Limestone siding cleaning help needed
I'm new to the forum, so...
What methods/products do you use to clean limestone sided houses?
As a homeowner (not prowasher) I've tried a couple of commercially available house washes, used them as directed and was disappointed with the results.
I went back to my tried and trusted SH mix, along with general power washing and was please with the results. The true soft wash method removed very little green and black mold, it took power washing to get most of it out. I would say that with all the rain we've had in Central Texas this year, the black mold is deep in the porous limestone.
Do you know of any other method or product to remove the deep black mold?
Also, since limestone is so porous and with the current heat we're experiencing, I'm having a hard time keeping the stone whetted while working, the SH and soap mix I use seems to soak in within seconds. Would a commercially available surfacant work better than common dish soap for this application?
Thank you for your time, Bill, Austin, TX
