What do you have that's not getting cleaned up enough? (or are you just anticipating)
For example, the power switch is difficult to get around the toggle. The miter gauge have that curved slot in it. The sheaves are loaded with gunk and it's so far I can't get in between all the slots. The indentations on the locking handles and lettering are filled with gunk and resin in places, as are the rack teeth on the table tubes. Then there are all the pin, bolt, and screw holes that have sticky grit in them after sanding and stripping.
Some of my issues are stains more than just filth but it all sticks to the parts and has been a challenge to remove. Yesterday I found that Citrus Strip will take rust of tubes (don't worry, I have a gallon of Evaporust).
So far, my best friends have been brass brushes, tooth brush, mineral spirits, a fine wire wheel on my grinder (on its last leg), soft paint removal wheel, scratch awl, and a chip brush. But those brushes are just too wide to get into many places. Maybe I'm going overboard but this is the first time I've ever tried to make a machine not only work well but look good too.
