Deep Clean?

Similar post as u/Xef 1 year ago. It got minor traction, but no comments.

I’m in a very similar position to the user. I’ve owned my Volcano Hybrid for almost 5 years. Used almost daily. No error code although I have noticed a drop in fan power.

I contacted S&B, explained that I have no error code, just a drop in fan power, is there like a service/cleaning option. They do not offer anything of the sort. Repairs only.

I have the tool to remove the Volcano shell, I was thinking of lifting up the shell and the inside a light vacuum and clean.

I’ve looked on TY and Reddit for a simple guide on what to do and key areas that may need attention, but nothing about.

Can anyone offer any advice or information?
