    Quick question here, have any of you ever cleaned mold off cinder blocks in the basement? I was wondering if you should see nothing once it is clean.

    I have read to use Borax, and have used it, but I still see black on the cinder block. So just wondering, should I still see black on the cinder block?

    Finished or unfinished?

    Power washers work wonders, but if finished its a no go obviously.

    Borax, bleach, etc otherwise

    Due to them being porous, it will be a PIA

    Like 3.8TransAM said, cinder block is very porous and it will be a huge pain. Two things that mold needs to live is water and stagnant air. If you can eliminate one, then your mold is done for. Use the bleach method. After that ensure no more water can get to it and keep the area well ventilated. Of course if it is a foundation, then good luck, they never should have used them in that application and nothing will help short of a proper moisture barrier and weeping tile system.

    Can't say I know about the diffusion properties of bedliner products. If this is any form of foundation though (which I suspect), it will have to be sealed from the exterior, which is a huge can of worms to open. Also if your going to do that, It would be best to use the products that are specifically meant for this application.

    Bleach actually kills the mould then I use tsp (trisodium phosphate) to clean it up.

    Bleach is definitely your friend in this situation. A pressure washer afterwards might help as well. I've had mixed results with TSP.

    I've hosed it down with bleach - like, saturate the shit out of it - I used a sprayer that I used for bug spray, one of those pump ones. I put a fan up to dry the wall afterwards.

    Are you going to paint the blocks? Because if so, you can kill the mold, let the blocks dry, and then go over the blocks with Kilz primer - it's at Home Depot, in the paint dept. This stuff smells terrible, use a mask or vent the room, but it'll fill gaps and no mold oughta grow on it.
