First and foremost, we need to be careful not to expose chemical plastic barrels directly to the sun in normal days, and do not put them directly on the open-air balcony even at night. Because too hot and too cold will accelerate the aging of the plastic. In addition, when we do not use chemical plastic buckets for a long time, we recommend to keep some water as much as possible when storing these items. It does not need too much, about three or four inches deep, and it should be placed in a dark indoor place. When you come back, you can pour out the water and clean it before use.
