Hello Rolland.

I work in a tropical country, were there are very few piano tuners, and I
have this problem at least twice a month in my shop.

What you get there is corrosion, that happens not only because of moisture,
heth and moisture help, but you also get a reaction between the lead and
other atmosferic components, once it statrts you cannot stop it, so don´t
bother filing,  they will grow again in a pretty short time. so don´t take
risks, change.
