I have a 50's WFL 18X20 bass drum, that I have had since 1972. It is actually a compacto model drum, but had wood hoops on both ends. Mahogany inner ply and large maple re-rings. I added retractable legs and a Rogers Swivomatic double-tom holder to the drum in 1972. The only frequent maintenance I have done to the drum over the years is to clean the outside wrap and hardware, and occasionally wiped out the inside. The front head and hoop have not been on the drum since 1972.
The drum was played heavy to moderate from 1972 until 1976 while I was in a band at college. From 1977, when I moved to California and lived in apartments then small homes, until 2001, the drum was mostly stored and rarely played. Then starting in 2002, the drum has been played more frequently, now that I have a house with an extra bedroom that is a permanent "music room".
I have noticed that the drum does not "speak" as loudly as it use to.
Current condition: The outside sparkle wrap is faded and cracked. The interior wood is very dry and looks natural, as if there is not a finish on it, but is not cracked anywhere.
How do I ensure that the drum will retain its quality and not deteriorate? Do I clean and refinish the interior? If so, what are the best "cleaners" and "refinish" items to use?
Thanks for any advice from experienced restorers!
