Hello! I recently had to switch out my dip tube that was in sitting in a new brew with another dip tube that had been sitting in a separate keg. This other keg had some mold at the bottom of it but it was not touching the dip tube. I ran pbw and star San through the dip tube and scrubbed the outside of it before putting it in the keg that had the new brew. I had to do this because the one I had to take out was clogged. My worry is since I had no scrub that I could use to clean out the inside of the dip tube that there could be residual mold inside of it. Could it ruin my new batch of beer? Or make me sick? This batch is nearly done carbonating and everything looked good while transferring to the keg. I am just worried that I had maybe introduced mold to it.
