I’ve got some trips logged on my side trays and between using them as steps in and out of the boat and the dog tracking in sand I’ve got some grit to clean up. I usually just hit the trays with a hose and once with a light pressure wash, but the sand remains. I just would like to get it all up before a my spring oiling. It doesn’t vacuum really at all, maybe a scraper? Any ideas are appreciated. Thanks y’all
