Put on a pair of grip-style gloves. Roll the chair to a clean area and then lay it on its side.
Attach a crevice or brush tool attachment to the hose of your vacuum and vacuum the rollers. Pull tough debris such as wrapped hair from the wheels by hand or with tweezers. If the rollers feel sticky, wipe the wheels with a lint-free microfiber cloth dampened with water or a commercial household cleaner and then wipe dry.
Vacuum the area where you regularly use the chair. Set the chair upright and then return it back to its original position.
Fill a sink or basin with warm water. Put on your gloves and lay the chair on its side.
Grasp the first roller and pull it straight out from the chair base. If the locks into the slot or is screwed on or bolted, flip or press in on the tab, lever or other locking mechanism or remove the screw or bolt holding and then pull it from the base. If you're dealing with a difficult to remove one-piece assembly, loosen it by lightly tapping it with a rubber mallet and twist it free.
Repeat the removal process with the other rollers.
Wipe the dirt and debris from any metal parts with a few drops of lubricant on a cloth; wipe other parts with a water-dampened cloth. If you're dealing with a one-piece assembly that you can't break down into individual pieces, swish each piece around in the basin of warm water instead to loosen dirt and other debris, shake and wipe away excess water and then air dry.
Place a large piece of cloth or butcher paper on the floor near the chair.
Reattach the wheels to the chair base by simply reversing the process used to remove them. When finished, lift the chair up and roll it back and forth on the cloth or butcher paper about five or six times to pick up any oil splatter before returning it to its original position where you use it.
