Job is a large metal car depot, gutter runs are slim and tucked under the lip of the guttering shell. I took these pics on a mewp i "borrowed" from the yard. I tried using my vac (high powered indutrial gutter vac) but bc it didn't have any purchase on the base of the growing plants it didn't grip enough to remove anything. Curious on how these places get cleaned usually - fwiw i think the best way to clean these would be to unscrew the guttering sections and flush them out. Anyone else seen done anything like this please i would be grateful to know your experience.
