Can I clean an antique sampler?
There is not a great deal you can do to mend or fix the appearance of a sampler once it has become stained and precious samplers should be restored by a professional.
Remove the sampler from the frame and clean the glass with soapy water. Allow it to dry completely. Do not use glass cleaner as it contains chemicals that may cause future damage to the sampler.
The sampler itself may be coated in small dust particles. If your fabric does not appear to be brittle, then you can use a low-suction dust remover to suck up the dust. Small dust vacuums are available from computer stores for cleaning keyboards. Try to hover the vacuum over the sampler rather than touching the fabric or threads.
Carefully put the frame and dry glass back onto the sampler. If your sampler is still looking the worse for wear, then consult a professional cleaning service.
