Most tanks are baffled, and a center-mounted inspection port may not allow access to the baffled sections of the tank. This makes thoroughly cleaning these unreachable areas difficult.
Having the tank out should make things easier - you can scrub what you can reach, then put some solvent (or maybe a strong detergent) in the tank, close it up and slosh it around real well, maybe you'll get at the hard-to-reach areas. Last time we did ours I found some of the filmy deposits on the walls really needed to be physically scrubbed/wiped - we had good access to two of our 3 sections but were unable to do a good job on the center.
