Thank you for sharing. Going to do this on some areas of new concrete that have this issue.

the bricks were still not dry when you showed us your results . it takes a couple days for them to evaporate the water all out completely dry and youll be lucky if the salt drys out before it hits the surface.

after all this time, when the bricks fully dehydrated did the salty bricks not want to be nice and cooperate by pushing out the salt the other direction? meaning did salt resurface?

happened to me on a brick house built during ww2. after battling with several different methods i finally tried to just let the bricks push out all the salt out first by wetting it repeatedly and letting it absorb the water then i used a torch and hair blower to dry the bricks one by one . then i used various wire brushes and angle grinder with wire wheels to remove the salt as much as i could and i used a steam vacuum brush with no water but only hydrochloric acid being sprayed from a bottle . all i can say is these bricks were very salty for what i was doing to them . .. after days of working on it little by little with full patience i managed to remove most of the salt . i knew this because they would not get any more white after i used hot air to quickly dry them.

well after this i ended up getting hold of a sand blaster and blasting off the top layer i was left with .. only after fully letting the bricks dry for over a month though.. by the way i blasted baking soda mixed sand and with no water.

im pretty sure there is still alot of salt in these bricks no doubt, but i wonder if i would of used the blaster from the start without saturating the bricks with any liquid, would they have left me with the same results that i have now.. which is looking about 3 shades from new..
i learned that any liquid will bring out the salt after it dries no matter what unless you get the salt to dry before it hits the surface..
also when you build a house from brick always waterproof seal the brick immediately

People are sure bashing about adding water to acid, like they didn't read the comments. It looks like the jug says it makes 5 gallons, which would mean that you would use 4 parts water to 1 part acid. Looks like it still did ok at 5 to 1though 🙂

Now you have to go one step further. You will seal it with an impregnator from drytreat, specifically StainProof- salts cannot make it through

What to do if without that solution? It is not available in our country.

Will the run off cause my grass to die??

Can this be done in bathroom tiles too? I mean this chemical?

Where can I get this product online and what's the price?

You added water to acid, that is a no no, it can cause a reaction, always add acid to water.

Great video, but I'm cringing about pouring water in to acid!!

Just to make it clear: Vinegar is an acid, just a weak one.

Please, oh please, never add water to acid. It can explode. Always add acid to water. This was a horrible example of safety. I’ve seen it happen. The results of acid on the skin is not pleasant! Please do not follow this poor example of how to mix an acid with water! Another thing to consider is wearing a respirator rated for chemical gases if working in an enclosed area.

ALWAYS ADD CHEMICAL TO WATER. NEVER water to chemical.
