I have a handrail that runs the length of Our steps that i will remove surface rust prime and paint. I dont want to kill the blue rug juniper on either side and of course we somestimes walk barefoot.

soda i hear is bad for plants.

not sure of impact of al oxide, crushed glass , sand, slag , and so on.

will the glass beads leave minute piece of glass every where.

also, i will be blasting small sections at a time and would rather just sweep up what i can.
thanks
