It’s true…I’ll have to get a fly barf picture to share with everyone…at dinnertime…
I worked at a sub shop in high school, it had white, plastic-y walls. I remember being behind the counter watching a fly land and just observing it (…I do also have a bachelors in biology). It pooped on landing and flew off 5 seconds later. It’s poop was hard and difficult to scrub off - and similar black spots were all over these white walls. …
Abrasives on vinyl?
It’s poop…too yucky…I pre wet the windows and frames and white wood trim with Simple Green…boars hair wfp…frst clean in 3 yrs…they came out perfect…touch ups were for some paint os and concrete splatter…minimal. Doing the wood trim really made them pop…they were all speckled up too.
Try GREEN WORKS ALL PURPOSE CLEANER BY CLOROX, SPRAY LET SIT 15 seconds then wipe off longer if necessary quickly disloves.
