Silicone Hoses

[Graham-P]

Does any one know how to clean up the silicone hoses? They have gone a dirty dark blue colour.

I'd start by trying a strong solution of APC (all purpose cleaner). I favour the Chemical Guys one, but Meguiars do a similar one too.

They do get stained sometimes, and I reckon the only cure is replacement.
