A barista's clogged group head trick changed my whole cleaning game

Last Tuesday I was at this little shop in Portland and the barista behind the counter, this older guy named Marco, saw me eyeballing his espresso machine. I told him my home setup keeps dripping slow and I was about to buy a $60 brush kit. He laughed, walked over, and grabbed a small paperclip from his apron. He straightened it out and showed me how to poke it through the tiny holes in the group head screen, then ran a quick backflush with just hot water and a drop of dish soap. I tried it on my old Breville the next morning and the flow doubled, no joke. It took me five minutes and cost nothing, which honestly makes me wonder how many people throw cash at fancy tools when a bent piece of metal does the job. Has anyone else found a random household item that fixed a stubborn coffee machine issue for cheap? My descaling solution is still collecting dust in the cabinet, so I'm curious what other hacks are out there that skip the store-bought stuff entirely.

That paperclip trick sounds like a quick fix, but I wouldn't trust it long term. Poking metal through those tiny holes can actually scratch or widen them over time, and then you are looking at a real repair bill instead of a $60 brush set. The slow drip probably was not just clogged holes, more likely scale buildup deeper in the machine that paperclip cannot reach. Dish soap can leave residue that messes with the flavor of your shots for weeks. I would rather spend the money on the right tool the first time instead of risking my whole setup to save a few bucks.
