Not the most exciting of questions, but I had 5 or 6 old Slingerland chrome bass drum lugs that were very dirty and I did the Dawn soak technique which I've used many times with great success.
Life got a little chaotic and I ended up leaving them in the tub for a week instead of the normal 24 hours.
All the grime lifted off as normal, but there is also a noticeable amount of chrome missing, but because they were so dirty before they went in, I'm not sure if they were suffering from this already, or if this can happen if they are simply left to soak for too long.
Another stupid question.... is that simply nickel underneath?
Thx,
Peter
