External Terracotta Cleaning & Maintenance

How should I clean terracotta tiles outside?

As per internal, we recommend a mix of dry and wet methods to keep terracotta tiles looking their best.

Regular sweeping is great to remove fallen leaves, berries and dirt - always sweep in dry conditions to obtain the best results.

Wet methods of cleaning can involve a hosepipe alongside a stiff sweeping brush.

We recommend using the Lithofin Power Clean - diluted at a ratio of 1:10 to remove external dirt and staining.

Can I use a pressure washer on terracotta tiles?

We recommend using a Pressure Washer with caution. Spray from at least half a metre away to clear light debris/stains. For older or heavily stained terracotta, manual scrubbing with a soft brush and a specialised cleaner may be more effective.

How do I remove stubborn stains?

For stubborn dirt or stains (such as leaf tannins, berries and spore algae), we recommend using the Lithofin Outdoor Cleaner, designed to remove stubborn dark deposits.


Begin by testing the product on two affected tiles using the below method.
Use a garden sprayer to apply Lithofin Outdoor Cleaner generously to the tiles in undiluted form. The tiles must be completely dry.


Allow the product to work for 2 to 10 hours depending on the stubbornness of the dirt deposits.


Brush the surface with a stiff brush and rinse with clear water. In very stubborn cases, repeat this procedure. Do not rinse Lithofin Outdoor Cleaner onto lawned or planted areas.

Do I need to seal my Outdoor terracotta tiles?

External sealing for terracotta tiles is personal preference. We do recommend sealing terracotta tiles to keep them looking their best, however if you are happy for the tiles to weather in faster it isn't mandatory to seal.
