Mould in your log cabin will ruin the charm and quaintness along with taking away the visual appeal.

The solution to this problem is to clean your logs routinely. This is a sure-fire way to restore and protect the structural integrity of your cabin.

Logs can be cleaned using a simple solution of liquid dish soap, bleach, and water.

What you’ll need:

  • Bucket
  • Warm water
  • Bleach
  • Liquid dish soap
  • Gloves
  • Protective goggles
  • Spray bottle (for treating interior logs)
  • Respirator (for treating interior logs)
  • Portable water pump (for treating exterior logs)


First, you will need to create a solution composed of 1 part bleach and 1 part water. Next, add 1 tbsp of liquid dish soap to each gallon of bleach solution.

Note that a gallon of this mixture can treat a 400 sqft area that has a moderate amount of mould on.

Ensure that you mix the solution in a well-ventilated area and are wearing gloves and eye protection.

When working on the exterior logs, spray them with a garden hose to rid all of the logs of dust and dirt. Make sure you protect vegetation that may be nearby the cabin by spraying it with water.

Apply the blach solution to the logs, using a hand pump if you are treating the exterior logs. Alternatively, if you are treating the interior, use a spray bottle.

After spraying onto the logs, use a stiff brush to scrub and work the solution in. Start from the bottom and work your way to the top.

To rinse the logs, you should begin at the top of the cabin and work your way down. Use a garden hose to rinse the exterior logs and, for the interior, either use a spray bottle or a wet rag and bucket.

To finish, apply a penetrating stain to the logs to make them less susceptible to being affected by mould in the future. Avoid superficial treatments that use varnish or polyurethane as these do not fully seal logs from moisture.
