How do you clean your cylinders best?

[Brand]

Not sure if this has been asked before, but how do you guys clean you pumping cylinders best? I feel like I am not doing as great of a job as I can be, any tips on how to clean it best?

I rinse my bathmate out with soapy water and brush inside with an old toothbrush and ive got some sex toy cleaner with antibacterial and antifungal properties that I spray into it when it's dry

I use soapy water and a vegetable cleaning brush.

Do you think I'd be alright filling/rinsing an air/vacuum pump cylinder? On the main site I got them from (vacutech acrylic cylinders) it says that any water that enters the device voids the waranty. Kind of worries me I'd get a drop stuck in there before my next pumping session...

I wrap a paper towel around my vegetable brush and turn it as I move the brush up and down to completely dry it.i be.ie e Vacutech is concerned about getting water inside the pump.
