I'm curious to see some setups myself.... anything that saves time and effort interests me.
I'll start with a photo of my belt,
I adjust equipment to each job but here's my daily setup:
from left to right: business cards/steel wool in pouch... double loop pouch ( w/ magnetic blade holder, invoice book, 6" blade, almond scrub pad, sponge, pen, towels)... screen lanyard... multi-tool... screen brush, 6" squeegee, and BOAB w 18" washer and squeegee.
missing: I carry a tooth brush for detailing interior tracks and frames and have a clip on water bottle carrier for roof glass/skylights.
the invoice book is carried for store fronts/restaurants (saves time not running out to the truck every time I complete a job), big blade is strictly N/C and paint removal, screen brush is exterior residential (of course), and the 6" squeegee is accompanied by a 24"/36" squeegee if needed, depending on the size of the glass.
it looks like a lot but, it's a pretty comfortable setup I've been using for years on every job.
sometimes I do feel like batman though.... it's nice to have just about everything I need on hand.
