Clear "pearls" in FX airpump?

[rkr]

I'm almost finished cleaning my FX airpump but I'm wondering what I should do to those clear pearls that are at the recess of the base of the pump? They are quite filthy looking so I assume they absorb moisture and dirt. Should I clean them and heat them up to dry them or something?

Clean them off and put them back in. They're part of the moisture trap.

They seem to be quite greasy and wet, can I use alcohol for cleaning? Perhaps toss them in low temperature oven for a while to vaporize the moisture in them?

Cleaning with ethanol and heating up seems to work.

yup, they are dessicant beads. they absorb moisture. they can be heated to 200°F to drive out the moisture, and be reused nearly an unlimited amount of times. =)
