Pro’s Killer Kit #02 Microfibre cloths
I don’t go anywhere without a set of three microfibre cloths for wiping spray and sand off filters. I use one to get the worst off, a second to get the filter properly dry, and a third to give it a final wipe down. That way only the first one gets properly wet, while the last cloth stays reasonably dry. It also helps if they’re all different colours, so I know which is which in the heat of the moment! I make sure I wash and dry my microfibre cloths after every shoot so that I don’t run the risk of rubbing sand and grit from a previous photoshoot into my expensive filters.
