Pretty sure it will also make short work of the zinc.

Muriatic acid, with gloves, using a rag.  It will make very short work of the Portland cement

some baking soda on tha area to see if it’s been sufficiently neutralized )

Try a wire brush, then touch up any damage to the galvanizing with
cold galvanizing compound. Rustoleum and many others sell it in
a spray can.

Hi Mates,

We made a huge error and poured the concrete for the base of LM 354 HD
without covering the galvanized legs and then did not clean it of concrete
immediately.

Now the concrete got stuck really well. We tried a pressure washer. It does
not produce a good result.

Any advice on what can be used for cleaning legs without damaging the
galvanization?

Thanks,

Alex, WK1O
