How do I remove a slight case of mold from the cement block of my unfinished basement? I have some growth by the washer. I read that bleach does not get in the pores of the block and the mold will come back.

Get some Jomax solution and follow the directions. HD should carry it, if they don't a good paint store will have it.
Found this via Home Depot:

Afterward, make sure you prevent it from coming back by managing the humidity.
I like this. And then dehumidifiers.

No braineer. Peroxide. Never use bleach again. You can use it straight from the bottle (3%) I usually use a 50/50 peroxide/water solution.se it on my base3ment block.
You can get a big bottle from walmart for 88 cents. I always keep it around.

Muriatic Acid 1 gallon to 5 gallons of water.
Brick Mason for 20+ years.
They most likely didnt water proof your basement. You will have to seal coat the block. Preferably outside of it or will continue to come back.

I am sure you are correct. But I still would avoid breathing Muriatic fumes (breath oxygen from the peroxide instead). And as you said the only sure way to stop it in the future is to seal the outside.
But if you have no major problems other than this the peroxide will get rid of the mold. It will have to be retreated periodically.
Aside: There are 2 things I will never do in life anymore: Use bleach (peroxide instead) and get frustrated buying ammunition at Walmart (thanks to Bubbatime)
