"If it ain't broke, don't fix it" is an expensive substitute for an ice machine maintenance program.

What you see above is, unfortunately, the inside of a lot of ice machines. We see far too many instances where people have bought ice machines, turned them on, and then just waited for something to go wrong to pick up the phone.


One common misconception we'd like to correct while we have your attention:

Ice machines do not just turn water into ice.

While that is their main job, of course, there are always other processes going on that you need to be aware of when dealing with ice. Namely, the production of scale buildup, and biofilm buildup. Both these processes are unavoidable when dealing with water and fluctuating temperatures. Keep scrolling to learn more about these byproducts of ice making, and how Blejwas can help to ensure your machines run cleanly, and for longer.

What is scale buildup?

The simple answer: the above picture is scale buildup on the internal components of an ice machine.

The complicated answer: Scale buildup is all of the minerals that are naturally (or unnaturally) found in the water we drink. Calcium is the main component in scale, but there are a myriad of other minerals that are dissolved in water. Water will condensate and build up inside an ice machine over time, and as this water sits and eventually evaporates, it leaves behind the previously dissolved minerals.

Why is scale buildup bad? Because calcium will gradually wear away at the components in your ice machine if left untouched. Not only that, but scale buildup acts as a safe haven for bacterial growth, allowing it to survive even if you're flushing chemicals through the machine.

Biofilm Buildup from Untreated Microbial Growth


Untreated microbial growth can cause biofilm buildup, (AKA "slime") where microorganisms, mainly bacteria, grow together in a matrix of polymers secreted by the microorganisms. These biofilm buildups are extremely dangerous and are the main cause of Legionella, a pathogenic group of bacteria, that can be a serious health concern to people. Worse still, biofilms have a shielding effect making disease-producing bacteria including Listeria, 1,000 times harder to eliminate.


Normal cleaning and sanitizing methods like running your machine’s cleaning cycle are not a replacement for scheduled cleaning and maintenance.

To truly eliminate scale and biofilm buildup requires a factory-certified technician to fully descale, clean, and sanitize the components of an ice machine.

 Irregularly or incompletely cleaned machines are at risk of prematurely breaking down and can spread Salmonella, Listeria, E. coli, Shigella, and the Norwalk virus.

Frozen or Not...Ice Can Contain Harmful Bacteria and Viruses


A University of Texas study revealed that Salmonella, E. coli, and Shigella all survived in ice cubes mixed with a cola, scotch, water...and 85 proof tequila!

Viruses also survive in ice cubes, so our foodborne illness leader, the noroviruses (think Norwalk virus), can wreak havoc in the frozen crystals.
