This is effective! It's chemical PLUS abrasive since he's in there scrubbing it around. But I think the OP meant the thread more if this CRC cleaner was good by itself (AKA, just spraying it in and letting it do it's thing). At that I say no. Using in IN CONJUNCTION with abrasives (like this video you're sharing) is certainly the way to go if one does not have access to REASONABLY PRICED walnut blasting.
