We salvaged some pavers from a demolition site, to make a small area for a picnic table, and have some mason sand left over from an addition that we built over the past couple of years. I know that this is not the right sand for this application, but rather than leaving it in a covered pile indefinitely, or burying it, are there any reasons that it won't work under the pavers? No vehicle traffic in this area of the yard. Thank you.
I would say that the sand you ahve is okay provided it is not so fine it resembles mud when wet.
When cleaning anything including baby diapers, it is better to sweep off or scrape off as much solid and semisolid material as you can first. (1) Less cleaning fluid or detergent needs to be used, (2) Less of a mushy mess which in turn means that bleaches or disinfectants will be more effective.
