I recently rootled through one of our utility room cupboards, including the shoe cleaning box. Good set of brushes, the tins of polish had to go though as beyond redemption. Having said that, I do give my black boots a polish periodically, squeazy polish but real brushes. Others are trainer types and get a scrub in the sink as needed. My late Father was very fussy about his shoes, always polished, and the first thing he did when meeting someone for the first time was look at their shoes. He always said you could judge a person (man) by the care they took with their shoes, and their hands, he had a hatred of raggy, dirty nails too.
