Dear Harlan, List;
One can dilute acids with baking soda. Always wear eye protection and
glasses, and do it in a well ventilated space, or better yet, out of doors.
One of my favorite environmental phrases is "the solution to polution is
dilution" which in this case....well, my muratic acid for cleaning the
calache off my petrified wood, etc, is encouraged by the local city
admin. guy as it helps clean the nasty alkaline deposits off the sewer
pipes. Our water, as is most water in the western US has hard stuff in
it that gets disolved by a little acid now and then.
dilute the water with acid, and add baking soda, done deal. Check with
a ph strip, and flush.
