The practical answer
Cleaning in place is a method decision, not a promise for every curtain.
On-site curtain cleaning is valuable because it can keep the curtain on its track or rod during treatment. That is particularly useful for large installations, fitted interiors, occupied homes and commercial properties where removing many curtains creates disruption.
However, a technician should first inspect the fabric, lining, dye stability, previous damage, staining and installation. A curtain that is brittle from sun exposure, structurally weak or made from an unsuitable specialist textile may require another route.
