Does anyone have information on what the base chemicals are in products such as Eaco Chem’s Heritage Restorer and SESW Monu-Mental?
I have a job coming up (pic below) which is natural stone (sandstone I think) and I have heard that SH can degrade natural stone due to the salts it leaves behind.
I’m located in Australia so the above commercial products aren’t available. Would a benzalkonium chloride solution work in lieu of said chems?
I’m surprised nobody has replied yet. I’m no expert so take this for what it’s worth, pretty much every site I could find on the subject suggests chlorine bleach that we all know and love. I’ve certainly used it on limestone to good effect, just potentially need to neutralize with oxalic.
