I use a Discwasher and had run out of my giant (6 fl oz) D4 that I bought decades ago. I gave this product a try and it works great! I like that it comes in a large bottle. Not only does it clean it appears to SHINE the records a bit--I like that. Recommendation--if you have a small bottle of record cleaner (like my 1.25 fl oz D4 liquid I have) keep it and use it as your record-side cleaner bottle.
