Is it OK to dip SPG's thread into ultrasonic cleaner after you remove it from the hose as long as you make sure it's upright and water is not flooded higher than its neck? And hang it in the air make sure it's dry before reassembling it.
Or do you just use Q-tip to clean it? Wouldn't that leave some cotton inside the SPG and make it leak?
