Questions & Answers

Is this a concentrate? If not, how much surface will a gallon cover?
For advanced biological growth it is recommended to use the D/2 undiluted.
Typical coverage is 250-350 square feet per gallon. -
We have numerous old limestone headstones from the mid 1800s to modern ones in our family cemetery - some 300 total. I'm wondering just how much cleaner it would take to clean all of them. They were professionally done about 15 years ago so there's not a lot of 'buildup' on them. But we're worried about the cost.
Typical coverage to remove medium stains will vary from 250 to 350 square feet per gallon. This can vary depending on the porosity of the stone.
I would estimate you would be able to clean about 25-30 of these headstones per gallon, therefore about 10 gallons total for 300. -
