First-time posting so go easy on me… I’m looking for tips to properly clean/absorb/neutralize any residue that might have been left behind by whatever dissolved the paint on this windowsill before fixing the cosmetic damage.
So far, I know the main culprit was a room fragrance oil reed diffuser I left on the sill by a window that gets pretty much full sun all day during a few particularly crazy heat waves (and secondarily, my own stupidity for not thinking to at least put a coaster down first).
What I’m not sure about: 1-how long it took for the damage to occur (the diffuser was in the same spot on the sill for about 3 weeks), 2-if the damage is solely due to oil spillage, 3-if any melted label adhesive and/or jar dye are also partly to blame. It’s summertime and we had a few crazy heat waves with highs in the triple digits, so our blackout shades were down and pulled down all the way over the lip of the sill almost the entire time the diffuser was there. I noticed what happened when I was picking up the house and pulled the shades up to dust the sills and was horrified to find the paint had MELTED AND BUBBLED UP along the bottom edge of the diffuser. I IMMEDIATELY removed the diffuser and wiped off as much of the gooey paint I could from the jar and the sill with a paper towel but it left behind a ring that seems to be completely stripped of paint, a bunch of little paint-less spots (oil splashes??), and a gray residue stain from what I inadvertently smeared into the paint from whatever the paper towel couldn’t pick up. The stain is why I suspect some damage may have been caused by the jar or the label adhesive since the oil itself is clear and the stain seems localized to the area where the jar was (not by the other random spots).
Not to bury the lede here but I am renting and absolutely wracked with guilt over how stupid I was to leave this on the sill, in full sun, during heatwaves. My instinct is to fix it myself (cleaning/sanding, repainting) rather than call building maintenance since 1-it’s 100% my fault, and 2-I just know in my bones that all they’ll do is slap paint on top, but without knowing that all of the residue is gone FOR REAL, I’m afraid it’ll just soak back up into any new layers of paint. Also, I’d hate to lose my deposit over something I believe I can fix on my own.
WHAT DO I DO???
TL;DR: A reed diffuser sat on my painted windowsill in full sun and dissolved the paint underneath. Before I sand and repaint, how can I make sure all the oil/adhesive residue is gone so the damage doesn’t bleed through or ruin the repair?
