I'm in the process of working on my garage including filling in some
cracks running through the garage floor.
My plan is to use self leveling cement to fill in the cracks and make
the floor level.
I'm looking for an alternative to muriatic acid to clean up the garage
floor and provide a stronger bond between the garage floor and self
Muriatic acid is hydrochloric acid (HCl). It etches and cleans the cement
you currently have. It is (or at least should be) easily rinsed off.
Moreover, since HCl is a gas, it should really totally vanish when the
floor is dry, aided easily with some ventilation. Doesn't your garage have
a big door?
The acid is to etch the concrete. If the concrete is "dirty" with oil
or paint, these will shield the concrete from the acid.
Clean the concrete first with a "cleaner" appropriate to the "dirt"
and etch only if suggested by product you plan to use.
I use powdered laundry detergent (Tide) to remove oily dirt, paint
remover or mechanical means for paint.
I acid etch for epoxy paint.
The product (or mfr of the product) you plan to use for leveling will
provide (or should) prep instructions.
If you have a clean concrete there are bonding agents that can be added
to concrete to aid in bonding to a previous surface. May or may not be
appropriate for the self leveling cement you want to use.
Ask the self leveling cement manufacturer for suggestions?

I've used both. Phosphoric works, but not nearly as agressive as
hydrochloric or sulfuric. And the cleanup us more work. Mabee the
Phosphoric I used wasn't as strong as the hydrochloric and sulphuric
were. The big advantage to the sulphuric is the acid was free and we
needed to get rid of it one way or other anyway. A big pile of
batteries that needed to be shipped to the lead smelter netted in
excess of 10 gallons of pretty strong acid.
The advantage of hydrochloric (muriatic) is it is available from any
pool supply or hardware stoor.
Phosphoric hardly fizzes at all on normal concrete, while Hydrochloric
and sulphuric really "get up a head of steam".
The phosphoric is definitely SAFER.

There is a salvage yard in ND that recycled batteries with the sulfuric
acid dumped. They had to excavate a lot of dirt and send it to a haz
