How to Clean Antique Upholstery Safely

Antique upholstery may contain fragile silk, wool, linen, cotton, leather, dyes, metallic thread and historic stuffing. A method safe for modern fabric can cause irreversible bleeding, shrinkage or fibre loss.

First assessment

Identify the visible cover and inspect seams, fading, powdering, tears and earlier repairs. Treat hidden upholstery layers as evidence, not rubbish.

• Test stability with gentle observation, not wet swabs by default.
• Check loose trims, buttons and fringe.
• Inspect moth or carpet-beetle damage.
• Look for water rings and dye transfer.
• Assess frame movement before cleaning.

Photograph condition before cleaning or movement. Identify all materials and test whether surfaces are stable. Stop if paint, gilding, fibres, veneer or finish begin to move.

Safe treatment and handling

Where fabric is stable, use low suction through a clean screen while supporting the textile. Work systematically and stop if fibres detach. Stain reduction and wet cleaning belong with a textile conservator.

Work from the least interventive option. Use clean tools, controlled suction and barriers that prevent abrasion. Improve environment and remove the cause of damage before attempting cosmetic improvement.

Do not do this

• Using steam cleaners or carpet machines.
• Applying upholstery shampoo.
• Rubbing stains.
• Vacuuming without a screen.
• Removing old covers before documentation.

Monitoring and prevention

Control light, dust, pests and use. Rotate or shade vulnerable pieces and avoid direct skin contact with fragile arms.

Seek professional help for active mould, sewage contamination, fire residues, suspected pesticides, rare textiles, unstable paint or major structural failure.
