What is the best way to clean black mold from white decorative porous blocks. Can you hit it with SH and wash with a power sprayer, or is there a more preferred method of cleaning this block. The roof is a light color and after it is cleaned the block will definitely be an eye sore

I would hit it either with SH or OneRestore by eachochem. SH is cheaper, try that 1st. rinse with necessary pressure to remove residual.

some blocks have Iron ore in them and they will rust when hit with sh.. do a test area.

Do you need pressure to wash off Sh or will hose pressure work to rinse
