Methods and apparatus for removing particles from sheet materials, particularly plastic materials that are to be laminated to other materials, are disclosed. The sheet is destaticized, wiped and lightly scraped to dislodge particles from the sheet. The dislodged particles are removed from the sheet by suction. Scrapers with single fixed blades and scrapers with multiple movable blades are used to dislodge particles that are embedded in or adhered to the sheet. The process and apparatus are particularly useful for cleaning sheets of plastic material that are used in laminated glazings having stringent optical requirements.
