I have had issues with Oxyclean. There are plenty of people have never had any issues with the product.
PBW is supposed to be so expensive. I like to save p a few bucks as much as anybody else. However, I am a right tool for the job kind guy. At some point aggravation cones at a cost as well. So I did the math, using PBW costs me an extra dollar per brew day.
If you want the best of both worlds, there are threads about mixing up your own PBW. One major ingredient is Oxyclean. I have read them, I still buy PBW. It is what I know and trust. But I am just one opinion.
