tooth bushes can have soft bristles so need to use soft ones for the O ring area.
For top/bottom and side plates I have enev used brass brush to clear rust.
Personally I would not use water dispersant as it is supposed to penetrate and remove water (WD-40 style) unless it it restriced to the roller area.
I have found that the important part (& most difficult) is to clean the inside of the rollers this is where the lube + road grime tend to accumulate. To this end, after cleaning, I manually check each roller.
I have done >22k on my OEM RK chain and no problem once I started putting more effort to get the inside of the rollers cleaned.
