switching inks on a 2200

[bwana]

I have an epson 2200 that has been dormant for a few months and want to use it with UT7 inks. Instead of wasting ink on cleaning cycles, I thought about buying cleaning cartridges and using them first. Anyone here ever use them before? How many times do you clean with them? Can you store them in plastic bags afterwards and reuse them when you switch to OEM inks?
