A cheap bottle I had containing benzalkonium chloride, for household cleaning, leaked entirely into one spot on my basement floor. The leakage wasn't noticed until after my carpet was bleached orange and the benzalkonium chloride solution was already dry. The carpet and padding have both been replaced since then; however, the fumes emanating throughout my basement have not gone away! Do I need to peel-up the padding and scrub the concrete surface using a special surfactant? I have no clue about how porous basement concrete can be, but maybe the liquid penetrated deep into the concrete material.
How bad can this be? All thoughts and advice will be greatly appreciated. Please offer any insight you can. Thank you.
