There's nothing to clean. They pretty well either work or leak. It's
designed to maintain pressure in the system after a shutdown to aid hot
starting. If yours isn't leaking and your car starts fine hot, then
leave it alone.

Hi,
If you suspect its diaphragm is perforated you can remove the accumulator
and quickly drain it. Then shake it near your ear. If you hear gas
sloshing around in it then it is likely the diaphragm is perforated (gas
trapped on dry side of diaphragm). This is how I found mine to be
defective. Checking my system pressures it "just" fell within spec but the
engine would not start after it resting between 10 to 90 minutes when turned
off from a hot condition. Hope that helps.
