Glad to hear it’s all going well!
The steam definitely takes some getting used to, I’d been steaming on the Bianca for a long while before I got the LM and yeah, still redecorated a corner of the Kitchen on initial attempts. I’ve gotten to the point where I can keep things under control in a 350ml pitcher. Starting with the nozzle just about touching the surface of the milk with the pitcher about half full.
With the milk drying on the wand, I wipe it down before purging after steaming milk, then wipe again after. I find purging immediately will ‘bake’ the milk on.
Having said that we use Oatly Barista exclusively which I must admit seems much easier to clean presumably due to the high water content.
