There are a few things you can do to clean white checkered vans. The first is to use a mild soap and water solution to clean the van. This will remove any dirt, dust, and other debris that may have built up on the surface of the van. Next, use a vacuum cleaner to clean the inside of the van. This will remove any dirt, dust, and other debris that may have built up on the interior of the van. Finally, use a hairdryer to dry off the inside of the van. This will remove any moisture that may have been present in the van before it was cleaned.
