I am going to make a water tank that will fit in the bed of my truck for watering my garden. I picked up a 20 gallon plastic tank from a car wash place that originally held car wash soap. It still has some residual soap in it and I want to thoroughly flush it out before using it to water the garden. Any idea on how to do this?
I can run some water through it using a hose but I figure it will foam up and continue to leave bubble/soap residue. Is there something I can pour in the help break down the soap or otherwise cut through it to help flush it out?
