I mix my own all the time, blending acid crystals with a pinch of a neutral cleaner. It takes experimenting but will save a pile of money in materials costs. I spent a lot of time in Hawaii and always hated paying for all that shipping cost for something that is 95% water. Sulfamic and for more rust oxidized materials oxalic, and then a small amount of hydrochloric, 5% if necessary.

The best bet may be to follow John Freitag’s lead, however, I have found Sulfamic Acid a great substitute for any products that carry the harsher solutions like hydrochloric acid (muriatic acid).
Advantage: Sulfamic Acid has little respiratory or contact danger and can be purchased as a raw material at most chemical supply facilities. It cost about $1.00 / lb. Probably need to purchase 50 lbs.
Dissadvantage: You are assuming the risk of being your own chemist without the support of a product manufacturer.
John,

Instead of using Muriatic acid I would prefer you to use a masonry cleaner from SureClean this product work well at removing efflorescent.

I used your suggestion Mike and it worked great! I had to go stronger with the muriatic, let it sit about 15 min and a strato grit brush with 200 lbs of weight worked great.
Thank you!

Use the brush with the acid, about 10% and some oxalic, a touch of neutral cleaner for a surfactant, that’s what I do and it works great.

Thanks mike. I had previously tried a nylo grit with no results. Straight hydrochloric acid seemed to loosen it some. Maybe I could try the strata after allowing hitting it with acid.

Use a strata grit brush (80 grit) and if you need a smoother finish follow with a nylo grit (120).

Any quick input on this one would be greatly appreciated....
I have an old lobby slate floor, 1000SF, and successfully removed ugly epoxy coating. When dry, on only certain tiles(20%), there is heavy efflorescence that I have not come across. It is mineral buildup that is very hard.(it barely scratches with a screwdriver) Acid cleaners did not make much of a difference. Grinding the floor would be too much work because of its rough texture, and it would end up flat.
How can I get rid of the buildup? I am thinking of trying a stronger acid, like muratic acid. The only solution I can come up with is possibly antique brushes on a variable grinder? I have no idea how that would work. Shot Blasting with baking soda, but that would be a pain...
Thanks!
Jason
