Quick answer
Three points to begin with.
- Keep works away from direct sunlight, strong lamps, heat sources, vents, damp and rapid environmental change.
- Do not clean a painted surface with cloths, dusters, vacuums, compressed air, water, solvents or household products.
- Do not assume every thangka is safe to roll. Condition, mounting and paint stability must guide storage and transport.

Let condition determine intervention
The care route here is deliberately conservative: control the environment, support the mount and let condition guide storage or transport.
- Control the environment: Begin with light, humidity and change rather than a cleaning action.
- Touch the support: Use the handling section to keep fingers off the painted image and support the structure.
- Escalate carefully: Use the guide's sourced care limits and the individual work record before cleaning, storing or transporting a particular piece. Then follow Explore thangka to compare the current individual record.
Control light and environmental change
Light damage accumulates. It can fade pigments and dyes and weaken cloth, paper and binding materials. Display away from direct sunlight and strong spotlights, and reduce exposure when the work is not being viewed.
Stability matters more than chasing a perfect domestic number. Avoid radiators, heating and cooling vents, kitchens, fireplaces, damp basements, exterior walls with condensation and places exposed to leaks. Sudden movement between very different environments can be as harmful as a poor average condition.
Keep the daily routine simple: look for direct or strong light, keep the work away from heat and damp, check that the support is stable, and note any change before moving it. Preventive attention is easier than correcting damage later.
Handle the support, not the image
Prepare a clean, dry work surface before moving the object. Remove jewellery and anything that could catch a textile edge. Support framed works from beneath with both hands. For flexible mounted works, do not lift from a single corner, rod end or textile flap.
Clean dry hands may provide better control for some sound, non-metallic supports; clean gloves help avoid oils on frames and polished surfaces. The correct method depends on the material and condition. Never allow a glove to create false confidence around loose paint.
Before lifting, clear the route and prepare a clean, dry surface at the destination. Support the object from beneath with both hands, keep fingers and tools off the painted area, and place it flat or upright only in a position designed for that work.
Do not improvise surface cleaning
A cloth, feather duster, stiff brush, vacuum, compressed air or even a very soft brush can dislodge paint that appears stable. Water, household cleaners and solvents can stain, swell or dissolve original materials. Routine care should focus on the surrounding frame, case and room rather than the painted surface.
If you see flaking, lifting, powdering, mould, water staining, tears or distortion, isolate the work from the cause and contact a conservation professional. Do not flatten, glue, repaint or treat mould at home.
Let condition determine storage and transport
Rolling is part of the traditional portability of many thangka, yet repeated rolling can crease textiles and stress paint. An older, flaking or unfamiliar work should not be rolled simply because it is called a thangka. Framed works need corner and surface protection; flexible mounted works need suitable interleaving and a core selected for the object.
Transport packaging should resist moisture, puncture, crushing and shock. A condition check before packing and again after arrival creates a useful record. For valuable, fragile or internationally shipped works, use a specialist packer and confirm insurance, customs documentation and handling responsibilities in writing.
For every move, record the work's condition and the package orientation before sealing, then inspect the same areas on arrival. If the work arrives damp, distorted or unstable, keep it supported and pause unpacking or unrolling until qualified advice is available.
