Metal fences, gates, and railings are robust, but they need to be cleaned regularly to prevent dirt, rust, and deposits and to ensure their longevity.
Metal surfaces can usually be cleaned easily with mild detergent and a gentle brush. For stubborn dirt or rust, special cleaning agents and a subsequent protective coating are needed.
ELEO offers various metal fences, such as the Lucca fence, as well as matching garden gates, which retain their high-quality condition and appearance for a long time with regular maintenance.
Metal fences, gates, and railings are generally very robust and easy to care for, but they still need to be cleaned regularly – especially if the metal is uncoated. Dirt, deposits, and rust are not only unsightly but can also affect the stability and durability of the metal.
Our guide will show you how to clean metal quickly, easily, and effectively. With a little regular maintenance, you can keep your metal fence panels, railings, and gates in good condition.
First, remove loose dirt: Brush loose dirt such as leaves, dust, and cobwebs from the metal parts with a broom or brush.
Then rinse the metal with a garden hose to remove finer dirt and dust.
Step 2: Cleaning
Now choose a cleaning agent suitable for the material of your fence, railing, or gate. For most types of metal, mild soapy water is sufficient. Avoid using harsh cleaning agents, as these can damage the metal.
Apply the cleaning agent to the metal using a sponge or brush.
Scrub the metal gently with the sponge or brush to remove dirt and grime.
After allowing the cleaning agent to soak in for a short time (see instructions on the packaging), rinse it off thoroughly with a garden hose.
Finally, dry the metal with a clean cloth to prevent water spots.

Frequently Asked Questions about Metal Cleaning
Can you clean metal with vinegar?
Whether you can clean metal with vinegar depends on the type of metal. On stainless steel, vinegar effectively removes fingerprints, stains, and light discolouration. Vinegar dissolves tarnish and verdigris on copper. On aluminum surfaces, vinegar removes oxidation. On brass, vinegar can be used to remove tarnish. Important: Always dilute vinegar heavily with water!
How do you clean metal before painting?
Before metal can be painted, loose dirt particles and paint residue are removed from the surface. Then the metal is degreased with a cleaner and subsequently sanded. If the metal is rusty, the rusty areas must be treated with a rust remover. Finally, the surface is rinsed with water. After drying, the metal can then be painted.
Can you clean metal with baking soda?
Yes, baking soda can be used as a home remedy for cleaning some metals. It is an inexpensive and environmentally friendly alternative to chemical cleaners. A baking soda and water mixture is suitable, for example, for stainless steel, copper, aluminum, and brass.
