Instructions
Empty the sandbox sand onto the plastic tarp with the shovel. Inspect the sand for insects or anything else that may look questionable. If the sand is infested, throw it away, if not, spread it out and hose it down with the water hose.
Rinse out the inside of your sandbox with the water hose. Wash the inside of the sandbox with the all-purpose cleaner. Rinse and then rewash with the dish soap. Rinse again. If your sandbox is bottomless, skip this step.
Line the bottom of your bottomless sandbox with the plastic liner or landscaping fabric. If you are using a plastic liner, be sure to poke a few holes in the bottom for drainage. If your sandbox has a bottom, skip this step.
Put the washed sand back into the sandbox. If your sand was infested and you had to throw it out, purchase new play sand.
Cover your sandbox with the plastic tarp or the cover that came with the sandbox. Make sure the cover is securely on the sandbox to keep out insects, birds and cats.
