Can You Clean Mould off Bell Tents?-Boho Bell Tent

Bell tents are a wonderful addition to any outdoor adventure, providing a cosy and unique camping experience. However, along with the joys of camping, bell tent owners sometimes face the challenge of dealing with mould growth on their canvas tents. In this comprehensive guide, we’ll explore the basics of mould, its potential health risks, prevention strategies, and effective methods for removing mould from your beloved bell tent. Whether you’re a seasoned camper or a novice, this resource will equip you with the knowledge you need to keep your canvas tent mould-free and in top shape.

Understanding Mould and Its Implications

Mould, a type of fungi, is a common organism found in various environments. While most individuals with healthy immune systems won’t be seriously affected by mould presence, those with allergies or sensitivities may experience symptoms such as congestion, sore throats, coughs, and more. Furthermore, mould growth on canvas tents is a concern not only due to potential health risks but also because it can lead to canvas deterioration and negatively impact the waterproofing and structural integrity of the tent.

Why Bell Tents Are Prone to Mould

Canvas, the material commonly used for bell tents, is natural and breathable. However, its porous nature makes it susceptible to mould growth, especially if not properly cared for. Mould can take hold on canvas due to two main scenarios: packing up a wet tent and storing it without adequate drying, or exposing the tent to damp and humid conditions over time.

Preventing Mould Growth

Prevention is key when it comes to dealing with mould on your bell tent. While canvas is treated to be mould-resistant, it’s important to recognise that canvas can’t be made entirely mould-proof. Here are some practical steps to prevent mould growth:

Proper Drying - Always ensure your bell tent is completely dry before packing it up for storage, especially after camping in wet conditions. If you’re unable to dry it immediately, make it a priority once you’re home.

Sun and Ventilation - When setting up your tent, choose a spot that receives sunlight and promotes airflow. This helps to naturally discourage mould growth by reducing humidity. 

Dealing with Mould on Your Bell Tent

If mould has already taken hold on your bell tent, it’s crucial to address the issue promptly to prevent further damage. One effective method to tackle mould is the ‘vinegar method’:

  1. Set Up and Dry - Pitch your bell tent in a well-ventilated area and allow it to dry completely. Open all windows and flaps for maximum air circulation.
  2. Brush Off Spores - Using a stiff bristle brush, remove as many mould spores from the canvas as possible.
  3. Vacuum - Run a vacuum cleaner over the canvas to eliminate any remaining spores.
  4. Vinegar Solution - Create a mixture of one part white vinegar to ten parts water. Apply this solution with a soft rag, broom, or brush to the affected areas.
  5. Thorough Drying - Ensure the canvas bell tent is entirely dry before packing up the tent. This step is crucial for preventing future mould growth.

Alternate methods include using a mixture of rubbing alcohol and water (equal parts) or trying natural solutions like lemon, tea tree oil, or baking soda. These methods can be effective in stopping mould spread, but they may not always remove stains.

Reproofing the Canvas

After treating mould, it’s essential to reproof the canvas to maintain its waterproof quality. We recommend products like Stimex or TentMate waterproof and anti-mould spray. Follow the product’s instructions carefully and wait until the canvas is completely dry before reproofing. 

In Extreme Cases

If mould growth is severe and the ‘natural’ methods don’t work, you may need to consider heavier chemical options. However, these should be used cautiously and as a last resort, as they can damage the canvas and its waterproofing. Products like Concrobium Mould Stain Eraser are designed for this purpose but always follow instructions and seek advice if needed.


Caring for your bell tent involves more than just setting it up and taking it down; it’s an ongoing commitment to its maintenance. By understanding the nature of mould, implementing preventative measures, and knowing how to effectively remove mould when it appears, you can extend the life of your bell tent and enjoy countless camping adventures without worry. Remember, a well-maintained canvas tent isn’t just a place to sleep – it’s a cosy sanctuary that connects you with the great outdoors.
