Forget the stepladder, bucket of suds and a squeegee - window cleaners for the Convention Centre Dublin must be proficient in abseiling to be up to their role.
Thankfully the rain held off for these thrill seeking workers who managed to brave the dizzying heights of the Centre's building frontage.
An adventure in itself, the team of window buffers successfully conquered the mountainous (and glassy) terrain in order to work up a decent shine.
"In my profession I work hard but I'll never stop," sings George Formby in the 1930s classic "When I'm Cleaning Windows".
Well these lads definitely earned an "honest bob" as they climbed "right to the top".
