We have been cleaning the carpets at a pre cast concrete plant for about a year and a half now about 6 month intervals. We actually also do the janitorial as well and could actually glean wisdom from potential answers or speculations from this thread. Here's the most recent finding. I researched cement components and found out that fresh cement comes out around 13 or 14ph! Considering the carpets are packed full of this dust what are some theories you guys might have on how this could affect how the carpet is clean?
