Most of the drums I get like these come with white distilled vinegar in them. They are super easy to clean as mainly water will do the trick. They are in excellent condition outside the fact that they attract visible dirt easier due to their color being bright white. These barrels are great for indoor projects such as grey water trapping as well as mixing R.O.D.I. water for aquariums, and they also make great heavy tent weights. Thank you for visiting Houston Barrels.
