Cleaning and maintenance
Purging and wiping the steam wand
Three seconds after every drink. Skipping it is the most common cause of a blocked wand and of milk that will not foam.

Safety
Purge with the wand pointed into the drip tray and away from you. The wand stays hot for several minutes after use. If you are making a drink for someone with a milk or other allergy, treat the wand, cloth and jug as contaminated by whatever was steamed before: one food-safety authority's procedure is to wash the wand in hot soapy water, purge into it, rinse and purge again, and use a disposable paper cloth, and it notes that sanitiser wipes do not remove allergen proteins.
Your equipment’s instructions come first
Whether a tip can be removed for cleaning, and how, varies by machine. Follow the machine's own instructions rather than a general procedure.
Why it works this way
This is the shortest technique on the site and the one with the best ratio of effort to consequence. Milk left on a hot wand dries on quickly, including inside the tip holes where no cloth reaches. A blocked tip delivers uneven steam, which makes texturing unpredictable, and residue inside a warm wand is a hygiene matter rather than an aesthetic one. Purge, wipe, purge again — as a single reflex tied to putting the jug down. A wand also carries milk from one jug into the next: a food-safety team that tested 21 cafés found allergens still on the wand after cleaning at 19 of them, so a wipe and a purge are not enough before a drink for someone with an allergy.

How to do it
Wipe the wand with a damp cloth kept only for that purpose, immediately after steaming.
A cloth used for anything else puts what it was used for onto the wand.
Purge steam briefly into the drip tray.
This clears milk drawn up into the tip as the steam stopped, which is where blockages start.
Soak the tip periodically in a milk-system cleaner, following the product's instructions.
Wiping and purging handle the daily residue; soaking handles what accumulates regardless.
How to tell it worked
Steam that emerges evenly from every hole in the tip, and milk that behaves the same way today as it did yesterday.
If it did not work
What you saw, what to change, and why the change works.
Steam comes out at an angle or from fewer holes than it should
Change: Soak the tip in milk-system cleaner and, if the manufacturer's instructions describe it, remove and clean the tip.
Blocked holes redirect the flow, which changes where the air goes and makes texturing unpredictable.
Common mistakes
Wiping without purging
Milk drawn into the tip dries inside where the cloth cannot reach.
Instead: Always do both, in that order.
Clearing blocked holes with whatever is to hand
A hard point can enlarge or deform the holes, permanently changing the steam pattern.
Instead: Soak first, and clear the holes only with the tool and method your machine's maker gives, with the machine off and the wand cool.
