I wasn't told at my local store that Pendulum could stain concrete. After apply There is some over spray which wasn't able to be washed off. How can I clean the concrete?
Normally, you want to try to rinse the area immediatly after over spray. The manufacturer says that muratic acid(found at many janitorial supply stores) will help to the yellow stain left from Pendulum 3.3 EC.
