General Sticky vains in turbo
What makes you so convinced they're sticking / stuck? Are you missing power or experiencing a lot of lag or something?
People tend to get very bent out of shape thinking their turbo veins are stuck but I've yet to see a convincing case of them being properly jammed up.
They move hundreds of times a journey so it's not greatly feasible for them to be sat long enough for crud to build up and jam them.
9 times out of 10 it's the vacuum system that drives the VNT mech that fails causing some loss of performance. The system itself should be 'fail safe' so that it fails into high boost mode, so you end up with a fist full of lag before it'll suddenly take off at higher RPM. This is seen as favourable to having the low RPM boost levels only to run out of power and find your AFR going out of whack and a bunch of black smoke because you've riched out the mixture over 2.5krpm. Constant speed driving isn't really affected as you generate such little boost at a constant speed.
I would check that sort of thing out first. You can run an actuator test on it from MultiECUScan I believe - I know you can on the Alfas. Obviously it's an engine off job so you'll run out of vacuum after doing it once. You want around 10-11mm of movement off top of my head.
If you're still convinced turbo needs cleaning best thing you can do is get a recon kit (all the gaskets seals etc) and properly strip it, but you can buy dedicated turbo cleaning products that you fill the thing with, which is akin to the Mr Muscle trick. Just eBay "turbo cleaner".

Should also add that people sometimes mistakenly go looking for a turbo issue with a loss of performance that can be caused by a sticking EGR.
