Now, I use Aurora Speed Clean for my Achilles Dinghy.  My dinghy was in need of a real good cleaning and Aurora Speed Clean did the job with very little elbow grease.
Last year I officiated my niece’s wedding in Boston.  While I was walking around the Boston Harbor Wharf I met a guy who was cleaning the worst looking dinghy I had ever seen (perfect timing) and it was coming out looking like new.  
I asked what he was using and he handed me a bottle of Aurora.  There was about 1/3 left in the bottle, he said take it and try it.  
This stuff works.
