An absorbent insert for drink holders such as coasters and cup holders in vehicles has a size and shape to be retained within the drink holder. Most often, the insert will be a circle having a 2 ¾ inch diameter. The insert is placed within the drink holder. The insert is made of absorbent cellulose material, such as sold by 3M under the name Cellulose Sponge F11, F12, F13. The cellulose absorbs condensation and any additional liquid, such as from spills. Initially, the insert is {fraction (1/16th of an inch but expands upon absorbing fluids. When fully saturated, the insert expands to ½ inch thickness. The increase in thickness is an indicator that the insert should be replaced. The insert is an inexpensive, effective method of absorbing spills and maintaining a clean drink holder.
