I am using Muriatic acid which will go into the ground from cleaning a
garage and wonder what hardware or grocery store product I can mix
with water to neutralise run off. Would Baking Soda work?


Soda Ash and water.


Yep. AKA sodium carbonate, available in 5, 10, and 50 lb sizes
at pool supply co. Call around for local price.





While baking soda will neutralize the acid that runs off into the soil, more
than likely soil itself and the concrete you cleaned with it (assumption)
can do the job just as well. Most of the chlorine comes off as gas and some
gets converted into salts. In the long term its safe but in the short term
it will kill bugs and grass

For what gets soaked into the concrete, use ammonia after it dries and you
wash it first. Do this especially if you plan to seal it particularly
acrylic surface sealer (as opposed to a penetrating sealer).

Muriatic is not the best for concrete, it will etch quite well but the fumes
are bad and it can penetrate leaving oily looking spots which defy cleaning
with just water and soap (hence my comment about sealers). I have to admit
it is far cheaper and generally more aggressive than other products so in
general a good choice.




We used muriatic to etch concrete prior to sealing. Just washed off
with plain water, as, I'm sure,
the instructions said we should. This was 2nd floor deck, with concrete
walks, plants, and structural
walls near. No effect on surrounding area. Dilute acid will probably
help the lawn )
