Cut the remains of the plastic side out with a handy saw, so the frame was ready for a new BB.
For your frame, would 100% check that you have an English tread BB, not an Italian, just measure the shell, English will be 68mm, Italian 70mm; and get some quality tools, there are plenty out there, alternatives to Park, include VAR, Cyclo, Cyclus, Pedros, Campagnolo and plenty of others.
Thanks for your input! The frame is a late 90s Bianchi, so it should be 68mm. I have worked on 3 Bianchis from the era and they are all 68mm.
My LBS has a full set of Park Tools, but they usually use the Chinese ones first as they are disposable. A set of alley keys cost under $10, and the design is a direct copy of the Pedro set (made with pot metal).
The freeze spray sounds like a great idea, but it may be hard to get in Hong Kong.
I have searched the forum and heard caustic soda/lye/NaOH is safe for titanium, but this website says otherwise:
