When the sealant around the doors , water point covers, battery boxes etc, get grubby due to road travel, or maybe rain downfall on seasonal vans, what do you find is the best, to get rid of it. ?

You need to be careful as some sealant cleaners may affect the aluminium. I use Silky on the plastic bits and sealants. A very soft toothbrush might help but don;t use a cheap one as the bristles might scratch the paint. (They also scratch your teeth and gums!!!!!!!)
