How to Clean Outdoor Tiles - Simple Steps & Products

Outdoor tiles can transform any garden or patio, providing a stylish, practical surface that stands the test of time. However, exposure to the elements means dirt, grime, and algae build-up are inevitable. Regular cleaning will not only maintain their appearance but also ensure their durability. In this guide, we’ll walk you through the best ways to clean different types of outdoor tiles, along with the best products to use.

Whether you're dealing with porcelain, stone, ceramic, or terracotta, we’ve got you covered with simple steps and expert advice.

Key Takeaways:

Regular cleaning boosts tile durability: Prevents damage from dirt and weather exposure.
Use proper cleaners for each tile type: Avoid harsh chemicals on porous materials.
Sweep regularly: Minimises dirt build-up and the need for deep cleaning.
Seal porous tiles: Protects natural stone and terracotta from moisture and stains and mould spores.

Outdoor tiles are constantly exposed to weather conditions, dirt, and organic growth like moss and algae. If left untreated, this can make your patio or garden tiles look worn and may even lead to long-term damage. Regular cleaning preserves both the aesthetics and lifespan of your tiles.

1. Prevents Staining and Discolouration: Dirt, leaves, and even bird droppings can cause long-term staining if not regularly removed, especially on porous matterials. This is especially true for lighter tiles like limestone or sandstone.

2. Removes Dirt and Algae Build-up: Moss and algae thrive in damp environments, particularly in shaded areas of your patio or garden. Over time, this can make tiles slippery and unsightly.

3. Maintains Slip Resistance: Dirt and moss build-up can compromise the slip resistance of your tiles, making them hazardous, especially after rain.

4. Enhances Durability: When properly cleaned and maintained, outdoor tiles will last much longer. Regular cleaning prevents the tiles from degrading due to moisture, grime, and organic growth, which can wear down their surface over time.

The cleaning method depends on the material of your outdoor tiles. Here’s a breakdown of the best techniques for different tile types:

Porcelain tiles are a popular choice for outdoor spaces because of their durability and low maintenance. However, they still require regular cleaning to stay in top condition.

Steps:

1. Sweep First: Start by sweeping away loose dirt, leaves, and debris. Use a stiff broom for better results, as this will help loosen any ingrained dirt.

2. Mix a Cleaning Solution: Brands like LTP, Lithofin and Fila offer porcelain-safe solutions that are ideal for regular cleaning. Porcelain tile cleaner from LTP is a mild detergent formulated to clean porcelain outdoor tiles. Grimex is also a great product from LTP which will get most stuborn stains from the surface of porcelain tiles. For a basic clean standard washing up liquid will do the job.

3. Scrub: Use a soft brush or mop to scrub the tiles, paying attention to any grout lines where dirt might accumulate. For stubborn marks, you can use a soft-bristle brush or emulsifying pad. For large areas a jet wash with a round rotating head will ensure you don't apply pressure to the grout lines.

4. Rinse: Rinse the area with clean water, ensuring there’s no residue left behind. A garden hose works well, but be sure to direct the water in such a way that it doesn’t push dirt back onto the tiles.

Pro Tip: For particularly stubborn stains, such as those caused by metal furniture rust marks or BBQ grease, you can use a mild bleach solution. However, always test a small area first to ensure it won’t damage the tiles.

Natural stone tiles, such as slate, sandstone, and limestone, add a beautiful, organic feel to your outdoor space. However, stone is porous and can stain easily if not cared for correctly. Therefore, it requires more specialised cleaning methods.

Steps:

1. Brush Away Loose Dirt: Begin by sweeping the area to remove dirt and debris. A stiff outdoor brush will help remove loose soil and any plant matter that may have accumulated.

2. Use a Stone-Safe Cleaner: Always use a cleaner specifically formulated for natural stone. Avoid acidic cleaners (such as vinegar or lemon juice), as they can etch and damage the stone’s surface.

3. Scrub Gently: Use a soft-bristled brush to scrub the tiles gently. For tougher stains, such as oil or grease, use a stone-specific cleaner. You may need to let the cleaner sit for a few minutes before scrubbing. Be careful to avoid wire brushes or anything abrasive, as this can scratch the stone. Again a jet wash with a round rotating head will ensure you don't apply pressure to stones surface a dn protect the grout lines.

4. Rinse Well: Rinse thoroughly with clean water. Use a garden hose or pressure washer on a low setting to ensure all soap residue is gone.

Pro Tip: Sealing your stone tiles after fitting will assist in protecting them from future stains and moisture damage. Sealing also reduces the risk of moss and algae growth. We have a guide on how to seal and maintain natural stone tiles which gives great infomation on this important process.

Terracotta tiles are charming and rustic, but they are highly porous and prone to staining. Without regular care, they can become discoloured and damaged.

Steps:

1. Sweep Thoroughly: Remove surface debris by sweeping. It’s important to ensure there’s no loose dirt before cleaning, as this can cause scratches on the delicate terracotta surface.

2. Create a Cleaning Solution: Use warm water and a pH-neutral cleaner. Avoid harsh chemicals that could strip the natural oils from the terracotta. A good cleaner for terracotta is one that contains linseed oil to help nourish and protect the tiles.

3. Scrub Gently: Use a soft mop or sponge to clean the tiles. Be gentle to avoid damaging the soft, porous surface. Terracotta is more prone to scratches than other tile types.

4. Rinse and Dry: Rinse with clean water and allow the tiles to dry completely. Ensure the area is well-ventilated so that the tiles dry thoroughly, preventing any moisture from being trapped inside the tiles.

Pro Tip: For long-term care, consider sealing terracotta tiles after cleaning to protect against moisture and dirt absorption. Use a specialist terracotta tile sealant to help preserve the colour and integrity of the tiles.

Recommended Products:

- HG Terracotta Cleaner: Specially formulated for cleaning delicate terracotta tiles.

- Lithofin MN Terracotta Sealer: A great option for protecting the surface of terracotta tiles after cleaning.

Grout between outdoor tiles can become dirty over time, especially when exposed to the elements. Keeping grout clean is essential to maintaining the overall appearance of your patio or garden tiles. Here’s how to keep it clean.

Steps:

1. Use a Grout Cleaner: Apply a specialised grout cleaner or make your own using a mix of baking soda and water. A grout cleaner will help lift any dirt, mould, or mildew trapped in the grout lines.

2. Scrub with a Grout Brush: A grout brush or an old toothbrush works well for scrubbing in between the tiles. Focus on areas that are particularly discoloured or stained.

3. Rinse Off: Rinse the area with clean water and let it dry. This will ensure no cleaning solution or dirt residue remains.

Pro Tip: For persistent stains, consider using LTP Grimex for a deep clean.

Split face tiles are a great way to clad all exterior walls, such as garden planters, garden bar walls and even the exterior of your home. As they are made from natural stone they need to treated with a sealer at the fitting stage to protect the surface of the stone, and after this will require minimal maintenance.

Steps:

1. Wipe Thoroughly: Remove surface debris by softly brushing or use a hose to wash down the surface of the stone.

2. Create a Cleaning Solution: Use warm water and a pH-neutral cleaner. Avoid harsh chemicals that can strip the sealer from the surface. Usually the sealer manufacturer will have a cleaner that works with the sealer you have used. You can also use simple washing-up liquid for minimal dirt deposits.

3. Scrub Gently: Use a soft mop or sponge to clean the stones surface.

4. Rinse and Dry: Rinse with clean water and allow the tiles to dry completely. 

Pro Tip: For long-term care, consider sealing split face tiles every 2-3 years to maintain the look of the surface.

Recommended Products:

Using the right products is crucial for effective cleaning. Not all cleaning products are suitable for every type of tile, so it’s important to choose wisely. Here are some of the top recommended products for different types of tiles:

Porcelain Tiles: Use a pH-neutral cleaner such as Fila Cleaner Pro or Lithofin KF Intensive Cleaner for regular maintenance. For stubborn marks, consider using a specialised porcelain tile cleaner.

Stone Tiles: Products like Lithofin MN Outdoor Cleaner and Fila Stoneclean are excellent choices. Always look for non-acidic and non-abrasive cleaners to avoid damage to the stone.

Terracotta Tiles: Use a soft cleaner like HG Terracotta Cleaner that is designed for porous surfaces. For long-term protection, seal the tiles with Lithofin MN Terracotta Sealer.

Split Face Tiles: A gentle cleaner should be used that won't strip any sealer from the surface of the stone. LTP Wax wash or simple washing-up liquid.

Preventative care can reduce the need for deep cleaning. Here are a few tips to maintain your outdoor tiles:

1. Sweep Regularly: Prevent dirt from accumulating by sweeping frequently, especially during autumn when leaves can stain the tiles.

2. Power Wash Occasionally: A power washer can help remove stubborn grime and algae, but be cautious with delicate materials like natural stone. Always use a lower pressure setting to avoid damaging the tile surface.

3. Seal the Tiles: Sealing outdoor tiles, particularly porous ones like natural stone or terracotta, can help protect them from stains and moisture. Sealants also make cleaning much easier, as dirt doesn’t get trapped in the pores of the tile.

4. Address Stains Immediately: Clean up any spills or stains as soon as they happen to avoid long-term damage. This is particularly important for oil or grease, which can be difficult to remove if left too long.
