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.
Silicone-lined metal might work. Not directly exposed, not flimsy like plastic, and with a rubberized grippy texture.
