That one Tuesday where every door kept reversing on me
I was working on a four-stop hydraulic in an old building near downtown, and every single door kept reversing like it had a mind of its own. Turns out the door edge sensors were coated in this weird sticky dust from a nearby bakery (maybe flour?), and it took me three hours just to clean them all. Has anyone else run into random environmental gunk causing false reversals on older safety edges?

A buddy of mine who does restaurant maintenance told me about a similar nightmare with a walk-in cooler door at a bagel shop. The edge sensors kept reversing because of a film of grease and yeast that had baked on from the steam vents. He said he spent almost half a day scrubbing them with degreaser before they finally started working right. The owner was just standing there saying "it's been doing that for months" like it was no big deal. Drives me crazy how people let stuff get so bad before calling someone in.

Nah, a little dust doesn't sound like that big a deal.

The bagel shop thing is a perfect example. People just accept stuff breaking slowly until it's a full crisis. A little dust today is a clogged fan tomorrow. It always escalates.
