I think you need to someone with press to remove that spindle hopefully without cracking the headstock
My thoughts on the bearings is stick with the ball bearings or the angular contact ball bearings

Ultrasonic Cleaning looks promising

What Ultrasonic Cleaning Can do

Its Cleans Oil, grease, polishing compound, waxes, cutting fluids, lapping compound, dirt, swarf, residues, resin, silicones, carbon deposition, scale, finger prints, solder flux, plating salts, blood, ink, photoresist, lacquer, paint etc

I believe you are saying your abrasives have embedded in the cast iron

Next time it may be worth consider using Timesaver or Garnet lapping compound (supposed to break down)
Or use a soft lap, abrasive gets embedded in the lap then not the work

Only thing i can think of to get it out is have it hand scraped

I have a P802MA from well know online auction site, after fixing it to a piece of 50mm board (for stability) and adding two 210A MOSFETS(to move the high power load off the main board) one for the bed and one for the hot end, and also a Scrub Surface Hot Bed Sticker (so prints stick to the bed and can be removed)I have been pleased with it

Thread: PLA Filament Breakage

There is very little cost to cutting a meter or two and giving it dip in boiling water. so i see no reason for anyone to just desregard this without testing, it has worked for me

The filament is dry before you bin it , give it a 5 sec dip in boiling water then let it dry
