Can you use castile soap for cleaning your equipment? It's basically a mix of olive oil and sodium hydroxide, but I've never known anyone who said it was, or wasn't, an alternative for other cleaning agents prior to sanitization.
Same with Yoop, if I need to clean anything I use Oxyclean or if I have some PBW (but that's rare) and hot water. But mostly I just use hot water and a something to produce pressure, like a carboy cleaner or a garden hose pressure wand.
