We use a product called "pink" on our heavy plant and hgv's it's made by chrome northwest. They have a full range of cleaners, polish, rubber care , tyre dressing and detailers/dressers .
Pink is a dressers which is a bit greasy if you use too much but it's very good , can be used on all surfaces. We have used it many times on many different things ranging from a hgv's to my front door. I can also recommend the tyre shine .
It was recently recommended to me by a local firm that enter their hgv's into shows and it's the best thing on the market according to them .
I have no connection with the company apart from using their products.
