but it will dissolve shellac. Don’t worry if some of the finish comes off. You can touch it up later. Protect the walls with masking tape to prevent the alcohol from damaging the paint. For tougher paint spatters, use a fine synthetic abrasive pad (such as a 3M Wood Finishing Pad) dipped in denatured alcohol.
Step 2
Scrape eroded areas
Scrape away the badly weathered finish. A carbide paint scraper removes the old finish much faster than sandpaper, but be careful not to gouge the farmhouse baseboard trim.
Step 3
Bleach out dark stains
Bleach away deep stains that scraping or sanding won’t remove. You don’t have to scrub; just let the oxalic acid penetrate and lighten the stain.
Mix the oxalic acid in a plastic container. Add 1 oz. of oxalic acid powder (about 2 tablespoons) to 1 cup of hot water and stir it until the powder dissolves. Then, brush the solution onto the stain with a disposable sponge brush and let it work for 20 minutes.
You can repeat the process to further lighten the stain. Wipe the bleached wood with a sponge and clear water. Then, neutralize the oxalic acid by applying a solution of 3 tablespoons of borax to 1 gallon of water with a sponge. Finally, rinse the bleached wood with water again and let it dry overnight.
Caution: Wear protective gear, including goggles, rubber gloves and a long-sleeve shirt, when you work with oxalic acid.
Step 4
Sand bleached areas
Sand the bleached wood after it dries. Start with 120-grit sandpaper. Then sand with 180-grit. Vacuum the dust before staining and finishing.
Step 5
Roughen the old finish
To make new finishes stick well, slightly roughen the old finish first. Synthetic finishing pads are the best choice because they conform to profiles and aren’t as aggressive as sandpaper. Buy medium and fine and experiment in an inconspicuous area. Use the pad that roughens the finish without removing any stain on the farmhouse baseboard trim. Vacuum the dust from the surface before wiping on a new coat of finish.
Step 6
Fill holes
Fill holes left by nails or screws with soft wood putty. Wood putty is available in many colors that you can blend for a perfect match. Application is easy. You just push it into the hole and wipe it off. There’s no sanding required.
Buy several shades of putty, ranging from dark to light, that are similar to the color of your trim. Then, mix them to match the wood surrounding the hole. Push the putty into the hole and wipe off the excess with your fingertip. Then, remove residue from around the hole by wiping over it with a clean rag. If your woodwork has filled nail holes that have darkened and no longer match, pick the old filler out and replace it with soft putty. Buy water-based putty if you plan to use water-based polyurethane.
Step 7
Apply matching stain
Completely refinishing the area may be the only way to make flawless repairs to badly damaged doors, windows and moldings. However, you can greatly improve the overall appearance of worn or damaged wood with less drastic measures.
Disguise large areas where the stain is worn away by dabbing stain over the light areas to blend them in. The patched area may not match exactly, but at least the spot will be less obvious. Or simply wipe the surface of the wood with a rag dipped in stain to fill in small scratches and imperfections—you’ll see a big improvement. Wipe the stain on. Then, wipe off the excess with a clean rag. Allow the stain to dry overnight before you apply the finish.
One of the trickiest parts of a wood restoration project is finding stain to match. You can pry off a small piece of trim and ask the paint department to mix stain to match. Some paint stores and home centers offer inexpensive sample packets of stain. You can choose several samples that are close to the color of your wood and experiment in a hidden area to find the best color match. Then buy a larger container.
Another approach is to buy two or three cans of stain close to your woodwork’s color and mix them to get the right color. Use an eyedropper and disposable plastic cups to mix small batches until you get the proportions right. Keep notes so you can reproduce the results in a larger batch.
Step 8
Wipe on polyurethane
The final step in your trim renewal project is to apply a fresh coat of finish. Wipe-on polyurethane is a good choice because it’s fast and easy to apply. You simply wipe it on with a soft rag and let it dry. Each coat is very thin and dries quickly. You can recoat in two or three hours for a thicker finish for extra protection. Several coats of wipe-on polyurethane are required to equal the thickness of one coat of brushed-on varnish, but it’s easier to get a smooth, drip-free finish with wipe-on poly.
Fold a cotton rag to create a pad. Then, dip an edge of the pad into a container of wipe-on polyurethane and press it against the side to wring out the excess. Wipe the polyurethane onto the wood in long strokes in the direction of the wood grain as you would if you were using a brush.
For window stools or other trim exposed to sunlight, consider using spar varnish. Spar varnish has built-in ultraviolet protection and is more flexible, so it holds up better in areas exposed to sunlight and water. Experiment on a scrap of trim or in an inconspicuous area to see if the slightly amber tint darkens the color too much.
When you’ve completed all of the steps above, your woodwork will look like new and be protected by a fresh layer of finish. If you don’t have time to do an entire room from beginning to end, just tackle one door or window whenever you have a few spare hours. You’ll be done with a room before you know it.
Step 9
Faux wood patch
Dings and dents too large to fill with soft putty present a unique challenge. If you can’t replace the farmhouse baseboard trim, the next best thing is to patch the damage with filler and color the patch to match. Use hardening-type filler like Durham’s Rock Hard Water Putty.
Apply the filler carefully with as little excess as possible to minimize sanding. Let the filler dry and sand it smooth, being careful to avoid sanding away the finish on the surrounding wood. Then, use felt tip markers to “paint” the patch to match. Art supply stores are the best source of markers—you’ll find endless shades of brown. Most other stores carry only one or two. The repair won’t be perfect, but you may be surprised by how inconspicuous it is from a distance.
