We already mentioned almost three methods by which you can clean your air compressor tank. The first one is manual where you just open the drain valve so all the extras will leave the tank space. Then there is also an electronic method by which you need to replace your manual valve with an automatic one. One thing more which you can use is an Evapo-Rust formula. It is a water-based and environmentally safe solution to remove rust. Specifically, for those who are facing rust issues in their tank. Lastly, we have guided you to a hydraulic cleaning system which is done with chemicals.
