After nearly three seasons of very regular use, my swim goggles finally gave out. I actually purchased a 3-pack of these goggles before I joined TFP. The first pair did not last the full season. About the time I began using the second pair, I learned about TFP and switched to the TFPC method. Same goggles-same make-same package. The second pair lasted 3 times longer and the only thing that changed is how I manage the pool. I'm also finding that swim suits are lasting longer.
Now, what was that about bleach being harsh compared to other forms of chlorine?
