Is my HOTBIN aeration mesh blocked?3 October 2012 | HOTBIN Composting It is very rare for the mesh aeration plate to become fully blocked, what you may see is the mesh ‘gunk’ up with silt as the liquid fertiliser (leachate) collects/or drains (depending on HOTBIN model) behind the mesh. Do not worry if the mesh plate looks rusty – it is a galvanised. It often looks a rusty colour as the brown leachate dries on the mesh. If in doubt – clean with bleach as above. Below we advise on what to look out for with the aeration mesh on the different HOTBIN models. HOTBIN Mk.1
For the plate to become blocked, it would require a huge amount of silt to build up in the reservoir behind the mesh plate. The design of the base reservoir and mesh plate means any small pieces of slit sink to the bottom and water flows out the mesh plate above the this. If you find the water line very close to the top (20-25mm) of the mesh, it may be fully gunked up and restricting airflow. To clean the mesh dab with a cloth/sponge with soapy water or you can brush this on. If this does not shift the gunk, then try a bit of bleach or vinegar, this will kill the bio film (removing the gunk) the liquid fertiliser will flow out and the air will be able to get into the HOTBIN again. HOTBIN 200l and HOTBIN Mini 100l The mesh on the HOTBIN and HOTBIN Mini is not as visible as it is recessed from the front of the HOTBIN and as the liquid fertiliser is now drained from the screw cap on the right-hand side of these HOTBIN models no liquid should be draining through the mesh to build up silt and cause an airflow blockage.

If this does not shift the gunk, then try a bit of bleach or vinegar, this will kill the bio film removing the gunk. When removing/cleaning this mesh we advise wearing heavy duty gloves as the mesh does have some very sharp edges. You can check out our video on how to clean the HOTBIN aeration mesh here. Note: If the mesh plate is frequently fully blocked, please check your HOTBIN is level. When tipped forward, the water and silt will collect behind the grill not in the reservoir as required. | Forum Email us
