Thanks for the recommendation!

Hi Elizabeth. The enzymatic cleaner won’t have an effect on the efflorescence. A mild etching solution will usually remove it. There are also efflorescence removers available. I would recommend performing that after you have completed your enzymatic cleaning to your satisfaction.

I have white stains in the areas I’m treating, and noticed they become more prominent after treating with the TSP / rinse / vac. I initially thought these were the stains that the TSP was expected to remove, but after some googling I believe it is actually efflorvescence. (This is a concrete garage floor, for reference.). Will the enzymatic step help to remove the white buildup, or is there something else I should include in my process? Thank you!

Hi Carolyn. You would need a minimum of 3 gallons for that amount of square footage, not counting the walls. Assuming the walls are concrete or block, I’m not sure how high you need to apply it. The bigger issue, however, is the paint. In order for proper bio cleaners and enzymatic odor removers to work, they need to come in direct contact with the concrete. The paint will effectively block them from penetrating into the concrete to do their job. The paint will need to be removed before you begin. Grinding is the best method to remove paint from concrete. We have an article here that explains how it works.

Hi Miss Rebecca. The treatment won’t work on concrete that has already been sealed. The job of a sealer is to block liquids from penetrating or slow them down from penetrating very fast so that they will hopefully evaporate first. This allows time for them to get cleaned up. What type of sealer was used?
