Some states have banned the sale of TSP because they fear that phosphate from its rinse water will cause environmental problems in waterways. Amazon carries TSP and will ship it to you if your state allows it. Don’t bother with the phosphate-free version. If you choose OdoBan, use the original OdoBan Concentrate. It’s hospital-grade and will kill bacteria from pet urine.

Would Odorban Rinsfree be ok to use for cleaning the sealed concrete first? Or is there another cleaner you recommend? TSP seems hard to find. Thank you for your help.

Hi Jason. I would clean the sealed surface first and then apply Rocco & Roxie. Make sure you give it time to work. Shellac or other coatings will not adhere to sealed concrete and will peel. The surface would need to be prepped by grinding to remove the sealant.

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.
