QuoteDuring my last job, I noticed a special cloth was being used in hospitals to wrap instrument trays prior to sterilization. When unwrapping unused trays, I found this white cloth was soft but abrasive and started to save them for chemical sanding. When asked recently if I found a commercial source for this cloth, I began to look. I knew the hospital cloths were made by Kimberly Clark. The cloth is completely synthetic (contains no pulp or organic materials) and made by Kimberly Clark under a patent. They call the cloth SMS for Spun-Meltdown-Synthetic. Commercially, is it referred to as Hydroknit and sold under the brand name of WypAll. They can be found as X-50, -60, -70 and -80. These are related to the thickness of the cloth. X-50 is the thinnest and X-80 the thickest. X-60 is the same as the hospital cloth I was using and is just the right thickness to work well as a high bite chemical sanding cloth.The best source I found for low quantity (less than 10 boxes, a case) is Office Depot which currently sells them for $9 a box and if you order 3 boxes, they ship for free (a $9 cost saving). Each box contains 126 sheets. One sheet can be cut into 32 2" square patches. One complete phone housing can be chemically sanded with 2 to 4 patches so one box of X-60 is sufficient for 1,000 to 2,000 housings. I use one patch until I quit work and then toss it starting with a clean patch and cotton ball when I go back to the project
