Removing the moulds can be done 12 hours after pouring the concrete. This can be quite a tedious task.

• Use gloves to avoid damage to hands from the concrete when poking them into the holes.
• Pull out all that you are able to retrieve from the orifices either by hand or with a pair of pliers.
• Once you have taken out as much as you can, light a fire in the hole to burn off and get rid of that which is left inside.

Use methylated spirits to facilitate the process of burning the bits you want to get out . However, care must be taken to never put alcohol onto the fire. When the fire gets going, use little pieces of dry wood to keep the fire burning.
