Which dish soap works better on cold, congealed bacon grease — Palmolive or Dawn?

Palmolive cuts through three-day-old bacon grease without hot water — just cold tap water and a reasonable amount of soap. Dawn also fights grease well, but it needs hot water to really dominate. If you deal with grease that congeals like candle wax, Palmolive Ultra Strength works under conditions Dawn finds challenging.
