Post is for entertainment purposes only. Zero liability. Never had a connector rust. Silicone damaged or melted the plastic on something years ago. Just one drop of antibacterial dish soap and some medium to hot water. Shake the soapy water mixture, rinse interior and exterior, then dry interior and exterior with a wash cloth or hand towel. Stand cylinder up vertically to dry before storing. I think the plastic being warm from the hot water helps it dry better to some extent.
