Will Bleach / Water mix harm old brick foundation?

I have a few spots of mold on the interior of the foundation wall that I would like to clean away with a bleach / water mixture.

The foundation is older brick (red brick) and it is in good shape but I don't want to harm it. Will chlorine bleach harm the mortar or brick face? The foundation is about 70 years old, and is in about a %40-50 humidity environment.

The mold is from condensation I am sure as I have never seen water leaking from outside and drainage around the house is good. I would like to clear up that light moldy smell.

thanks
Fin

Should be fine! Make sure you dry it within 24 hours or the mold could come back.

to add, do not use straight bleach. Best mixture is 10:1-water bleach.
