Nothing can affect the flavor of espresso drinks in your cafe, coffee shop or restaurant as much as a dirty steam wand. Even if the steam wand appears clean on the exterior, proteins from the milk being steamed can get pulled inside of the steam wand. Eliminate milk protein buildup with Rinza Milk Frother Cleaner (02027) from Espresso Supply. This cleaner can be used with traditional steam wands as well as auto-frothers. This dispenses cleaner in ounces and milliliters due to a built-in measuring device. Rinza cleaner is NSF certified and kosher.
