blot as much urine up as you can- if it's still wet (doesn't matter) mix vinegar & water in a spray bottle (40/60 or any strong combo will do)- soak entire area. let sit a while then coat with baking soda- let sit again. scrub with hand brush- take up with paper towels.
Hernia mesh is a product which is used in hernia repair. It is made from implant-grade plastics which are formed into a grid which can be used at the site of a hernia to hold herniated organs in place and provide a lattice for new tissue to grow on, effecting a long term repair at the site.
Mesh material is often used in determining the particle-size distribution of a granular material. For example, a sample from a truckload of peanuts may be placed atop a mesh with 5 mm openings. When the mesh is shaken, small broken pieces and dust pass through the mesh while whole peanuts are retained on the mesh. A commercial peanut buyer might use a test like this to determine if a batch of peanuts has too many broken pieces. This type of test is common in some industries, and, to facilitate uniform testing methods, several standardized mesh series have been established. Metal surfaces mechanically polished are designated as having a mechanical finish related to the abrasive used.
