Repurposing my Iwaki 70 RLT and started the process today of cleaning it up. The cooling fan and cover are pretty rusted from being in the fish room for the last 7 years. The pump is now going to be used for a closed loop so it won't be exposed to all the moist salty air. Would appreciate any advice of how best to deal with the rust. Not too experienced with this. Thought I could start with a wire brush and see where to go from there. Thoughts?
