How to remove buildup from outdated wood furnishings

Placeholder while write-up steps load

Q: What is the ideal way to thoroughly clean older wood household furniture that has gummy buildup from the end breaking down and/or cleansing item buildup?

A: When more mature household furniture receives gummy, it is generally the worst about knobs, armrests and edges of tabletops or cabinet doors, due to the fact that is exactly where individuals grip and depart fingerprints. Other periods, the full surface area is sticky, a indicator that cleaning products and solutions have designed up or the end is breaking down.

You’ll obtain assistance online that involves wiping off the sticky stuff with vinegar and drinking water or working with a homemade blend of equivalent elements turpentine, white vinegar and boiled linseed oil.

Jeff Jewitt, a finishing qualified and creator of “Refinishing Furnishings Designed Basic” and other guides on finishing, suggests commencing by putting on nitrile gloves and dampening a cloth in paint thinner or mineral spirits. Rub a little spot in circles, he reported, then change the rag to expose a cleanse spot and go on to the next location.

This remedy will choose off oily grime, aged wax and polish, but it will not clear away h2o-soluble grime, which is often a even larger dilemma. For that, he suggests working with a capful of Dawn hand dishwashing detergent in a pint of lukewarm water.

Carol Fiedler Kawaguchi, a finishing qualified on Bainbridge Island, Wash., and owner of C-Saw (cfkawaguchi.com/csaw), a business enterprise that focuses on restoring antiques, usually skips the step involving paint thinner or mineral oil, and rather of Dawn, she makes use of Murphy initial oil cleaning soap ($4.59 for 16 ounces at Ace Hardware) diluted in warm h2o. The label implies employing ¼ cup, or two ounces, in one particular gallon of water, but for a smaller occupation, you could mix three teaspoons of the cleaner with four cups of water. For hard work, you can double the focus of the cleaner.

It could possibly look counterintuitive to clear picket home furniture with a cleaning remedy that’s so higher in h2o, but try to remember that you are now cleaning the end, not bare wood. The trick, in accordance to Jewitt and Fiedler Kawaguchi, is to avoid saturating the finish or building puddles.

Jewitt takes advantage of a clean up fabric which is moist, not dripping, and he refolds it often to expose cleanse locations. Fiedler Kawaguchi works by using a sponge or a mild scrub pad which is wrung out properly. She rinses the sponge or pad usually in warm drinking water, wrings it out, dips it into the cleansing option and wrings it out again to clean up a new area.

Both Jewitt and Fiedler Kawaguchi propose undertaking a light closing rinse with basic drinking water and a wrung-out, clean up cloth. “The plan is to keep drinking water rinse to a minimum,” Fiedler Kawaguchi said. When she’s finished, she wipes the surface area dry.

If the piece even now feels sticky when it’s dry, the finish alone is probably compromised, and very simple cleansing will not be sufficient.

Fiedler Kawaguchi’s upcoming transfer is to ascertain whether the finish is shellac, a organic resin designed by a variety of insect. Shellac is a prevalent finish on antiques but is uncommon on modern-day furniture, which is commonly coated with lacquer, varnish or polyurethane. Pour a little amount of money of denatured liquor onto the complete, hold out a number of minutes and see regardless of whether the complete is sticky if it is, the end is shellac.

If it is shellac, Fiedler Kawaguchi places on nitrile gloves and goes around the end yet again, this time with denatured liquor on a cloth or smooth scrub pad. When she’s fortunate, this revives the finish adequate and no additional get the job done is essential. “It can at times pull off the gunky stuff without having having anything off,” she reported.

It’s all right to quit at any issue, wait for the area to dry and exam no matter if it’s still gummy. After the sticky things is off, a new coat of shellac can go on if required, mainly because fresh shellac sticks to previous shellac.

If the complete isn’t shellac, she switches to a option which is 50 percent denatured alcoholic beverages and fifty percent lacquer thinner, which will strip off gummy lacquer. Lacquer thinner is a more impressive (and far more toxic) solvent than denatured alcohol, so she is careful to have great air flow. She takes advantage of shop towels to wipe off residue.

If that doesn’t get the job done, she uses Citristrip’s paint and varnish stripping gel ($12.98 a quart at Household Depot), which gets rid of quite a few finishes, including paint, varnish, polyurethane, lacquer and shellac. Wearing nitrile gloves thick more than enough to stand up to strippers and doing work exactly where there is ample air flow, she applies the stripper with a paint brush and waits for the finish to soften, which can consider 30 minutes to 24 hours. The floor will have to also be coated with plastic overnight, so the stripper doesn’t dry out.

She then works by using a nylon scraper — in no way a steel a single — to get rid of most of the residue. She gets the rest off using a 3M weighty-obligation stripping pad ($2.98 for two at Home Depot) with a minor paint thinner or turpentine, as well as shop towels.

For a ultimate rinse, she makes use of paint thinner or turpentine. (She avoids water, mainly because the surface is bare wood at that place.) As soon as the surface area is dry, which can consider a while immediately after paint thinner is utilized, it is all set for an oil-based stain or finish. For shellac, lacquer or a drinking water-dependent stain or finish, it also requirements a ultimate cleaning with denatured alcoholic beverages to eliminate the oily residue from the paint thinner.
