there are two basic long term storage procedures
1- you cover it , close everything and every now and than you tow it - engine runs and move surfaces eventual you have to fly it a bit
2- everything gets drained - all oils all water - it will be stone dry - tires are a write of, this is ultimate long term storage and needs a large inspection to get back in service 2-3 month time before the aircraft moves with power and needs also ground runs and a test flight
beside parking it’s a expensive way of keeping it
