Using shaving cream to clean car seats is an old DIY that people still tend to use. You sure can use it in case of emergency, but we suggest not using it on daily basis. Also, if using shaving cream, always go for non-gel ones like those that are foam-based as they do not harm. Thus, when cleaning, apply the cream to the stain and rub it well. After this, use the wet rag or towel to clean the surface and let it air dry.
