I had the problem with channel imbalance and muffled sound in general. Cleaning with the tool made it even worse. I gave them a good bath in Hydrogen peroxide and WOW, channel imbalance is gone, highs are back and I could clearly see earwax dissolved in (HO)2. I have no idea what long term effect (HO)2 will have on the grill and possibly internals (if it gets too deep) as it is very strong oxidant, but I used 3% solution you can get in pharmacy - I hope it will not do any damage - so far so good.
