Get most food and beverage stains out by swishing 1 tablespoon of dishwashing liquid with 2 cups of cool water and dabbing the resultant suds onto the stain with a clean, white cloth. Blot until the liquid is absorbed. Repeat the dabbing and blotting until the stain is gone. Dab with cold water and blot dry.
Next, rinse the sponge and use just water to blot out some of the soap mixture. Press dry with a cloth or paper towels. If your beetle dining chair cannot be cleaned with water, try using vinegar or vodka on a cloth to blot the stains. The smell of both the vinegar or the vodka will disappear when the area is dry.
