IMO, that process is very old & I used to do that 50 years ago. I now use a Teflon based gun lube that I spray in the lock while moving the key in & out. My previous Polo had a worn ignition lock at approx. 135,000km when I purchased the car. I tried the lube but by then it was too late. On my other cars where I have purchased new or near new, an occasional lube has saved the barrel assembly.
I don't know if lack of lube was your problem or something else.
Just my 2 cents worth.
Understand how it works, troubleshoot logically BEFORE replacing parts.
