PURPOSE:To efficiently wash a liquid flow route with a small amount of a washing liquid by blowing compressed air in the flow route and mixing the same with the washing liquid in the route to bring the washing liquid to a turblent flow state. CONSTITUTION:A washing liquid is brought into contact with the contaminant bonded to the liquid flow routes 11, 12, 13 of piping to remove the contaminant. At this time, compressed air is blown in the flow routes 11, 12, 13 from a cylinder 1 to be mixed with the washing liquid in the routes 11, 12, 13 through injection holes 5, 5' to bring the washing liquid to a turblent flow state and the flow routes 11, 12, 13 are washed. |
