Again, slow learners
Never ever use steel wool on blued or parkerized metal anyone who tells you otherwise is not giving good advice and refuse to change the error on there ways
I hate tell you how many firearms ( collectible) have een destroyed. Because of the statement
"I used 0000 or whatever on my firearms",
or more arrogance like it's my firearm I will do what I want. till they try to sell it and I hand it back, offer 1/3 the value because they ruined the finish of a nice collectible
Everytime someone does this, my un molested firearms increase in value
Don't take my advice,
You will notice my reply, the only reply to your post
Again go slow with a coarse cloth first, will oil /Kroll, this is not a 10 minute job. Brass/bronze only to remove stubborn rust. Again lightly
Probably the best is electrolysis, which is fairly easy for removing rust
Again slow rubbing with vinegar, coarse cloth no need for wool to remove bluing
