Painless Splinter removal - 1/4 tsp of baking soda and enough water to make a paste put on a splinter will force the splinter out on its own. If Splinter is shallow there is no need for tweezers. Place paste on the splinter, let sit until splinter is mostly out of the skin then wash away with soap and water. Can take between 20 mins to 2 hours depending on how deep the splinter is embedded. Deeply embedded may need tweezers, but it will be easier to get it out after this.
