Please choose the correct ending to complete the given sentence: Health: [header] How to clean a glass bong [title] Separate all the moving pieces from the bong. [step] Proper cleaning usually involves shaking and some scrubbing, which can damage delicate glass parts if you're not careful. Separate each of the parts--the bong, the slide, and the stem, and set them aside to be cleaned separately.

Ending1: [substeps] You may want to wear latex gloves, as the smell of resin can be hard to remove from your hands. [title] Rinse out the pieces in hot water. Ending2: Setting them aside will also prevent out-of-reach glass shards from scratching the bong. Using electric tongs, remove each piece individually from its current location. Ending3: [substeps] If you have several pieces at once, you're holding them down too tightly. This defeats the purpose of cleaning each piece individually. Ending4: It's best to do this separately so that the pieces don't overcrowd. [title] Place the right violin ring in the disassembled bong.
