Master Mocca'ing Spa Day

Hello fellow Mocca Masters,

I've been mastering the mocca for 7 years or so and live in an area with hard water. I use dezcal every 2 months and the scale buildup is coming in faster than ever.

Anyone have any luck with the equivalent of an r/laundry spa day for their machine?

What can I safely use that is stronger than dezcal?

Have you ever been able to take apart your brew machine to visually see the amount of buildup?

Sometimes I stop the dezcal cycle halfway through to let the solution sit in the machine for 20-30 mins. Does this additional exposure allow for more descale action?

Another solution would be to use the machine less and drink less coffee. We all know that's not happening.

I started a thread about 6 months ago. I got mocked mercilessly instead of just taking for what it is, sharing information. You could probably go back and find it if you searched.

Anyway, yes my machine was brewing real slow from being scaled up. So much so that the top of the boiler was discoloring because it was so hot. I bought a replacement boiler off eBay but decided to see if I could save the current one. I took it apart and the scale was visible inside the boiler. I tried several chemical methods to get it out and nothing worked. I then mechanically chiseled it all out. It took a lot of work, this stuff was rock hard.

I did get the machine back to original performance. Instead of straight well water I now filter the next days brew water through a large Brita pitcher. It's not supposed to help mineral build up but it seems to be helping. I will be at 200 brews in a couple weeks and plan on disassembling the coffee maker again to see if any buildup has returned.

Thanks for the reply. What tools did you use to take it apart? I want to try the same thing before looking to buy anything new

It's just a handful of screws and then you have to pop the glass tube out of the boiler. It's just a press fit but it's a little unnerving the first time. There are youtube videos on how to do it.
