Step 1: Drain the Cistern

To drain the cistern, first turn off the water supply to your toilet, usually found near the base or behind the toilet. Once the supply is off, flush the toilet to empty the cistern of water.

Hold the flush lever down until the cistern stops emptying. If any water remains, use a sponge or cloth to soak it up and wring it out into a bucket.

This step is essential for a couple of reasons. Firstly, it gives you full access to the cistern's interior surfaces without water getting in the way. Secondly, it prevents any cleaning solution from diluting. THis way, you get the best performance out of your cleaners.

Step 2: Evaluate the Inside of the Cistern

Once the cistern is drained, it's time to evaluate its interior. Look for signs of limescale, rust, mould, or any other buildup that could affect the toilet's functionality.

Check for any damages or wear, like cracks, leaks, or malfunctioning components. Spotting these problems early can save you from future headaches and potentially costly repairs.

Pay special attention to the flush mechanism and the float; these are crucial for the toilet's operation and might need extra care or replacement if damaged.

Step 3: Scrub Inside the Cistern

Use a sponge or a scrub brush to clean the tank's interior, targeting any buildup of limescale, mould, or stains.

Our Activated Eco toilet cleaner sheets are perfect for this task. Simply dissolve a sheet in a small container of water to create a powerful cleaning solution, then apply it directly to the areas needing attention.

Their rapid dissolution technology means they get to work quickly, breaking down tough stains and smells, leaving your toilet cistern sparkling clean. Thanks to its plant-derived formula, this is our best septic safe toilet cleaner!

Step 4: Rinse

After scrubbing, it's important to rinse the cistern thoroughly. Use a bucket of clean water to wash away any loosened debris and cleaning solution.

Rinsing gives you the opportunity to check your work, ensuring that all areas are clean and free of buildup. It's a simple but critical step in the cleaning process, setting the stage for the final disinfection.

Step 5: Disinfect the Tank

The final step in cleaning your toilet cistern is disinfection. This is where our Rosalina toilet cleaning tablets shine. Drop one of these tablets into the cistern and watch as it begins to fizz.

Our research indicates that the food-grade citric acid in these tablets changes the pH level, creating an acid environment that breaks down stains and leaves behind a pleasant scent.

Tips for Keeping Your Toilet Cistern Clean

Maintaining a clean toilet cistern is easier than having to perform a deep clean continually. Here are some expert tips on keeping your toilet tank in top condition.

Avoid Chemical Cleaner Tabs

Chemical cleaner tabs might seem like a convenient solution for maintaining a clean toilet tank, but they often contain bleach, which can corrode the internal parts of your toilet. The corrosive properties of bleach can damage metal components inside the tank, leading to leaks or malfunctions.

Instead of using chemical cleaner tabs, opt for non-bleach alternatives that are safe for the internal parts of your toilet. We at Activated Eco pride ourselves on our options!

Monthly Vinegar Treatment

Our findings show that adding a cup of white distilled vinegar to the tank once a month is a simple yet effective way to keep your toilet tank clean. Leave the vinegar to sit overnight and flush it in the morning.

Vinegar is a natural cleaning agent that helps remove mineral buildup and stains without damaging the toilet's internal components. This monthly treatment can significantly reduce the need for deep cleanings and extend the life of your toilet.

Regular Checks For Sediment and Stains

Checking your toilet tank regularly for sediment buildup and staining is essential, especially if you have hard water or a toilet that isn't used frequently.

Based on our observations, sediment and mineral deposits can lead to blockages and affect the flushing mechanism. By inspecting your tank monthly, you can identify and address these issues promptly, ensuring your toilet operates efficiently.

How often to clean toilet? You can clean your toilet bowl once per week as a standard.
