I found immersing my Kuku into a nice moist warm penis-purse once every 2 nights, allowing the protective juices to dry-out while sleeping totally bottomless in the cold night air to be very helpful.
Occasionally in the morning, the early bird is also coated with saliva and m0re abalone juices.
That's all the kuku-care I need, other than that, shave/ trim to maintain the hedges and wash it regularly.
Also consider wiping dick after peeing as part of this maintenance too.
