What You'll Need
To clean and restore metal garden furniture, you won't need specialist equipment. Just gather a few basic items to make the process simple and effective. These tools will help you maintain your furniture with minimal fuss.
Soft brush for removing loose debris.
Damp cloth for wiping down surfaces.
Bucket of warm water with mild washing up liquid.
Dry cloth for drying thoroughly.
Sandpaper or wire brush for treating rust spots.
Car wax or specialised metal wax to seal and protect.
General Cleaning for Metal Garden Furniture
To keep your furniture looking its best, it should be cleaned regularly throughout the year. Aim for three to five cleans annually, increasing the frequency during summer when use is higher. Begin by removing any loose dirt or debris with a soft brush or dry cloth. Prepare a bucket of warm water with a few drops of washing-up liquid, then soak a soft cloth in the mixture and wring out the excess. Gently wipe down the surface of the metal, paying attention to any detailed areas where grime can build up. Rinse thoroughly with clean water to remove any soapy residue and dry completely with a soft cloth before storage.
If your outdoor furniture does get caught in the rain, make sure to rinse it afterwards with water from the hose and dry it fully. Rainwater is naturally more acidic than tap water and can accelerate rusting if left to sit on the surface.
How to Remove Rust Spots
If you notice rust forming, it's important to treat it early to prevent it from spreading. Start by removing any flaking rust or blistered paint with a wire brush or medium-grit sandpaper, working carefully to avoid damaging theunderlying metal. For more stubborn patches, apply a natural solution of white vinegar mixed with salt and leave it to sit on the rusted area for a few hours. This will help break down the rust without harsh chemicals. After soaking, scrub the area clean and rinse thoroughly. To stop the chemical reaction and neutralise any remaining acidity, apply a mixture of baking soda and water, then rinse again. Finish by drying the furniture completely and applying a layer of wax to protect the exposed area.
Protecting Your Metal Garden Furniture for the Future
We powder coat our metal garden furniture to ensure that it lasts as long as possible without rusting. However, accidents can happen and, if your furniture gets damaged, it is necessary to touch up the coating to prevent further damage or decay. To touch up your furniture, start by thoroughly cleaning and degreasing the damaged area with isopropyl alcohol, then lightly sand the area with fine-grit sandpaper (180-220 grit) to scuff the surface for better adhesion.
Apply a matching primer to prevent rust, followed by a touch-up paint specifically designed for powder coating, using a pen for small chips or a spray for larger areas. To protect it further and give it a nice sheen, you can coat it with a thin layer of car wax. After cleaning and drying thoroughly, apply a light, even coat of carnauba-style wax using a soft, lint-free cloth. Finally, buff each section with a separate clean cloth to achieve a touch-dry, lustrous finish that helps repel dirt and moisture.
Things to Avoid When Cleaning Metal Garden Furniture
Whileit may be tempting to reach for strong cleaners or power tools, these can oftendo more harm than good. Harsh chemical cleaners may strip away protective coatings, while abrasive scrubbers like steel wool can scratch the surface, leaving it vulnerable to rust. Pressure washers, although convenient, can forcewater into joints or seams, accelerating corrosion over time.
Tips for Storing Metal Furniture
Proper storage plays a key role in preserving the look and longevity of your furniture. Always clean and dry each piece before storing it. If you have access to a shed or garage, this offers the best protection during winter months. If indoor space is limited, choose a sheltered corner of your garden and use high-quality, breathable covers to shield the furniture from rain and frost. Avoid using plastic covers, which can cause condensation to build up. During the summer, consider using covers overnight or on rainy days, and bring cushions indoors when not in use. These simple steps can make a noticeable difference in preventing wear and weathering.
