I bought some play-sand for our new sandbox on a rainy day, then left the bags unopened on our patio to dry for a few days.
It's been about a week and they haven't dried, and now my wife is wondering if they're growing dangerous mold/bacteria/what-have-you and should be discarded.
So, my questions:
- Is this fear justified? Should we get new sand or treat the sand we have somehow?
- Are wet bags of wet play-sand actually common and we should just dry them out going forward?
- Is the sand likely to dry adequately by leaving it in a sandbox for another week with its cover on?
