Blotvättning

Blotvättning is a Swedish term referring to a specific method of cleaning or washing that involves the use of a blotter or absorbent material. This technique is commonly employed in situations where delicate surfaces need to be cleaned without excessive rubbing or scrubbing, which could cause damage. The principle behind blotvättning is to lift or absorb a stain or unwanted substance rather than to spread it around.

The process typically involves applying a cleaning solution to the affected area and then using a clean, absorbent cloth, paper towel, or specialized blotter to gently press onto the area. The blotter absorbs both the cleaning solution and the lifted stain. This method is particularly useful for porous materials like fabrics, paper, or certain types of stone, where aggressive cleaning might lead to disintegration or spreading of the stain.

In conservation and restoration contexts, blotvättning is a standard technique for removing ingrained dirt or specific contaminants from historical documents, textiles, or artworks. The choice of blotter material and cleaning agent is crucial and depends on the nature of the stain and the material being treated. Professionals often test the method on a small, inconspicuous area first to ensure it is safe and effective. While the term originates from Swedish, the technique itself is recognized and utilized globally under various descriptive names emphasizing absorption or lifting.
