Had a job a few days ago and am looking for advice on cleaning these skylights. There are three 10’ panels side by side, and were covered in pollen. There’s no access to them except from above or below to hit with a pole.
I scrubbed them 5-6 times, rinsed, and then squeegeed, and they came out pretty good until the sun hit them, and there are a bunch of microscopic white dots from what looks like reside from the pollen. It doesn’t seem to come off with just a brush, and no way to get close enough to use a pad.
It’s a problem for the lady having the spots there. So, i’m wondering if anyone has any suggestions… maybe there’s a solution to break it down?
Here’s a few pics from the inside with the sun on em.
It almost looked like some kind of stain that got sprayed somewhere, as it’s clear. She said nothings been done since last year though. The reason that i thought it might be pollen is there was a lot caked on… thought maybe it scrubbed down to these spots… and they aren’t coming off for some reason.
Quick follow up on this project: it was tree sap, almost positive.
Coated the entire pane of each skylight with goof off, and then used the white pad with pole to scrub. Worked like a charm and even got some paint over spray that was lurking around.
