If there are no leaks, you can then move outside with your tank to add in the chemicals. Before you get to actually removing the rust, you first need to clean the tank. Dirt, varnish, oil and other debris can collect in your tank over time. To get the most out of your rust remover, these need to be removed first.
A good degreaser works well for this step. If using a cleaning agent made for tanks, follow the directions.
Every once in a while, give the tank a shake to help agitate. If the tank is extremely gunked up, you may want to let the tank soak for a full day. When you drain and rinse the tank, ensure that all the gunk is removed. If some remains, repeat the process with the degreaser. If the tank previously had a liner, that will need to be removed as well.
A good paint stripper that contains methylene chloride works the best. Add a bit of stripper to the tank and seal it up. Slowly turn the tank, ensuring that the chemical finds its way to every part of the tank.
After doing so, safely drain the stripper from the tank. Be very careful to not let the stripper touch the outside of the tank or it may damage the paint job. There is a good chance that not all of the old liner will be removed this first go round. Look in the tank to see if there are any loosened pieces.

Do not go too long with a stronger acid, though, as it can eat the metal of the tank and the agitators if exposed for too long.

It is extremely difficult to remove the sealer once it has cured. Allow the tank to cure for a few days or according to the directions it comes with.
