It can't be cleaned. If it is exposed to the atmosphere, such as from opening up an AC system, the desiccant will become saturated within five minutes. It your accumulator is malfunctioning, the only thing you can do is replace it - that requires recovery and storage of the refrigerant in the system, and this is why servicing an AC system is not a DIY task.

When Releasing excess refrigerant from a car you are basically left with three options. Release the air using a $1,200 recovery unit, take it to a Certified ASE technician and have them do it right to the car's specific recomendations. The last option I personally do not recomened to anyone which is releasing the refrigerant into the atmosphere. Buy a set of manifold gauges, find the correct amount of refrigerant the car requires and keep releasing until the correct measurment is acheived. All together the illegal way is about $1,165 cheaper unless someone reports you and the EPA slaps the individual with a $10,000 fine.
Reclaim

Always ensure proper recovery and recycling of refrigerants during service.
