I’m not sure Home Improvement is the correct sub for this, but I’m looking to replace my dual flush actuators with metal ones instead of these chromes plastic ones that corroded due to the bleach fumes from using bleach bricks in the tanks. I’ve stopped using them, but I still need to replace the actuators or buttons and I want something more robust.
Edit: went ahead and ordered duplicate replacements.

Metal ones will degrade much faster than plastic if you’re putting bleach in the tank. It’s best to just clean the bowl as the tank shouldn’t really need sanitizing.
Exactly, that’s why I mentioned that I stopped using the bricks. I just want more robust buttons to replace the corroded ones, now.
