After ever ride, fork and shock stanchions get wiped and treated with finish line stanchion lube (not available in the uk).
If it’s dirty, hot water and fairy liquid. If the drive is dirty, cleaned with a couple of baby wipes and topped up with squirt lube. If it’s really manky/winter, cleaned with jizer then dipped in silkolene hot wax.
I listen carefully to my bike so I don’t “service” it as such, just sort stuff as and when. Typically grease of choice is silkolene rg2.
Shocks I use float fluid in the rear, maxima for the open bath fork damper and motorcycle engine oil for the spring leg, maybe a bit of float fluid on top of the air spring. Fork service is only once or twice a year. Brake fluid flush is once a year just before riding holiday.
