How to Clean a Commercial Ice Machine – And Why Scotsman Ice Machine Cleaner & Sanitiser Is a Game Changer

When customers order a cold drink, they expect the ice to be clean, clear and safe. In a busy café, bar or restaurant, the commercial ice machine works non-stop – but it’s often the most neglected piece of equipment in the kitchen.

Without regular cleaning, sanitising and filtration, ice machines can quickly develop slime, mould, scale and bacteria. That puts your hygiene, equipment and reputation at risk.

In this guide from Hospitality Connect, we’ll cover:

• How to clean a commercial ice machine

• Why Scotsman Ice Machine Cleaner & Sanitiser is ideal for the job

• What happens if cleaning isn’t done regularly

• The benefits of using a water filter with your ice machine

Why Cleaning Your Commercial Ice Machine Matters

Inside an ice machine you’ll find:

• Constant moisture

• Changing temperatures

• Mineral deposits from water

• Food particles and airborne contaminants

All of this creates the perfect environment for biofilm (slime), mould and bacteria. If you don’t clean and sanitise regularly, this can lead to:

• Off-tasting or smelly ice

• Cloudy, soft or fast-melting cubes

• Clogged water paths and drains

• Reduced ice production

• Possible food safety issues and health inspection problems

Regular maintenance isn’t just “nice to have” – it’s essential for food safety, equipment performance and customer confidence.

Step-by-Step: How to Clean a Commercial Ice Machine

Always check and follow the instructions in your specific ice machine’s manual. The steps below are a general guide, especially suitable for Scotsman commercial ice machines.

1. Switch off and prepare the machine

1. Discard all existing ice from the bin – don’t reuse it.

2. Turn the machine off and isolate electrical power.

3. Turn off the water supply if the manufacturer recommends it.

2. Remove internal components

Take out any removable parts, such as:

• Water trough

• Spray bar / distribution tube

• Curtain or baffle

• Bin grid (if fitted)

Wash these in warm water with a food-safe detergent to remove loose soil, slime and residue.

3. Descale with Scotsman Ice Machine Cleaner

Mineral scale from hard water can stick to the evaporator, pipes and bin. This reduces heat transfer, lowers ice output and shortens the life of your machine.

Using Scotsman Ice Machine Cleaner:

1. Mix the solution

   • Follow the directions on the label for the correct dilution.

2. Run the clean/descale cycle (if fitted)

   • Many Scotsman machines have a dedicated “Clean” or “Descale” function.

   • Pour the recommended amount of cleaner into the machine’s reservoir and start the cleaning cycle so it circulates through the internal system.

3. Manual descaling (where required)

   • For areas you can reach, use the cleaning solution and a soft cloth or sponge to gently remove scale.

4. Rinse thoroughly

After descaling:

• Flush the system with fresh, clean water as directed in the manual.

• Rinse all removed parts thoroughly to remove any chemical residue.

Rinsing is critical – you never want descaler left inside the machine or on parts that will contact ice.

5. Sanitise with Scotsman Ice Machine Sanitiser

Cleaning removes dirt and scale. Sanitising reduces microorganisms and keeps ice safe.

Using Scotsman Ice Machine Sanitiser:

1. Mix the sanitiser according to the label instructions.

2. Apply the solution to food-contact surfaces:

   • Inside the bin

   • Evaporator surfaces

   • Curtains, baffles and removable parts

3. Allow it to sit for the recommended contact time.

4. Many food-safe sanitisers are designed as no-rinse products – check the label and follow the directions carefully.

Some venues also pour a little sanitiser solution down the bin drain to keep it clean and smelling fresh.

6. Reassemble, restart and discard first batch of ice

• Refit all components once dry or as directed.

• Turn the water and power back on.

• Run the machine until it produces a full bin of ice.

• Discard this first load to ensure any final traces of cleaner or sanitiser are flushed out.

4. Longer equipment life and fewer breakdowns

A clean, descaled and sanitised ice machine:

• Experiences less stress on pumps, valves and sensors

• Suffers fewer blockages and faults

• Typically requires fewer emergency callouts and repairs

Why a Water Filter Is Essential for Your Ice Machine

Even with the best cleaning routine, poor water quality will constantly feed new scale and contaminants into your machine. That’s why a commercial water filter is so important.

How a water filter helps

A good filter system for ice machines will:

• Catch sediment such as sand, rust and dirt before it reaches the machine

• Reduce chlorine and organics that can affect the taste and smell of your ice

• Limit scale build-up by controlling minerals like calcium and magnesium (depending on filter type)

Business benefits of installing a water filter

With the right filter in place, you’ll notice:

• Cleaner, clearer and better-tasting ice

• Fewer scale-related problems in the machine

• Improved energy efficiency and performance

• Lower maintenance and repair costs over the life of the unit

How Often Should You Clean and Replace Filters?

Every venue is different, but as a practical guideline:

• Daily / As needed:

  • Wipe external surfaces and clean up any spills in or around the bin.

• Every 3–6 months:

  • Deep clean and sanitise the machine using Scotsman Ice Machine Cleaner & Sanitiser (more often in high-use or warm, humid environments).

• Every 6–12 months:

  • Replace the water filter cartridge, or as recommended by the manufacturer and your local water conditions.

Keeping a simple maintenance log (dates, products used, who did the work) is a big help when council or health inspectors visit, and it helps your team stay on top of routine cleaning.

FAQ – Cleaning Commercial Ice Machines & Scotsman Cleaner

1. How often should I clean my commercial ice machine?

Most venues should deep clean and sanitise their ice machine every 3–6 months, depending on:

• How much ice you use

• Local water quality

• Ambient temperature and humidity

High-volume or high-humidity sites may need more frequent cleaning. Daily or weekly wipe-downs of the bin and external surfaces should also be part of your routine.

2. Why should I use Scotsman Ice Machine Cleaner & Sanitiser instead of general chemicals?

Scotsman products are:

• Specifically designed for ice machine materials and components

• Food-safe when used according to directions

• Proven to be effective on scale, slime and organic build-up

Using general descalers or harsh chemicals can damage internal parts, void warranties or leave unsafe residues. Scotsman cleaner and sanitiser are formulated for this exact job.

3. What happens if I don’t clean and sanitise my ice machine regularly?

If cleaning is neglected, you may see:

• Slime, mould and scale inside the bin and water system

• Off-tasting, cloudy or soft ice

• Reduced ice production

• Increased breakdowns and repair costs

• Potential food safety issues and negative health inspection results

In worst cases, you could face fines, warnings or reputational damage if contaminated ice makes customers unwell.

4. Why do I need a water filter on my ice machine?

A water filter:

• Protects your machine from sediment and particles

• Reduces chlorine and organic compounds that affect taste

• Helps slow down scale build-up
