This sounds ridiculous but I was Googling forever to no avail.
We have been scrubbing like mad for four years with all purpose cleaner.
I’m not sure what kind of product to use to clean or clean off the adhesive that’s trimming all of our vinyl windows at the window-sill interface (we had these windows installed in 2016 and no amount of elbow grease has helped).
Thank you for any help you can provide!
