How do you clean stained concrete floors?
We have stained concrete floors in the office that I work in. I usually mop them first with water...(if they are really dirty). Then I use Mop and Glo for Teflon...it really seems to shine them up. Another trick you can try between mopping is get a dust mop and spray it with endust and go over your floors...DO NOT SPRAY ENDUST DIRECTLY ON FLOOR----it will make them slippery. If you just spray it on the dust mop and than go over your floors it will shine them nicely.
Muric acid availible at your local lowe's or home depot . It's sold to just clean concrete floors before painting or epoxy coverings.
I doubt if you can. Cover it with latex or paint. Or, maybe best of all- put 2 inches of concrete on top and hire a machine to polish it nicely.
There's a special cleaner you can get for it. Look at the hardware store.
muratic acid (hydrochloric acid at 32% strength) is available at home improvement stores. just be careful.
