Silicone discolouration

[Charlie57]

I've noticed that where the cab meets the motorhome body the small gap is filled with silicone which even on new models get discolored and/or mouldy is there a way to keep it looking white?
Thanks in advance

It is not silicone that is used, it is a polyurethane adhesive, similar to sikaflex. If it eventually starts discolouring, products like traffic film remover used neat, but carefully will bleach it back to white. Some body joints, the converters use a non setting mastic that gets very dirty. Easily cleaned with white spirit though

OK I'll give it a try, thanks.
