I am not sure if Shield products are available over there (I am based in South Africa) but if so, I use their heavy duty vinyl and rubber cleaner and it works an absolute treat.
I simply squirt a little on a MF towel and wipe clean.
I am sure there must be locally available products that work the same?
However, prevention is always better than cure, so ensure you tape off the areas you do not want to get splatter on in the first place, and this will mitigate how much cleaning, if any, you need to do.
I then always dress/treat the rubbers with a UV blocking type dressing to restore the nice original black look and provide some protection against fading/cracking etc.
