Can we talk about how long it took to fix my evaporative cooler's mineral buildup?

Honestly, I spent 6 months trying to clean the scale out of my swamp cooler pads with vinegar and commercial descalers, but it kept clogging up every 3 weeks in the summer. Finally broke down and replaced the whole pump and pads last Tuesday, and it took less than 2 hours total. Has anyone else dealt with this nonsense where simple fixes just don't cut it out here?

Muratic acid works but you gotta be careful with it, eats through metal fast if you leave it on too long. Honestly though, sometimes you just have to bite the bullet and swap out the whole setup, pads and all, which stinks but saves the headache.

Wait did the muratic acid actually work or did it mess things up worse? I keep hearing mixed stuff about using it on the plastic parts.

Vinegar for 6 months? Did you try muriatic acid?
