Cleaning vinyl

409 is going to strip out some essential oils that are left in the plastic, so is armor all as users say it ends up cracking over time. Gogo with lanolin is my best recomendation. works great on weatherseals and window gaskets too. I wouldnt use harsh stuff like purple power or that .99 store yellow awesome stuff. It works great on grease and grime but it will take the sheen right off vinyl and make it harder to clean later.
