Linen is known to easily absorb water and darken in color, which makes what procedure more difficult?

The procedure that becomes more difficult due to linen's ability to easily absorb water and darken in color is spotting. When a fabric absorbs water deeply, it can lead to a darker appearance, making it more challenging to identify the specific area that needs attention. For cleaners, this can complicate the spotting process because it is harder to ascertain whether a stain is still present or whether the darker area is merely due to moisture absorption. Furthermore, the absorbed water can sometimes cause stains to spread or alter, complicating the overall process of effective stain removal.

While cleaning, drying, or staining also have implications with water absorption, the immediate visual cue and identification of problem areas in spotting are primarily impacted by the color change associated with wet linen. Hence, pinpointing and treating specific spots becomes less straightforward, emphasizing the unique challenges presented by linen's characteristics.
