Orange staining on basement floor and walls

mcervinojr | Posted in General Questions on

Hey guys, Mike here.  I recently just refinished portion of my basement.  I noticed however in my unfinished storage area a small orange color dried puddle on the floor.  It also appears on some of the walls that were painted w/ Drylok a few years ago.  I never really notice water or leaks, so I’m not sure if this was an isolated incident.  All noticeable cracks were sealed w/ hydraulic cement in the finished area before the rigid insulation was installed.

Advice would be greatly appreciated.

    I would guess that’s iron staining, but I can’t tell for sure from your pic. There is a product called “iron out” that’s usually used to clean water softeners, but it also works well mixed in a water solution and used as a cleaner on concrete. You could also try “lime away” and “CLR”, both of which you can buy in spray bottles in stores. How well each cleaner works will depend on the chemical nature of the actual stain you have.

    Make sure you are wearing good rubber cloves while you’re working on cleaning this up. None of these cleaners are things you want to have on your skin for any period of time.
