Backflush

Also known as back flushing · retrolavado · backflush detergente

What it is and what sets it apart: Keeps valves/paths free of oils. Does not replace boiler descaling.

At the bar: Blind basket → water or detergent per protocol → short cycles → thorough rinses with no soap left.

Impact on the drink: Impact: cleaner shots and fewer rancid notes in long service.

Technical notes: Use espresso-safe detergent only. Rinse until no foam/smell.

Common mistakes: Household detergent. Skipping rinse. Chemical backflush every shot.
