   But I suspect what was actually needed was sodium *PER*carbonate! 😫
   https://en.wikipedia.org/wiki/Sodium_percarbonate

   Wikipedia confirms that, in water, percarbonate decomposes into hydrogen peroxide. Which is why it works the same for #retrobrighting.

   But I don't have any percarbonate at home, and it won't arrive before Dec 29 either.

   Moreover, how much would I need to get the equivalent of 12% peroxide? Now I regret not paying enough attention in #chemistry classes! ⚗️
