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.
These and other surgical meshes may be used not only in hernia repair but also for Pelvic Organ Prolapse and Stress Urinary Incontinence. Regarding these kinds of products in general, FDA has issued a Public Health Notification on October 20 2008.
