We finished cleaning the windows on a large house today and noticed the walkway from driveway to front door was really loaded with algae and moss. I was going to mention we also clean concrete but this just didn’t look like it would stand up to pressure washing.
How do you all clean such neglected, cracked walkways?
A pic would help us give you better feedback
Sorry, didn’t get a chance to. I’ll try to find a similar pic online.
Sorry if this isn’t allowed, but if you scroll down the page a bit you’ll see a similar walkway. Not sure how to post pics on here.
3-4% SH pre treatment
Trust your gut. You said it didn’t look like it could stand up to washing.
So use chems to clean it and low pressure to rinse it. Problem solved
