As the seasons shift and natural light returns, spring cleaning becomes more than a household ritual, it’s an opportunity to care for the objects that hold history, beauty and value. Whether you own a centuries-old oil painting, a mid-century sculpture, or contemporary mixed-media artwork, proper spring cleaning can preserve both aesthetic appeal and long-term integrity.
This guide offers expert-backed advice for safely cleaning and maintaining artwork and antiques without risking damage.

Before You Start
Unlike everyday household items, artwork and antiques are highly sensitive to environmental changes, handling, and cleaning methods. Dust, pollutants, humidity fluctuations and even household cleaning products can cause irreversible deterioration.
Regular, gentle maintenance helps to prevent surface buildup that can degrade materials, protect finishes, maintain value for collectors and reduce the need for costly restoration further down the line.
Before diving into any cleaning process, keep these essential principles in mind:
When in doubt, do less. Over-cleaning is one of the most common causes of damage.
Avoid water and chemicals. Many materials, especially wood, paper and paint, are extremely sensitive to moisture and solvents.
Use soft, dry tools. Microfiber cloths and soft brushes are your safest options.
Test in an inconspicuous area. If you must clean more deeply, always test first.
Know when to call a professional. Valuable or fragile pieces should be assessed by a professional conservator.

Cleaning Oil Paintings
Oil paintings often have a protective varnish layer, some discoloration sits on top but the varnish itself can yellow or trap dirt over time. Surface cleaning can be gently performed at home, but deeper varnish removal treatments require an expert hand.
Use a soft, dry brush (like a sable hair brush) to gently remove dust. Avoid using water or commercial cleaners and never attempt to remove the varnish layer yourself – not only is this unsafe for the artwork, the solvents may be harmful to your health.
If the surface looks dull, cloudy, or uneven, it may need professional cleaning rather than DIY care. In this case, our conservators can help and provide guidance on what can be achieved.

Cleaning Modern Art & Acrylic Paintings
Acrylic surfaces are more flexible but can attract dust due to static. Use a dry microfiber cloth or anti-static brush. Do not apply pressure when cleaning, as acrylic paint can soften and scratch easily.
Avoid cleaning paintings with heavy impasto (raised, thick paint layers) yourself, as although these trap dust easily – they can also be broken when brushed or cleaned at home. These pieces need a professional service, conducted with small cotton swabs.
Some paintings may have been stained by nicotine, resulting in a yellow substance on the surface. This may be sticky or have an odour and should a conservator should be consulted for a safe removal (as seen in the example above).
Cleaning Paper Artworks (Drawings, Prints, Watercolors)
Paper is highly vulnerable to moisture, oils and abrasion, so the surface itself should generally be left alone. In most cases, spring cleaning means focusing on the frame and glazing rather than the artwork.
Dust the glass, keep handling to a minimum, and make sure hands are clean or use gloves when appropriate. Trying to clean the paper directly, even with an eraser or specialty pad, can cause irreversible damage. If the paper needs to be cleaned in any way, consult a professional.

Cleaning Metal Antiques (Silver, Bronze, Brass)
Metal objects can tarnish or corrode depending on their environment, but not every darkened surface is a problem that needs to be polished away. With historic metalwork especially, the finish that develops over time may be part of its significance.
For that reason, a short list is more helpful than a long explanation:
Dust with a soft cloth or brush
Keep away from humid areas and avoid liquids
Never use abrasive pads or harsh compounds
Avoid over-polishing, which can remove historic surface layers

Cleaning Ceramics & Decorative Objects
Glass, ceramics, and many sculptures are somewhat more durable, but they still deserve a careful approach to avoid damage.
A soft cloth is often enough for regular maintenance. When deeper cleaning is necessary, minimal water is usually the safest route and even then it should be kept away from cracks, repairs, joins or old adhesives.
Ceramics with gilt areas or decoration applied on top of the glaze should only be lightly dusted with a dry, soft cloth – exposure to liquid or abrasive techniques may destroy the details.
Antique ceramics should never be soaked casually, since old repairs may be water-sensitive and fine cracks may allow water to seep past the finish, into the inner porous materials.

Cleaning Frames
Frames are often ignored during spring cleaning, even though they collect dust, kitchen residue, and airborne grime just as readily as furniture does. This is especially true for carved, gessoed, or gilded frames, where buildup settles into every decorative detail.
The safest method is simple:
Use a very soft brush to lift loose dust
Clean around the frame rather than forcing dust deeper into crevices
Keep water and household cleaners away from gilded or fragile decorative surfaces

Environmental Tips
Caring for art and antiques is not just about what touches the object directly. The surrounding environment plays a major role in long-term preservation, and spring is an ideal time to reset the space as well as the collection.
Try to focus on the basics: stable humidity, good airflow, clean filters, and protection from direct sun. Relative humidity in the 40 to 55 percent range is generally a comfortable target for mixed collections. It also helps to reduce airborne dust with HEPA filtration and to rotate displayed objects if some areas of a room receive stronger light than others.

When to Call a Professional Conservator
Some issues are better handled early, before they become expensive or irreversible. If an artwork or antique shows signs of active deterioration, cleaning should stop and professional advice should begin.
Watch for signs such as:
Flaking or cracking paint
Yellowed or uneven varnish
Loose joints, tears, or warping
Mold, water staining, or unexplained discoloration
Heavy grime that does not lift with gentle dusting
Professional conservators work with methods designed to preserve both material stability and historical integrity, which is very different from ordinary cleaning.
Spring Cleaning as Preventive Conservation
Spring cleaning is most valuable when it is approached as preventive conservation rather than cosmetic improvement. The aim is not to make an antique look new or make an artwork look freshly produced. It is to protect what is already there—the finish, the patina, the surface, and the evidence of age that gives the object meaning.
From heirloom furniture to contemporary canvases, small maintenance decisions add up over time. A measured, informed approach can extend the life of a collection and reduce the need for interventive restoration later.
