Cleaning Instructions for Fabric Office Chairs
For regular cleaning and deep stain removal, start by vacuuming the whole chair with a brush attachment to get rid of any loose debris. Consult the manufacturer`s instructions on the chair to see if there are any limitations to the kind of cleaner you can use.
For example, with some upholstery, you are unable to use water-based cleaners. If this is the case, use a dry cleaner, which comes both in liquid and powder forms. Put a small amount of the cleaner on a dry cloth (don`t apply directly to the chair). Rub gently but firmly to lift any stains out. Afterward, use a damp (not wet) cloth to remove any residue so that you don`t damage the upholstery.
If you are able to use water-based cleaners, you have a few options. Try using a foam cleanser, which you apply to the whole chair and let sit for a few minutes. Using a brush, scour out any stains. After the chair has had time to dry, vacuum it again with the brush attachment to remove residue.
Another water-based cleaning method is to combine dish soap and water. Mix a few drops of soap and water, and dab the stain with the soap and water mixture and wipe it out. Rinse out any extra soap with a damp cloth.
