adapters.
Although foam swabs can leave filmy deposits, these deposits are very thin, and
the risk of other contamination buildup on the inside of adapters greatly out-
weighs the risk of contamination by foam swabs.
2 Clean the adapter with the foam swab.
3 Dry the inside of the adapter with a clean, dry, foam swab.
4 Blow through the adapter using filtered, dry, compressed air.
Nitrogen gas or compressed dust remover can also be used. Do not shake, tip,
or invert compressed air canisters, because this releases particles in the can
into the air. Refer to instructions provided on the compressed air canister.
