Any idea what is in antibacterial handwash that could cause permanent staining.
Been to a job where kids had thrown a full bottle down stairs, literally looked like a full red/pink tin of paint had been spilt, every single step covered.
I couldn't remove it or even improve it, to be honest i wouldnt have attempted it if it wasnt a repeat customer.
Still dissapointed though...
Is there anything added that could cause permanent staining? It was bright red
