Step 1 - Identify the Finish

You will need to know what fam­ily of finish your piece is before it can be revived, and that takes only a simple solvent test. Because you’ll be play­ing around with some chemicals, have your eye wash bottle close at hand, wear clothing and shoes you don’t mind get­ting solvent on, then don your safety eye glasses (preferably chemical splash goggles) and neoprene gloves. Locate an area to work in that is well venti­lated and well lit, then place a plastic drop cloth down and turn the piece over there onto its back. Select a small, 2″ square area that’s as inconspicuous as possible and clean that area with a rag lightly soaked in turpentine. Now that it’s clean, take a good look at the test area. If you can see open pores of wood under the finish and the finish is not glossy, odds are that an oil and wax fin­ish has been applied. If that’s not the case, test for shellac. Take a fresh rag, soak it in denatured alcohol and wring out the excess before rubbing the test area gently. If the finish starts to dissolve right away or becomes sticky and dark­ens the rag, the finish is indeed shellac. If that doesn’t do anything to the finish, clean the test area again with turpentine and, once dry, start your test for lacquer. Do the same as before, only this time use lacquer thinner. If the finish comes off, it was likely lacquer. If nothing so far has affected the finish, it’s most likely a modern, vanish-based finish. Congratulations, you’ve identified the family of finish you’re dealing with, and are ready to begin the revival process.

Step 2 – Initial Cleaning

Working in that same well lit and ven­tilated area, get the piece ready for its initial cleaning. Remove any manufac­turer’s labels and hardware. If it’s not obvious where these came from, label them clearly so they can go back where they came from when you’re finished. Get a bucket of clean, warm soapy water, dip a rag into it then wring out the excess. Wash down the entire piece, working in a logical order: top to bot­tom, one section at a time. Make sure to clean out your rag in the soapy water from time to time. Get into every nook and cranny and remember, your objec­tive is to wash, not water-log the piece. This initial cleaning may reveal broken or cracked pieces, or failed joints. Before moving onto the next step, carry out any necessary repairs.

Step 3 – Remove Old Polish or Wax

If the piece has been around for any number of years, its finish has likely been smothered in countless layers of built-up wax and polish that need to be removed. A turpentine-soaked rag you’ve wrung out is just the ticket. As you did in the initial cleaning, things go best if you proceed methodically, working on only one section at a time. Rub down the entire area with the rag, refreshing the turpentine whenever the old polish or wax appears to be smear­ing around rather than coming off. As each area comes clean, wipe it down with a fresh rag. Don’t be skimpy with your rags as they’re far less valuable than your time.

Step 4 – Revival

With the finish type identified, the ini­tial cleaning out of the way and any old polish or wax removed, you’re ready to revive the finish. Here’s where knowing what type of finish you’re dealing with comes into play, in a big way.

Reviving an Oil Finish.

Regardless of the oil that was originally used, be it tung, teak, Danish, hemp, or whatever, any other oil may be applied success­fully. Thin the oil of your choice (I prefer hemp oil, incidentally) 50/50 with clean turpentine and apply it liberally with a rag or brush, one area at a time. Once it has become tacky, wipe off the excess with a clean rag and allow it to dry over­night. Using unthinned oil, apply as many additional coats as the wood will soak in, or until the desired effect has been achieved. Now proceed to Step 5.

Reviving a Lacquer Finish.

Start first by lightly abrading the finish with P220 sandpaper. Follow the #1 rule of work­ing with sandpaper – rub only with the grain so that any scratches will appear to be grain marks. Vacuum off the piece to clean it and then fill a clean jar half way with lacquer thinner. The idea here is to brush on a thin coat of lacquer thinner, causing the old lacquer to reactivate and be spread, just as it did when it was first applied long ago. Any scratches or blem­ishes should disappear before your eyes. Keep your brush wet at all times and move from wetted to non-wetted areas until all areas of that section and all other areas have been renewed. Proceed to Step 5.

Reviving a Shellac Finish.

Shellac, like lacquer, is prepared for revival by a light sanding, followed by a thorough vacuuming. Mix four parts of dena­tured alcohol with one part of shellac in a clean jar and mix completely. Brush this concoction onto the finish, working only one area at a time. This should dis­solve the old finish somewhat and cause it to be revived. Wait at least a few hours to see how well things are coming along. If it appears that the finish is not yet revived, or if the old finish was crackled, odds are that you’ll need to do a second and perhaps third application. Proceed cautiously and when things are looking fine, move along to Step 5.

Reviving a Varnish Finish.

Unlike oils, lacquers and shellac, today’s var­nishes aren’t easy to revive. If it’s cracked, has developed small cracks or has begun to flake, unlike the other fami­lies of finish, a new coat won’t simply melt into the old. Short of abrading sur­face scratches and adding some new life into the old finish with oil, little else can be done without resorting to refinishing.

Step 5 – Protection

With the finish now revived, regard­less of the family of finish, you need to finish off by adding a layer of protec­tion. Lightly load a clean rag with paste wax (my favourite is beeswax) then go ahead and apply the wax, using a cir­cular motion. The objective is to apply a thin coat of wax to every area. Work in a logical order, covering one section at a time. Give each section approxi­mately five minutes to set up, then take a fresh cloth and buff gently, using that same circular motion you used to apply the wax. Go onto the next section and once that’s been buffed, return to the first section and polish it well with a clean rag, working only with the grain. Continue working this way until the entire piece has been buffed, then after waiting an hour or so, take a clean rag and aggressively give the entire piece its final buffing. By this time it should have a lovely sheen.

I am convinced that after you’ve tried your hand at reviving the finish on a few pieces of furniture, you will be ask­ing yourself why you had so doggedly stayed with refinishing methods over the years. Reviving brings back the fin­ish with so much less effort, faster and less expensively. Why, with the money you save, you can probably afford to splurge on that new tool you’ve had your eye on for quite some time. It just doesn’t get any better than that to my way of thinking.
