How To Clean Metal Garden Furniture

1)    Remove surface dust and dirt

Before you get water involved in this cleaning project, you’ll want to get rid of any dust, grit, and grime that is on the surface of the furniture. This accumulates easily whilst furniture isn’t being used, but it is easy to get rid of.

Take a stiff brush and use it to agitate any dirt off the metal furniture. Use this on an inconspicuous area before using it on visible parts of the furniture so you can be sure it will not scratch the metal.

2)    Use a gentle cleanser

Before going in with the ‘hard stuff’ (if it is necessary), you should use a mild cleanser like dish soap. Dilute it in a bucket of water and use brushes and cloths to give your furniture a good scrub, taking care to get into all the nooks and crannies. An old toothbrush can be useful to get into tight spots. This should be enough if you regularly maintain your furniture.

3)    Soak the furniture

If you are really struggling to get the dirt off, soak your furniture in water for a few hours and come back to it. This should be enough to remove any stuck-on grime.

4)    Leave to dry

The last step in how to clean metal garden furniture is to simply leave it to dry. If it hasn’t been affected by rust, use a rust-prevention spray to keep your furniture in prime condition. Make sure your furniture is bone dry if you are planning on putting it into storage and use a tight-fitting cover to protect it from any damage.
