WhatsApp usSpring is a natural moment to refresh your home and that includes the art and antiques that give it character. A careful, considered clean not only improves how things look but helps prevent long-term damage. When it comes to historic objects, less is more.
Our conservators often stress that dust is the biggest everyday threat. It may seem harmless, but it attracts moisture, pollutants and even pests. Over time, this can lead to staining, corrosion or surface damage. Regular, light cleaning is far safer and far more effective than occasional deep cleans.

How to Safely Clean Paintings
Paintings are particularly sensitive and should always be treated with care. Moisture, in particular, can cause irreversible damage, so avoid water, sprays, wipes or household cleaning products.
Use a soft, dry brush, such as a natural-hair artist’s brush, to gently lift dust from the surface. Work slowly and brush downwards so dust falls away rather than being dragged across the paint.
When checking a painting, look out for:
- Flaking or lifting paint
- Cracks in the paint surface
- Sagging or distorted canvas
- Staining, mould or surface marks
- Loose or damaged frames
If you notice any unstable areas, stop cleaning immediately and seek professional advice. Paintings should also be kept away from direct sunlight, radiators, fireplaces and damp exterior walls to reduce the risk of fading, cracking and movement over time.

Cleaning Framed Artworks
Framed artworks behind glass are often easier to maintain because the artwork itself has a protective barrier. However, the frame, glass and backing still need careful attention, as moisture, dust and poor sealing can all affect the condition of the piece over time.
Use a clean, dry microfibre cloth to gently remove dust and light marks from the glass and frame. Avoid spraying anything directly onto the glass, as liquid can run beneath the frame edge and reach the artwork or mount. If a mark cannot be removed with a dry cloth, apply a very small amount of glass cleaner to the cloth first, keeping it well away from the frame edges.
When checking framed works, look out for:
- Condensation beneath the glass
- Foxing, staining or mould
- Cockling or rippling paper
- Discolouration around the mount
- Loose frames, backing boards or hanging fixtures
Take care with antique, gilded or decorative frames, as these surfaces can be fragile and easily marked. Avoid rubbing raised decoration or using damp cloths on the frame itself.
It is also worth checking that the frame is not placed in direct sunlight, above radiators, near fireplaces or against damp exterior walls. Small checks like these can help prevent fading, warping and moisture-related damage.

Cleaning Antique & Modern Ceramics
Ceramics, particularly fine porcelain, are generally more durable than many other antiques, but they still need a careful approach. Dust regularly with a soft cloth or brush, paying attention to detailed areas where dust can collect.
It is important to consider the surface before cleaning. Glazed ceramics and porcelain usually have a smoother, less porous surface, while unglazed ceramics, porous pottery and damaged areas can absorb moisture and staining much more easily.
When checking ceramics, look out for:
- Cracks, chips or old repairs
- Unglazed or porous areas
- Gilding, enamel or hand-painted decoration
- Loose sections or previous restoration
- Staining, crazing or surface dirt
Avoid using water or household cleaning products, especially on antique, cracked, repaired, gilded, hand-painted or unglazed pieces. Moisture can seep into tiny cracks, old repairs or porous surfaces and cause staining or further damage.Â
If the piece is glazed and appears stable, dry dusting is still the safest routine approach. If marks remain or the surface appears fragile, seek professional advice before attempting anything further.

Cleaning Bronze Statues & Metal Objects
With metals, it’s tempting to polish away tarnish, but this can do more harm than good. Many antiques develop a natural patina over time, which is part of their history, character and value.
Different metals also need different care. Silver, brass, bronze, copper and plated surfaces can all react differently to cleaning products, and some finishes are far more delicate than they appear.
When checking metal objects, look out for:
- Tarnish, corrosion or green deposits
- Flaking, lifting or worn plated surfaces
- Decorative coatings, gilding or painted details
- Loose joins, handles or fittings
- Signs of previous polishing or over-cleaning
In most cases, a light dusting with a soft, dry cloth or brush is enough. Avoid metal polishes, abrasive cloths and household cleaners unless you are certain they are suitable for the object. Over-polishing can remove surface detail, historic finishes and patina. For older, valuable or heavily tarnished pieces, it is best to seek professional advice before attempting further cleaning.

Caring for Outdoor Statues & Garden Ornaments
Outdoor sculptures face constant exposure to the elements, particularly in the UK’s damp climate. Rain, frost, pollution, algae and lichen can all contribute to staining, surface erosion and cracking over time.
Where possible, protect outdoor pieces from prolonged rain exposure. Ensure statues and garden ornaments are well-supported, raised slightly from wet ground, and positioned where water can drain away rather than pool around the base. In colder months, avoid allowing water to sit in cracks or recesses, as freezing can cause further damage.
Algae and lichen are common, but they don’t require aggressive cleaning. Avoid pressure washers, harsh chemicals or scrubbing, as these can damage surfaces and force water deeper into cracks. Regular visual checks and gentle maintenance will help prevent more serious deterioration.

Simple Ways to Prevent Damage
Keeping on top of maintenance doesn’t need to be complicated. A few simple habits can make a big difference:
- Dust lightly and regularly, rather than waiting for heavy build-up
- Keep artworks and antiques out of direct sunlight
- Avoid placing items near radiators, fireplaces or damp exterior walls
- Handle objects with clean, dry hands and good support
- Check frames, plinths and display areas for signs of movement or damage
- Seek professional advice if you notice cracks, flaking, mould, staining or instability
Spring cleaning your art and antiques should never be intensive. It is about consistency, care and knowing when to stop. By using gentle methods and keeping up with regular maintenance, you can help preserve the condition, appearance and value of your pieces for years to come.
