What are some non-commercial solutions that work well to remove the
heated and caked milk proteins from the steam tip wand?

Thanks

My solution is that when the machine is off and cold, I pour some
vinegar into a small plastic sandwhich-style bag (one of the snack
size works well). It only takes a couple of ounces. With the entire
assembly on the machine, I just slip the bag over it and then wrap the
bag in such a way that the entire tip and end of the wand is exposed
to vinegar. Then I secure the bag with a clothespin. It may be hard
to picture this, but if you try it you will see what I mean. I let it
sit overnight, and the next morning, all the residue falls right off.
A quick shot of water out the want and very easy wipedown of the wand
and it is sparkling clean.

Neat trick. No need to turn the machine off, the steam wand cools to room
temperature, or nearly so, after having been used.

I clean my wand using a two-hour dunk in enzyme cleaner with the machine on. I
put the cleaner in the frothing pitcher and raise it up to the wand's height on
a little cardboard box. That way, I clean the wand and pitcher at the same time
(it wants to collect milk protein around the bottom rim).

Perhaps I am not quite kosher ... but I find a flat blade works
marvelously (the same blade you would use to scrape stubborn stickers/
tags off windshields/car windows). I suppose a screwdriver might work
too ... seems a little crude though. Just scrape any gunk off, the
clean with water. Works fine for me.

Tap water:
It is well known that heating proteins denatures them which makes them stick
like glue, and so cleaning with hot water can sometimes make it harder than
soaking in cold water (as it comes out of the tap, not refrigerated) for a
few minutes which allows enough of the protein denaturing to reverse and you
can rinse or wipe them off without abrasives. I've found this soaking
softens even some of the hardest caked on milk deposits although some of the
ones that have been baked a bunch of times take a bit longer. It can be a
bit tricky to find just the right blocking to hold up a glass of cold water
up around the tip just so.

This does the same as soaking dirty dishes in cold water. If you've ever
tried cleaning cooked egg off a pan you may have noted that it's much easier
to clean initially after soaking a few minutes in cold water then cleaning
initially still in cold water, later sanitizing and more cleaning with hot
water detergent etc.

In a commercial situation local health codes might also require sanitization
involving heat and or chemicals after such cleaning.

We steam many gallons a day (wiping clean after every use with a green
scrubby/sponge) and use nothing else than a soak in a suitably
balanced cup of boiling water for 10 minutes and more green scrubby,
once a week.

SOAK the wand in hot water mixed with dish detergent for 1 hour. that
way abrasives are not needed.

then wipe clean and flush w/ steam.

wrong :)

we set simple rules:

15 year old - doesn't drink coffee, so no issues - not allowed to use the
gear

11 year old - wants to make good coffee,cleans up after (to the best of her
ability, we must get a stool for her to stand on...)

8 year old - doesn't drink coffee, doesn't show any inclination to use the
gear

6 year old - gets 11 year old, or me to make him coffee

3 year old - hopefully will get the 11 year old or me to make to make her an
espresso...

my baby just wants to dribble on the machine or drink cooled espresso, so we
don't let her near it yet...

so really, my 11 year old has been taught to keep it clean and does... and
dobs the others in if they try to play with the gear.

We usually soak the tip and wand by placing the wand in a glass of hot
water from the steam boiler. Our sponges seem to slide right off of the
junk; looks like we should use something more abrasive like a Dobie pad.
Shoulda' thought more about it...

I vaguely remember ....al advising that soaking steam wands in water was the
biggest cause of sucking milk back into the boiler and nicely lining the
inside of your tank.

His advice, iirc, was aimed at those who clean up the shop, turn of the
machine and leave the wand to soak overnight. the boiler cools and causes a
vacuum and sucks the milky cleaning water back into the boiler.

I reasoned that if the wand was turned off then it shouldn't suck back - but
heck he was Mister Machine (gosh even he was a darn sight more civil than
the current pretender to the throne - and his posts were well reasoned,
informative and interesting aswell!) around here for years back when - so I
never have soaked my wand in waster.

English Ken

Ps the tip comes off and that goes in an eggcup of water if i'm feeling
benevolent. :-)

Are you in a shop or at home? I wipe the wand off immediately after
each use with a damp cloth then shoot a quick blast of steam so the milk
never cakes up. But I'm a home user in control of my own destiny.
