Frequently Asked Questions
Which coffee machines is Acto Anti-Calc compatible with?
Acto Anti-Calc is a universal descaler for fully automatic and manual espresso machines, capsule and pod brewers, drip and filter coffee makers, and electric kettles. It works the same way as the manufacturer-branded descalers most machines specify. Always follow the descaling steps in your machine's manual, since some brands require a specific program or rinse count.
How do I use the 100 mL Acto Anti-Calc bottle?
Pour the whole 3.38 fl oz (100 mL) bottle into the empty water tank, top it up with fresh water to about 1 liter, and run the descaling program or brew the mixture through in stages. When the tank is empty, rinse it and flush the machine with at least two tanks of clean water before brewing coffee.
Is Acto Anti-Calc safe to use and store at home?
The lactic acid formula is biodegradable and designed to be safe for the seals, pipes, and heating elements of coffee machines, but it is still a cleaning product. Keep it out of reach of children, avoid contact with eyes and skin, rinse the machine thoroughly after use, and never drink the solution. Store the closed bottle upright at room temperature.
How often should I descale, and which pack should I choose?
Most machine makers recommend descaling every 2 to 3 months, or monthly in hard water areas, or whenever the descale indicator lights up. Since each 100 mL bottle is one cycle, a Pack of 3 covers a typical year with normal water and a Pack of 6 covers hard water or a busy household. Single bottles suit occasional use.

Works great. I use it for my Nespresso machine to clean it. I used to order from their website and would pay double for a one time use. So I decided to check out amazon and different brands. I compared the ingredients and everything matches, it provides me with the same use as the one I used to order from Nespresso double the price for a single use. It is easy to use, and a great value for the money. I will order again. You receive 2 bottles 8fl oz and each can be used 2 times. So out of the 2 bottles you will get 4 uses. Usually descaling is done twice a year, so I am good for 2 years. Saved money as well while using this product.
I have very hard water and this descaler compound is a must. It works very well. I use it on a once a month schedule.
Works well!

Does a great cleaning of my Kureg coffee maker.
Muy satisfecha con esta compra. Excelente calidad, fácil de usar y llegó a tiempo. Lo recomiendo totalmente.
I was having issues with my RV Blank tank sensors and looked for something stronger. Have used a couple times. Not an unpleasant scent. It was reliable in cleaning and removing the residue inside the tank to get the sensors working again. Fully compatibility and approved for RV tanks and their septic system. Consistency in cleaning the tank was better then expected and durable enough I do this treatment now once every 1-2 months.
Excelente
works well, quick shipping
Would recommend this product.
It's a great product.
Works fast and lengthy to clear coffee makers
Coffee machine was making all kinds of noise when water was heating up. After using the descaling was done noise went way down like it was when first purchased.
Works better than the machine branded stuff. Was surprised to see actual solids in the first pass of descaling. Works great and coffee tastes better. We actually used filtered rain water which is cleaner than bottled water, so surprising to see anything in the descaling outfeed.
100% as expected.
I used this to clean my shower I tried everything, I have extremely hard water, which left minerals and scum that I could never get rid of. This product worked extremely well! I put it in spray bottle and used full strength. Just be careful because it will leave residue on shower floor that is VERY slippery. It cleans up easily, you just need to be careful until it’s gone.
Works as described
I hope it works. No matter how much or how often I Descale..my Keurig machine tells me I need to "Descale". Users write in saying that Keurig needs to make it easier. Something is not working as it should.
It worked once I finally figured out how to descale the darn thing. Took me a bottle and a half, but that was my fault.
Great deal
Great product! Clear instructions and easy to use. Descaled my Breville barista pro very well!
