How to Clean and Maintain an Outdoor Patio Fireplace

There are many types of outdoor patio fireplaces to suit different aesthetics for different houses. In general the maintenance for most outdoor fireplaces is fairly similar. In order for the fireplace to function effectively it needs to be kept dry, ash free, and the chimney needs to be free of debris. Along with these basics, it is important to consider the placement of the fireplace and the materials it is made out of.

Step 1 - Outside Materials

The outer material of the fireplace is what receives most of the damage. It is important to consider just how these materials will hold up to the elements when considering their maintenance. Cast iron will do well from a nice coat of paint. Clay should not be moved as it will easily break. Copper will quickly patina when exposed to rain. The best way to keep an outdoor fireplace looking nice is to either bring it in out of the elements or to seal the outside with either paint or a heavy duty outdoor sealant.

Step 2 - Removing the Ashes

In order for fireplaces to function well and not become a fire hazard, the ashes need to be swept out of the central pit. It is not important to get the interior clean as much as empty. Do not use paper bags or any kind of flammable materials when dealing with fireplace ash. Using a metal bucket and a metal scoop, remove the ashes and allow them to sit overnight before disposing of. Even if it seems there are no coals or open flames, the heat from ashes burns many buildings down each year. These ashes can be composted readily or used to improve the soils in many garden beds. If ashes are removed after each use, there will be fewer stains from rains creating sooty puddles.

Step 3 - The Chimney

Avoiding getting water and debris down the chimney is an important part of outdoor fireplaces. Since the interior of the chimney is not sealed to the same degree as the outer edges, it much more susceptible to damages. Covers can be purchased and then placed over the hole when not in use to greatly diminish any problems. Sweeping the chimney out with a wire brush once a year will also help remove any buildup which could come from materials being burned.

Step 4 - Placement

The best way to minimize cleaning and maintenance on your patio fireplace is to consider where it is placed. High traffic areas cause many issue with the fire pit or chimnea being knocked over. Ashes can become strewn all over the patio or the fireplace damaged. Try to place the fireplace out of high wind areas as well. This will keep ashes and embers from getting caught in the winds and winding up in unwanted places. If the fireplace is not portable and is directly exposed to the rain, a splash guard or protective mat directly outside the fire place opening will keep the deck from being stained with puddles of ashy water.
