Q: What is the ideal way to clean up older wood furnishings that has gummy buildup from the finish breaking down and/or cleaning solution buildup?

A: When more mature home furniture gets gummy, it’s often the worst all around knobs, armrests and the edges of tabletops or cupboard doorways, simply because which is the place people today grip and leave fingerprints. Other situations, the full surface is sticky, a sign that cleansing goods have created up or the finish is breaking down.

You’ll find advice on-line that incorporates wiping off the sticky things with vinegar and h2o, or utilizing a selfmade combine of equivalent sections turpentine, white vinegar and boiled linseed oil.

Jeff Jewitt, a finishing qualified and writer of “Refinishing Furnishings Produced Easy” and other textbooks on finishing, endorses starting off by putting on nitrile gloves and dampening a fabric in paint thinner or mineral spirits. Rub a little place in circles, he claimed, then transform the rag to expose a clean region and go on to the upcoming place.

This therapy will get off oily dust, outdated wax and polish, but it won’t clear away h2o-soluble grime, which is typically a even larger issue. For that, he suggests applying a capful of Dawn hand dishwashing detergent in a pint of lukewarm drinking water.

Carol Fiedler Kawaguchi, a ending pro on Bainbridge Island, Clean., and owner of C-Observed (cfkawaguchi.com/csaw), a company that focuses on restoring antiques, commonly skips the stage involving paint thinner or mineral oil, and in its place of Dawn, she utilizes Murphy authentic oil soap ($4.59 for 16 ounces at Ace Components) diluted in heat drinking water. The label suggests applying ¼ cup, or two ounces, in one gallon of water, but for a smaller sized position, you could mix 3 teaspoons of the cleaner with 4 cups of h2o. For tricky jobs, you can double the concentration of the cleaner.

It may appear to be counterintuitive to cleanse picket home furnishings with a cleansing answer that is so superior in drinking water, but keep in mind that you are cleansing the complete, not bare wooden. The trick, in accordance to Jewitt and Fiedler Kawaguchi, is to stay away from saturating the complete or producing puddles.

Jewitt takes advantage of a cleanse fabric that’s moist, not dripping, and he refolds it routinely to expose clean parts. Fiedler Kawaguchi makes use of a sponge or a gentle scrub pad which is wrung out nicely. She rinses the sponge or pad often in heat drinking water, wrings it out, dips it into the cleansing resolution and wrings it out all over again to clear a new region.

Both of those Jewitt and Fiedler Kawaguchi advocate doing a light ultimate rinse with plain drinking water and a wrung-out, thoroughly clean fabric. “The concept is to continue to keep drinking water rinse to a bare minimum,” Fiedler Kawaguchi explained. When she’s carried out, she wipes the area dry.

If the piece however feels sticky just after it’s dry, the finish by itself is possibly compromised, and very simple cleaning will not be ample.

Fiedler Kawaguchi’s following move is to decide no matter if the complete is shellac, a purely natural resin produced by a form of insect. Shellac is a popular complete on antiques but is unusual on fashionable furnishings, which is usually coated with lacquer, varnish or polyurethane. Pour a compact amount of denatured alcoholic beverages onto the end, wait around a several minutes and see no matter if the finish is sticky if it is, the complete is shellac.

If it’s shellac, Fiedler Kawaguchi puts on nitrile gloves and goes more than the complete yet again, this time with denatured alcohol on a fabric or soft scrub pad. When she’s lucky, this revives the complete ample and no even further do the job is desired. “It can from time to time pull off the gunky stuff with out getting all the things off,” she reported.

It’s alright to stop at any positio
n, hold out for the floor to dry and take a look at no matter if it is continue to gummy. The moment the sticky stuff is off, a new coat of shellac can go on if wanted, mainly because contemporary shellac sticks to outdated shellac.

If the end is not shellac, she switches to a solution that is half denatured alcohol and fifty percent lacquer thinner, which will strip off gummy lacquer. Lacquer thinner is a additional impressive (and additional toxic) solvent than denatured liquor, so she is mindful to have fantastic air flow. She uses shop towels to wipe off residue.

If that does not perform, she takes advantage of Citristrip’s paint and varnish stripping gel ($12.98 a quart at Residence Depot), which eliminates quite a few finishes, together with paint, varnish, polyurethane, lacquer and shellac. Wearing nitrile gloves thick sufficient to stand up to strippers, and doing the job in which there is abundant ventilation, she applies the stripper with a paint brush and waits for the complete to soften, which can acquire 30 minutes to 24 hours. The floor have to also be coated with plastic overnight, so the stripper doesn’t dry out.

She then makes use of a nylon scraper — never a steel one — to get rid of most of the residue. She receives the rest off making use of a 3M heavy-obligation stripping pad ($2.98 for two at Household Depot) with a very little paint thinner or turpentine, as effectively as store towels.

For a ultimate rinse, she works by using paint thinner or turpentine. (She avoids water, mainly because the surface is bare wood at that stage.) Once the surface is dry, which can consider a even though just after paint thinner is applied, it is completely ready for an oil-dependent stain or complete. For shellac, lacquer or a water-centered stain or complete, it also requirements a final cleansing with denatured alcohol to take away the oily residue from the paint thinner.
