Cleaning & maintenance of wood burning stoves

Do Morsø wood-burning stoves rust?

If looked after and installed properly, the stove will not rust. If rust appears on the stove, it is usually because the stove has been exposed to moisture, possibly from the chimney. In summerhouses, the temperature is often very cold in winter and the still air in the combustion chamber can cause condensation on the stove surface. You should therefore leave the valves in the stove open to prevent condensation forming on the oven, which can cause rust. Another good idea is to leave the door ajar when the stove is not being used for a period of time. 

How do I remove dirt from the door glass?

The glass can be cleaned by using an approved glass cleaner. Alternatively warm soapy water and newspaper can be used but only when the stove is cold.

How often should the stove be cleaned for soot and ashes?

The stove needs to be cleaned and serviced fully at least once a year. But naturally depending on how much the stove is used. The baffle is removed from the stove and cleaned up – using a nozzle or a Ash Cleaner. A Ash Cleaner is also suitable for cleaning the rest of the stove. Note that the stove must be cold when cleaned. Soot may appear on the glass if the combustion temperature is too low or if the air controls are used incorrectly. The secondary air controls must be open and the primary air controls closed. The primary air either from the riddling grate or air control are only to be used during the lighting period or when dry wood is put into the stove. Morsø recommends a moisture content in the wood of 16-20%. If you wan to be sure that wood is dry enough, a moisture meter can be purchased from your local Morsø Dealer.

Can I use stove blacking on Morsø stoves?

No, do not use stove blacking on Morsø stoves.

Stove blacking cannot stick to enamelled Morsø stoves; the surface becomes blotched and may flake when the stove is heated.The surface of painted stoves will also become discoloured and blotched if you use stove blacking. Stove blacking should only be used on old stoves that have been ground or sandblasted.

Painted stoves must be painted with Morsø Senotherm paint, and enamelled stoves only have to be washed with hot, distilled water and brown soap.
