Question: what is the best way to wash it ?????
Document: being metal in doesn't break like the glass ones we have purchased before. We like the way it works best.
This is a great little frother. It makes enough froth for about two cups of coffee. After a few tries I found out the key to making the best froth. The key is to let the milk get hot (but not boiling) before trying to froth. This way it froths in just a few plunges. FIY only fill it half way up with milk to prevent overflow with frothing! Enjoy :)
I LOVE IT! !very easy and easy to wash! Keeps the milk warm and enough for a lot of refills!
Unfortunately the use of this milk frother requires the extra step of warming the milk in a microwavable container. Another thing to wash, another step. Oh, well. That said, it works great with parts made to last.
This is very easy to use. I warm it on the stovetop (electric) and then give it a couple pumps. Perfect amount of foam! My only complaint would be the handle. I wish it was designed for stovetop use. No problem though. Just have to remember to use a pot holder. I also wash mine by hand since I use it everyday.
Love this little milk frother. No batteries - and works much faster than those that have them. Nice bit of foam. Just got it, but can see that it should last. (Wish the handle were not heat conductive - say silicone - for heating the milk - but worth it  -Can just use a potholder. )Easy to hand wash with a quick swish (if you don't have a dishwasher - which I don't). Quick rinse and it would be easy in the dishwasher, too.
Great milk frother that works well with almond milk, half and half, and any other milk or milk-type product I have used with it. Puts a latte-like foam on your coffee...probably not great for those who want cappuccino but I am quite pleased and no more batteries or cheap wire whisks that will break on me. Dishwasher safe and easy to hand wash as well.
It is Made in Taiwan, ok with that. No "HIC" brand or anything. No mark line for how much milk to put inside the frother, so I fill up 1/3 and it froths perfectly cold milk. I heat it in another cup, no problem; froth stays firm. Hand wash mine. NO regret on this purchase comparing with other frother in the market and price range. etc. I researched for 2-3 months before decided.
This was a gift for my husband and he absolutely LOVES it! He loves making coffee and tea and special drinks and this is clearly the best frother for the money.
Works great that way.
Answer: I wash it by hand because I don't have a dishwasher. Best to wash the mesh with hot water immediately after use before the milk dries. If it does get dry and you have a hard time cleaning it, you can soak it in some vinegar.
