01 Is the Klyyr tube recyclable?
It is aluminum, with an HDPE cap. Whether your recycling program accepts that tube is a local question. Klyyr does not run a mail-back.
02 Should I rinse it?
Empty it. If your program asks you to rinse metal or plastic, do that. If they do not accept the tube, rinsing will not change the answer.
03 Does the cap go in with the tube?
Only if your program wants them together. The cap is HDPE. The tube is aluminum. Many programs treat those as different streams.
04 What about toothpaste tubes that say recycle with the bag?
Those are usually plastic laminates in a store drop-off. One+ is an aluminum tube. Use the instructions for the package you actually have.
