I have cleaned them both in the water (both breath holding and SCUBA) and out. When in the water I either use my hand or preferably my hand with a glove on. I also clean them with the air applied. You can instantly see the improved air flow under water if you have a mask on and if enough light penetrates down to depth to see. The white bubbles show up pretty well even if it seems pitch dark when I go down.
Which reminds me, I never got around to cleaning mine last fall when the water was still warm so it looks like donning a wetsuit is in order this spring. Brrrrr. Cold and dark water is not all that inviting. I may just pull them up to the boat instead.
