What can I use to scrub my patio concrete floor from stains

utilise du break wash: vaporise du break wash sur les taches, laisse le travailler 3 minutes et frotte avec une brosse d'acier de mécanicien après rincer a grande eau. P.S. fait une tache a la fois.

What ever you do it may not all come off or out - If all else fails consider Painting with a Concrete Stain.

TSP (trisodium phosphate) applied with a push broom.

Try using Simple Green and a scrub brush. It does well on concrete and is biodegradable.

Hope that helps

Yes, TSP works well. It's a degreaser. If it's really stained, the pro's use a pressure washer. They can be rented at Home Depot or other rental places.

Muric acid but be very careful ,

TSP from a home store and a brosh floor cleaner would be best bet.

I use "Wet-N-Forget". Available at most hardware stores. Mix it with 4 or 5 to one (one part product and 4 or 5 parts water) pour it on the concrete (scrub if badly soiled) and concrete must be dry before applying. Then just forget about it. The wind, rain and sun will activate the product.

Yes use a pressure washer and a really good degreaser of some type or the "wet-it-&-forget-it". The lady mentions above.

Inused CLR on mine and it cleaned most of the stains. Lemon juice is supposed to be great but I haven't tri s it yet.
