In addition for your information:-
Universal is an extremely versatile cleaner (not polish) for all soft and hard surfaces (for exterior work only required for localised cleaning where stubborn substances such as brake dust, ingrained bird lime, tree sap, engine grease). But as discussed on commercial vehicles such as vans, etc.. the finish is certainly one that is clean and revitalised, therefore may be a consideration for you due to dilution flexibility/ capabilities of this product
