what engine cleaning products do you use?

[Dead Eye]

Oddly the best product I've used is probably the Muc-off chain cleaner... I'm sure their other products are probably as good but the chain cleaner is the only one I've bought. If they have a specialised de-greaser I'd hate to think how strong it is haha

I've used Ultra Gunk in the past, but it wasn't really that great for caked on stuff. Cleaned the ally wheels on my car pretty damn well, but wouldn't used it for the front of the bike engine
