Mr Muscle for gelcoat cleaning

The man I bought my boat from 14 years ago used to clean her gelcoat with Cif (Jif?) during the 8 years he owned her.

As she is now 44 years old, still unpainted and polishes up well it can't have done any harm.

I also used Cif for a couple of years but I now clean off the yellow stains with Y10 once a year and I pay someone to machine polish her. He uses some kind of automotive cleaner (that I can't remember the name of) and then waxes her.
 
Do any of these remove the UV fogging from well maintained newish gelcoat, or is a mild gelcoat restorer the only way to get the shine back? or are there any short cuts?
 
A creme cleaner works well. They are usually a very mild polishing compound that cuts through the years of grime on a gelcoat and removed any chalked surface.

Cheap and effective. Polish with a good quality polish afterwards.
 
Cheap dishwasher powder a bucket and soft brush. Decks get the same treatment but with a stiffer brush. Polish sides etc. with Autoglym Super Resin polish.
 
I have used EVM and was very happy with it.

I'm new to this boat owning lark and went in to Jones in St. Ives to get something to remove copius amounts of bird mess off the roof of our Seamaster. No hard sell, no pushing me towards the expensive high-tech products, the chap there recommended EVM ("not as agressive as some of the other cleaners, might need a second go") and I'm very happy with it's performance. Particularly impressive was the way it lifted years of grime and stains from the corner fenders.

Safe to rinse off into the river too.

Gets my vote.
