In some cases, washing with alkaline water may be added prior to the washing with water. Washing of the distillation column for separating and purifying a crude (meth)acrylic acid compound, can be carried out easily. In particular, in a process for producing a (meth)acrylic acid compound, a substance used in a step before or after the distillation column can be utilized to recover a valuable substance, and the distillation column can be efficiently cleaned.
