I have been using the Alkaline Brewery Wash at Denny's recommendation and it works really well. I run it thru my homemade bucket/keg washer and it seems to pull all the crap off. It takes a bit of scrubbing to rinse it off though, but all in all, it is a good product. But, with that said, it is a bit pricey. I am thinking of trying the Oxyclean Free. I can get double the amount for half the price and I am guessing as long as I practice good procedure it should be ok. Gonna give it a try and see which works best. Either way, there are plenty of products out there and even a do it yourself recipe. I am just not smart enough to figure out the measurements on it. LOL. Either way, Rock On!!!!!
