Once you begin cleaning with a specific mesh size, you must continue the cleaning process with the next finest mesh size. It is important that none of the intermediate mesh sizes are skipped. Each successive grit size must be used in mesh size order to remove the scratches from the previous mesh size. This finish is finer than the finish which could be obtained even with buffing wheels and without the mess. The Micro-Mesh abrasives can be used either wet or dry, depending on your preference.
Most users prefer to use the sheets dry without any water or other lubricant.
Individual sheets can be washed out and used again. The Micro-Mesh products may cost more than ordinary sandpaper, but it produces finishes ten times finer and lasts 10 to 20 times longer. Grit sizes range from 1500 grit to 12,000 grit. The higher the grit number, the finer the cutting action. The finer meshes are ideal for cleaning and polishing source slits and quadrupole rods.
