Water scale residue, or limescale, is a hard, chalky substance that forms when hard water dries.
The residue’s formation also has a direct correlation with water temperature. The hotter the water, the more hard water deposits there will be.
Not only are these deposits unsightly but they can also shorten the lifespan of appliances that use hot water, such as water distillers and kettles.
Fortunately, you can remove this stubborn buildup with a food-grade citric acid product like ACTIVE Distiller Cleaner.

How Limescale Deposits Can Impact Your Health
Hardwater residue can house some pretty nasty things. This includes heavy metals like lead, and ‘forever chemicals,’ which can pose significant health risks.
For example, they can cause acute and chronic toxicity, organ damage, anemia, or worse.
Given that, it’s highly recommended that you remove the residues with a citric acid-based cleaner, like our Distiller Cleaner.
Mineral Residue Impact on Appliance Longevity
Limescale and mineral buildup can cause extra wear and tear on appliance parts, which can ultimately lead to breakdowns.
For example, they can damage the internal components, leading to leaks, valve problems, and even premature appliance failure.
Why ACTIVE Distiller Cleaner Is the Best Option
Our product is made up of food-grade citric acid, a versatile cleaning agent that can be used not only on water distillers but also on boilers and kettles.
Why our cleaner stands above the rest:
- It’s safe to use and doesn’t contain any harmful chemicals.
- It’s highly effective at removing buildup and residue.
- It will help ensure that your appliance works efficiently.
It’s also cost-effective. One pack contains 32 oz. of cleaning powder, which can last up to 20 cleaning sessions.
Other Benefits of Our Distiller Cleaning Formula
Our Distiller Cleaner features a special formula that uses cleaning crystals to bust up and remove scales and residue.
It’s also highly versatile in that you can use it on all types of water distillers, including those made of stainless steel.
It’s also made from food-grade ingredients, meaning it won’t harm the equipment or the water quality.
Comparing ACTIVE with DIY Methods
DIY methods (e.g. lemons, vinegar) may be convenient but they do have their limitations.
While vinegar solutions are great for cleaning water distillers, their acetic acid boils at a higher temperature than water. This means the steam will end up with very little vinegar.
Not only that but vinegar itself isn’t very effective on water spots and can also harm the distiller’s rubber parts.
The same goes for lemons. While they can be used to clean water distillers, they can also create free radicals and take minerals out of the water.
How to Clean Your Distiller With ACTIVE

Before using ACTIVE Distiller Cleaner, you want to first prepare the appliance. Here’s what you need to do:
- Fill the base with hot water from the tap.
- Give the boiling vessel a quick clean using a non-stick, non-scratch cleaner sponge.
- Run the distiller with water and vinegar for 15-20 minutes to clean the condenser and other internal parts.
Using ACTIVE Distiller Cleaner
Once you’ve prepped the machine, you can use ACTIVE to clean the distiller. Simply follow these steps:
- Unplug the device and fill it with hot water (above the mineral line).
- Add 2 scoops of ACTIVE Distiller Cleaner powder to the tank.
- Let the powder sit inside the distiller overnight or for at least 12 hours.
- Lightly scrub the tank (using a soft brush) in the morning before rinsing it with clean water
Tip: If you have a large water distiller (e.g. one with a two-gallon boiler tank), use 3 tablespoons of the cleaning powder to ensure it’s properly cleaned and descaled.
Maintaining Your Distiller In Between Cleanings
Regular maintenance is key to keeping your distiller in tip-top condition. We recommend doing the following:
- Clean the machine after each distillation with a non-stick, non-scratch cleaner sponge.
- Use ACTIVE Distiller Cleaner every 1-2 weeks.
- Use sacrificial alcohol mixtures when needed.
If necessary, you can also soak the small parts in a diluted vinegar solution.
Just be careful with the carbon filter housing, housing holder, and steam valve when you’re putting it all back together.
Keeping a Regular Cleaning Schedule

Try to clean your water distiller once every 3-4 weeks – that will keep it running smoothly. If you use your water distiller every day, it’s best to clean it more often.
Check For Mineral Buildup
Regularly monitoring your water distiller for mineral buildup is just as important as cleaning it.
Remember, minerals like calcium and magnesium can build up over time, affecting the performance of your distiller and the quality of water it produces.
Here are a few signs that you may be dealing with limescale deposits:
- There are white or off-white deposits on the distiller’s surfaces, especially in the boiling chamber.
- The distiller is not working as well as before.
- The distiller water tastes different from before (residue on the heating element can lead to a ‘burnt’ taste).
Aside from regular cleaning and monitoring for limescale buildup, you also want to change the activated carbon filter regularly.
ACTIVE Distiller Cleaner is a powerful and effective solution that will keep your water distiller in tip-top condition.
Not only is it cost-effective but it also features a concentrated cleaning formula that will effectively remove stubborn scale residue, restore the functionality of your appliance, and maintain the quality of your distilled water.

great product and packaging, totaling 2 pounds, but a bit pricey; my experience with citric acid is mainly preventing fruit browning.

To clean lime scale from your steam water distiller, mix 1/4 to 1/2 teaspoon of citric acid with 1-2 cups of water in the container. Let it sit for about 5 hours, then scrub with a yellow foam pad with a green backing for easy removal of the scale.

My distiller had stubbprn hard water deposits, some flaking off and others firmly stuck. After a few applications of this solution, it looked brand new. I boiled it to eliminate all deposits, as the manufacturer recommends. I would definitely purchase this again.

I was shocked at how well this cleaned my kettle! It looked brand new inside after just one heating and soaking.

I use this to clean my water distiller, and it works great! It cleaned the inside thoroughly. Some granules were clumped, but breaking them apart was easy. Highly recommend!

I got this cleaner for my water distiller, which looked terrible after using faucet water. I used tto clean it with vinegar, wrapping paper towels inside, soaking overnight, and scrubbing the next day. Now, I just add hot water and two scoops of this cleaner, and it works wonders—no scrubbing needed. After the next use, a quick spray of vinegar and a rinse gets rid of all residue. It’s quick, easy, and removes the unpleasant odor from distillation.

Excellent for cleaning my distiller. Not letting hard water residue bake on the bottom before boiling makes cleanup much simpler.
