We are about to install our recycled glass countertops. They are made of resin (NOT concrete) and recycled glass. GlassRecycled.com recommends a pH neutral cleaner such as Simple Green. EWG doesn't rate Simple Green very highly in terms of Eco-friendliness. I have always used 7th Generation, but I emailed them and their pH is 10, far from pH neutral. Suggestions?
Hope this is the best forum to post this question.
