Sand dollars can be used to make beautiful decorations and crafts, but first, they need to be hardened so they don’t break. Hardening sand dollars is a fast and simple process that anyone can do with a few basic supplies. Preparing your sand dollars with bleach and water and using glue to harden them will ensure they turn out white and durable when you’re finished with them.

Things You Should Know

  • Soak your sand dollars in water then clean them with a 1:1 mixture of bleach and water. Let the sand dollars dry completely.
  • Mix together equal parts white glue and water. Use a clean sponge or paintbrush to thinly cover the entire surface of each one.
  • Place the sand dollars on wax paper or a baking rack to dry until they’re no longer wet or sticky to the touch. Then, use them for displays or crafting.

  3. Take the sand dollars out of the water and bleach solution and rinse them with fresh water. Gently scrub each sand dollar with a clean toothbrush. [2]
    • If you don’t successfully rinse off all the bleach, your sand dollars may end up with a yellowish tint.
    • If your sand dollars are still discolored or dirty, soak them in the bleach mixture again for 1 minute and repeat until you’re happy with how they look.
  4. Lay them out in a single layer on a wax sheet or a baking rack. Check back in an hour to see if they’re dry, or let them sit overnight.

  3. Lay down chopsticks, toothpicks, pencils, or inverted thumbtacks on the wax sheet to slightly elevate the sand dollars so the bottoms dry faster.
    • Let the sand dollars sit until they are no longer shiny, tacky, or wet to the touch.

    How do I bleach sand dollars?
    Community Answer
    Add a little bleach to the water when you wash the sand dollars, or you can set them out in the sun. Use a tiny bit of bleach in soapy water when you clean them to kill any bacteria so they don't smell.
  • Question
    How do I dry them? Doesn't the wet glue adhere them to the drying surface?
    Community Answer
    Let them rest where there is sunshine for about a week. They will naturally dry out.
  • Question
    Does bleach have to be used to harden my sand dollar?
    Community Answer
    No, bleach does not make them hard--the bleach is to make them white, and actually makes them more brittle.
