The top of this photo was treated with 1c/gal,
The bottom of this photo was treated with 1/2c/gal.
Reckon I’ll be goin’ with a full cup henceforth!
Question: is oxalic OK on 1)steel lamp posts, 2)vinyl siding, and 3)galvanized steel?

Really appreciate the tip to both brush out the oxalic and keep it wet for best results from squidskc. I am not finished with that sidewalk, but will wait until after the rain to retreat it.
