where can you get it in calgary? or anyone have a jug I could borrow this weekend?

 

I think most building supply outfits carry it. I think it is used for etching concrete.

 

Canadian Tire,Home depot or Roma...Thats where I get it..I'm out also...I got to get some also

 

What did you melt?

 

nothing I need to douche the driveway of a few oil scars.

 

Let me know how that works. Looks like there was a murder on my parents driveway from the dually.

 

Following with interest. Before after pics would be great.

 

This stuff works great on scaled up toilets...But you have to wear a chemical mask...because as I remember,water and muratic acid creates hydrogen chloride gas ...And thats not good...

 

as far as I can tell, muriatic acid is the shelf name for hydrochloric acid. its slightly browned the concrete where its touched. but I'm not sure if thats because I got a bad batch of conrete to start with of a bad install on the driveway. so. Im not worried about it. it may treat old seasoned conrete different.

but yes it did wipe away most all the spots. with a short soak in diluted acid and washed with the pressure washer. took the black as night spots to light shadows at best.

 

Oh and I got it at Home Hardware, homo depot won't touch the stuff. its in plastic jugs that are sealed in plastic.

 

muriatic is a 31% solution of acid.......... the fumes will bug the heck out of ya, head high and face to the fresh breeze.

 

Want to know another little secret about Muriatic Acid?

You can use it to bring the PH level down in your hot tub if it's to high. And yes I do use it for that purpose. It works way faster than using the PH lowering crystals

We used to use This TRISODIUM PHOSPHATE for cleaning And prepping based Before we coated Cement The Retail brand of this is the Shell Busey stuff From Home Depot

 

TSP is a non sudsing detergent, works great mixed with warm water and bleach to make treated wood look like new. Removes mold etc. Also for cleaning walls before painting, etc. Good stuff.

 

I tryed the TSP on my driveway 1st. $9 for that jug figgured why not. well it didn't even touch the oil stains.
