My instrument gets cleaned about every fifty years or so.
There are approximately 1400 seperate removable parts which have to be individually cleaned.
Cleaning tools are :- large quantity of tea, pheasant primary feathers, more tea, long sticks with rags tied to the end, medium length and short sticks with etc., etc., Industrial vacuum cleaner, tea, lead lamps, ladders, tea, mobile phone, (to order the fish'n'chips), newspaper - two types - one to wrap parts together in sets, the other to read along with first item, bowls of slightly soapy water, animal glue, graphite grease, about fifty square yards of clear space, a relaxed attitude to occasional profanity, zinc paint, and a distressing amount of string and duct tape.
Takes about six weeks.
If it's eight weeks to Christmas - nine weeks
If the person who plays the instrument helps - ten weeks.
If the Diocesan Adviser involves himself - twelve weeks.
If there are fewer than 32 days in the month - 14 weeks
