So, I got a pair of Sennheiser HD 598 a little while back and they must have rubbed against my jeans or rubbed over some ink. There are light blue stains on the headband. Being the impulsive person I am, I took to trying to remove the stains. They are lightened, but not gone.
However, I must have done something the leather did not like because there is a very faint pitting in the leather now; like tiny holes the size of a very fine needle. Is there something I can use to just seal these up so they don't becomes worse in the future?
