In theory, no. In practice, yes. If you want to follow the “theory”, the link is pretty cheap.

Note that link is only for 11 speed. All of the others listed from 6 to 12 speed are “supposed” to be singl use only. Most links are supposed to be used only once.

I stand corrected. However, in my defense, only one of the links is marked “reusable” like the 11 speed chain. You have to read all of the descriptions to find out which are reusable and which aren’t. And, as I said above, most links from other companies are meant for a single use. They can be reused in practice but the manufacturers say they are only good for a single use.

Don’t be fooled into thinking that Simple Green is more environmentally friendly. You’ll need much more Simple Green to do the same job. While you can use about 1/2 cup of mineral spirits to clean a chain a dozen times, you’ll need more like 2 cups of Simple Green to clean one chain. Plus you’ll need to remove the Simple Green before you relubricate the chain. That means 2 to 4 times the amount of Simple Green or 4 to 8 cups of water. And then you need to get rid of the water either by heating the chain or by chasing the water with a solvent like alcohol or acetone. You won’t need much of either but you’ll need some. Once you do all the washing and rinsing and drying, you’ve created a much larger volume of waste than if you just used mineral spirits.

Finally, the “smell” isn’t what is toxic. It’s the components. Deodorized mineral spirits contains hydrocarbons which have a low toxicity. Use gloves, of course, but you should use gloves when handling Simple Green as well.
