Talk Morgan Forums Morgan Sports Cars Maintenance & Servicing Engine Cleaner Recommendation

What recommendation does anyone have for cleaning engine and engine bay? In the past I've used Gunk but I don't really know why I chose that brand - probably because that's what they had in Halfords. I remember the Gunk process as being rather messy and wasteful though because it's a very liquid formula that splashes, drips and runs all over the place without having a chance to do any work. Are they foaming or gel alternatives now? Are they any good?

Thanks in advance
