The 'sloshes' are the easiest multipliers to maintain. I pop the bearings twice a season and soak them in petrol to remove any dirt or oily residue followed by a wash in warm soapy water , rinse then dry with a hair-drier and then re-oil.
To get the bearings out, you may need to make a 'puller'. This is simply a piece of strong wire with a small 3mm hook at the bottom and a bent handle of some sort at the top.
To access the bearing on the handle side, get some tweezers or fine pliers and remove the fine hexagonal spring clip. Hoy a duster or hanky over the reel when you are doing this 'cos the little bu---er hez a habit of flying away in aall directions. Then simply pull the bearing out
On the 'clicker' end, carefully unscrew the two wee screws holding the brass plate that retains the 'clicker mechanism and bearing and pull the bearng out using the piece of bent wire.
As previously mentioned if you place all the components out in the order in which you took them off, it's foolproof.
Thicker oil will slow things up better than any brake-blocks.
