Epoxy resin can be a messy substance. As a result, spills and messes are likely to occur. The most important thing you need to remember when cleaning up a resin spill is that resin and epoxy should never go down your drain. If your resin spills, you will want to clean up the mess as soon as possible. Once the substance cures, it will become more difficult to work with. It's recommended to wear a pair of gloves to protect your skin from the product.  You will need a firm object. A butter knife or a similar item will do. Use the item to scrape off any resin you can from the surface. Once you clean off the majority of your resin, you will need a towel.  Dampen the towel in a solvent (such as acetone)and thoroughly clean the surface where the spill happened.  Once the solvent dries, you can recheck the surface to see if you missed any resin. Any remaining resin will most likely cure by the time the solvent dries. Removing hard resin will require scraping with sandpaper or a similar tool.
