How to Clean a Macerator Toilet

Learn how to clean a macerator toilet correctly with advice and tips from the macerator experts at Saniflo.

Why You Should Clean Your Macerator Toilet Regularly

A macerator is a practical solution for toilets or where traditional plumbing isn’t feasible. It uses a built-in pump and blades to break down waste before pumping it away. However, because of its unique mechanism, cleaning it requires a slightly different approach than a standard toilet.

Regular cleaning not only keeps your toilet hygienic but also ensures the macerator continues to function efficiently. Using the wrong products or methods could cause damage, so it’s important to do it right.

 

How to Clean a Macerator Toilet Bowl

Learning how to clean a macerator toilet correctly is important for keeping it in good working order. For regular toilet bowl cleaning, we recommend using a toilet-safe cleaner, such as a mild disinfectant or a small amount of bleach.

Step 1
Pour a mild disinfectant or a small amount of bleach into the toilet bowl. Avoid pouring excessive quantities.

Step 2
Allow the cleaner to sit in the bowl for 10–15 minutes. This helps break down limescale, bacteria, and buildup.

Step 3
Flush the toilet to allow the cleaner to pass through the macerator system

Step 4
Wipe down the toilet seat, lid, and external surfaces with a standard bathroom cleaner to maintain overall hygiene.

 

How to Descale a Macerator Toilet

In addition to cleaning your toilet, we also recommend occasionally descaling your macerator toilet, especially for units installed in hard water areas. To descale your toilet macerator using the Saniflo Descaler, follow these steps:

Step 1
Disconnect the electrical supply to the Saniflo macerator to prevent it from activating

Step 2
Pour 1 litre of the Saniflo descaler into the toilet bowl and leave for 2 hours

Step 3
Flush the toilet NB: if the toilet/Saniflo is already full of water, DON’T flush the toilet or
it could cause it to overflow

Step 4
Leave for 2 hours

Step 5
Reconnect the power supply to the Saniflo and it should already be at activation level so
will activate as normal

Step 6
Flush a second time to clear any remaining residue

Step 7
Repeat this process every 1-2 months in very hard water areas, 3-6 months in soft water areas

 

How to Descale a Grey Water Pump

The instructions are slightly different for Grey Water Pumps:

Step 1
Disconnect the electrical supply to the Saniflo pump to prevent it from activating

Step 2
For grey water products such as Sanishower+ or Sanivite+, pour 1 litre of descaler down
the wash basin/sink

Step 3
Leave for a minimum of 2 hours

Step 4
Reconnect the power supply to the Saniflo and it should already be at activation level
so will activate as normal, if it doesn’t activate straight away then run the shower or tap
until you hear the unit activate

Step 5
Keep the tap running until you hear the unit operate another 2-3 times and then switch
off tap

Step 6
Repeat this process every 1-2 months in very hard water areas, 3-6 months in soft water areas

 

Maintenance Tips for Macerator Toilets

Use the Right Products
Stick to mild cleaning agents. Small amounts of bleach or disinfectant are fine for regular use.

Descale Regularly
Hard water can lead to limescale buildup inside the unit. Regular descaling every few months helps maintain performance.

Flush Regularly
If the toilet isn’t used often, occasional flushing helps keep the system moving and prevents stagnation.

Watch What You Flush
Only flush human waste and toilet paper. Anything else may damage the blades or clog the macerator.

 

Summary of dos and Don’ts when cleaning your macerator

Dos
✅ Use mild disinfectants or small amounts of bleach
✅ Descale every 3–6 months in hard water areas
✅ Follow manufacturer guidelines for cleaning products

Don’ts
❌ Don’t use strong drain cleaners (e.g., industrial unblockers) as they can damage the system
❌ Don’t use in-bowl rim cleaners or air fresheners that attach to the toilet as they can fall in and get flushed into the macerator
❌ Don’t flush wipes, sanitary products, or foreign objects

 

Conclusion

Cleaning a macerator toilet is straightforward and usually no more time consuming than cleaning a regular toilet. By using gentle cleaning products, descaling regularly, and avoiding harmful items, you can extend the life of your system and prevent unnecessary repairs. A little routine maintenance goes a long way in keeping your macerator running smoothly and efficiently.
