Urnex Biocaf™ Milk Frother Cleaning Liquid – Alkaline – 1 L (33.8 fl oz)

The World's First Milk System Cleaner Formulated for Both Dairy & Plant-Based Milks

As oat, almond, soy, and other plant-based milks become standard on café menus, traditional milk system cleaners are falling short. Acid-based formulas can actually curdle plant milks inside milk lines, causing dangerous blockages  and most existing alkaline cleaners weren't designed with plant milk residue in mind. Urnex Biocaf Milk Frother Cleaning Liquid changes that. This next-generation alkaline formula is the world's first milk system cleaner specifically engineered to remove residue and buildup from both dairy and plant-based milks — outperforming other alkaline cleaners in independent testing against all plant milks tested. Made from natural, biodegradable, phosphate-free ingredients, it cleans auto frothers, steam wands, and frothing pitchers effectively and responsibly, with a convenient dosing cap for accurate, waste-free measurement.

FAQ:

What makes Biocaf Milk Frother Cleaning Liquid different from Rinza or other milk cleaners? Biocaf Milk Frother Cleaning Liquid is the world's first alkaline milk system cleaner formulated to effectively clean residue from both dairy and plant-based milks. While Rinza is also an alkaline cleaner from Urnex, the Biocaf formula includes additional chemical agents specifically targeting the unique protein, fiber, and fat composition of plant-based milks — and has outperformed other alkaline cleaners in testing against all plant milks evaluated.

Why can't I use an acid-based cleaner for plant-based milks? Acid-based milk cleaners can cause plant-based milks to curdle inside superautomatic milk lines, creating blockages that are difficult to clear and can damage equipment. The alkaline formula in Biocaf Milk Frother Cleaning Liquid avoids this risk entirely, making it the safe and recommended choice for any café serving oat, almond, soy, or other plant milks.

How often should I clean my milk system? Daily cleaning is strongly recommended to prevent milk proteins, fats, and fibers from drying and hardening into stubborn residue. A consistent end-of-day cleaning routine with Biocaf keeps milk lines clear and ensures every drink starts with clean, fresh-tasting milk.

Is this product safe for the environment? Yes. Biocaf Milk Frother Cleaning Liquid is made from naturally derived, biodegradable, and phosphate-free ingredients. It is one of the most environmentally responsible milk system cleaners available for commercial coffee equipment.

Can I use this on a traditional manual steam wand? Yes. For manual steam wands and frothing pitchers, use the soak method — combine 30 ml of cleaner with 500 ml of warm water, soak for 15 to 30 minutes, then rinse thoroughly with clean water.

How many uses does one bottle provide? At the standard dilution of 30 ml per 500 ml of water, each 1-liter bottle provides approximately 33 cleaning uses — making it a practical and economical supply for daily café use.
