How to Clean Upholstery With Vinegar Safely

Check the tag and the fabric before the bottle

Upholstery sold in the United States usually carries a cleaning code on a sewn tag, tucked below a seat cushion or stapled beneath the frame. The code matters more than any recipe. W means water based cleaning is allowed. WS means water or solvent. S means solvent only, and X means vacuuming and brushing with no liquid.

Vinegar is mostly water, so it belongs only on W and WS fabric. On an S coded piece it can leave a ring or change the feel of the cloth. If the tag is missing, treat the piece as unknown and rely on the patch test below.

Some materials react badly to an acid or to water itself, whatever the dilution. Keep vinegar away from these.

• Leather and suede, which can dry out, stiffen or mark.
• Silk and rayon, which can water spot and lose their sheen.
• Velvet and other pile fabrics that crush or shade when wet.
• Any fabric coded S or X.
• Antique or hand dyed textiles, where the dye may not be stable.

The mix and the patch test

Use plain distilled white vinegar. Colored vinegars, such as apple cider or red wine vinegar, can stain. A common home mix is one part white vinegar to about two parts cool water. For a light odor refresh, a weaker mix is enough. Stronger is not better, because more acid means more risk to dye and more smell to air out.

Dampen a white cloth with the mix and press it on a place nobody sees, such as the back of a skirt panel or the underside of a cushion. Wait until it is fully dry. If the cloth picked up color, or the dry patch looks darker, lighter or stiffer than the fabric around it, stop there.

Step by step

Vacuum the piece first, including the seams, so loose dust does not turn into mud when it gets damp.

• Dampen a clean white cloth with the diluted vinegar and wring it out well.
• Blot the soiled area from the outside toward the center. Do not scrub.
• Turn the cloth often so lifted soil is not pressed back in.
• Blot again with a second cloth dampened in plain water to take the vinegar out.
• Press a dry towel on the area to pull out moisture.
• Dry the whole panel with a fan and an open window, and keep people off it until it is dry.

What vinegar does well, and what it does not

Vinegar is a mild acid. It can loosen light, fresh, water based marks and take the edge off some odors while it evaporates. The vinegar smell itself fades as the fabric dries.

It is a poor match for greasy marks from food or skin, for ink, and for old stains that have already set. It also does not remove what has soaked into the cushion foam, which is where the smell of a pet accident usually stays. Repeating the treatment in those cases adds moisture without adding results.

Safety around other products

Never use vinegar together with chlorine bleach or with a cleaner that contains it. The two react and release chlorine gas, which is dangerous to breathe. Do not layer vinegar over another cleaning product whose contents you do not know. Rinse the area with plain water and let it dry first.

Baking soda and vinegar fizz when they meet, and the fizz is mostly the two cancelling each other out. If you want to use baking soda for odor, sprinkle it on dry fabric, leave it, and vacuum it off as a separate step.

When to stop and call a cleaner

Stop when the patch test changes the fabric, when a ring appears as the area dries, when the stain is oily or older than a few days, or when the cushion is wet through. A professional upholstery cleaning starts with the fiber and the code, uses a method chosen for that fabric, and extracts the soil and the moisture together.

If you do call someone, say what you already used on the piece and where. It helps the cleaner choose what to do next.
