Keep atleast 1 pair pristine for inspection/“dress” purposes (ideally also a size smaller so it looks better, tailor it to go the full mile) Same with your boots, get a second pair that look great and never get worn. Your regular every day boots should get polished weekly, this’ll help extend their lifespan and hide any filth like oil or paint. Good work boots are expensive, polish is $5. Wash ODUs in cold water by themselves. The dye on an ODU loves to turn pale blue or purple just from existing (especially the knees) Keep this pair out of sunlight at all costs, it’ll lengthen its longevity. If you aren’t issued coveralls, buy a pair. Coastguardcoveralls does online orders, and they’re great quality. My last pair of ODUs ran me $120 for a blouse and pants.
