What can cause damage to glazed and polished finishes that is noticeable when soils are removed?

Body oils and abrasives can indeed cause visible damage to glazed and polished finishes when soils are removed. These finishes often have a smooth, reflective surface that can be easily marred. Over time, body oils from skin contact and abrasive materials can create scratches or dull areas. When cleaning, if these soils are stripped away, the underlying damage may become apparent, revealing a difference in texture or shine compared to the untouched areas of the finish. This is particularly noticeable on surfaces that are designed to have a high gloss or polished appearance, where any inconsistency can detract significantly from the overall aesthetic quality. Therefore, being aware of this type of damage is crucial for fabric and upholstery cleaning professionals when assessing the condition of furniture prior to cleaning.
