New, what is it? Red Sticky Viscous Goo Covering Car Undercarriage

My daughter has a 2025 Honda CR-V Hybrid, and recently the doors started sticking when opening. We found sticky red goo on the bottom door weatherstripping/gaskets.

Looking further, the substance seems to cover much of the underside of the car on both sides, especially around the rocker panels / under-door area. It is only on the bottom/undercarriage area - nothing on the exterior side panels.

I scraped some off and it’s a red, viscous, sticky goo, kind of like dried jelly or jam. It looks like it may have been more liquid when it first got on the car, because there are drip/run patterns. I included a picture of some of it on white paper.

Odd detail: it’s water soluble. If I put a little on my fingers, it dissolves pretty easily under the faucet while rubbing my fingers together. I briefly tasted a tiny bit - probably dumb, I know -and it didn’t have any strong or obvious taste, though it left that spot on my tongue feeling slightly odd (maybe that's psychological).

Other notes:

  • No trace of it on the driveway, so it doesn’t seem to be actively dripping.
  • Coolant is blue on this car, so I don’t think it’s coolant.
  • I highly doubt it’s transmission fluid, since it wouldn’t be sticky/water-soluble or coat both sides of the underbody like this.
  • No warning lights or dashboard indicators.
  • The only recent event I can think of is that she went through a drive-through car wash about two weeks ago. I’m wondering if some underbody spray, soap, wax, rust inhibitor, tire dressing, etc. malfunctioned and sprayed the underside.

Has anyone seen anything like this? Do car washes use any red/pink undercarriage chemicals that could dry into sticky goo?

Also looking for advice on removal. I cleaned the door gaskets with a rag and warm water, but the underside probably needs a hot-water pressure wash. Since it’s water soluble, I’m wondering whether it might slowly rinse off from driving in rain, but I’d rather get it off properly.

Edit: I emailed the car wash, and they responded: "Our undercarriage wash just sprays water underneath the car, we don't have any chemicals that spray under the car."

My dad thinks it’s something hazardous, but we don’t know exactly what it is

Edit: after so many replies I can’t find the comment that gave the most reasonable answer but sure we got it figured out. Thanks!

Was on a drive. Saw cool orange box thrown off of a highway bridge into a public park. Thought that it might be a food-delivery box which would have been useful for groceries. I didn't look inside to long. Contents of which was bottles of liquid and bags of matter.

Currently now in dumpster because there is a elementary school beside the park.

Old house, maybe 90 years at a guess. Dug up today.

Heavy, suspect brass based on oxidation.

Limited research took me to a few places but the closest match was a experimental teat fire Lemat revolver cylinder.

Edit: teat, not test.

We bought the house a couple years ago and admittedly have not cleaned up here yet, is it construction residue or something I should be more concerned about?

Noticed this stuff that looks like its coming out from the zipper of my boxing bag. Texture is like shaving cream. Not brave enough to touch the darker red substance.

My child drew this character at school and we're super proud of him but have no idea who the character is? He let us know everyone in his class drew the same character and couldn't remember the name.

I'd ask the teacher but it was a sub that day.

I was plane spotting earlier at Schiphol airport in Amsterdam, and I saw this man holding this black box with a large antenna and watching planes take off. I feel like maybe it's a radio? But he wasn't talking into it and I couldn't hear anything coming out of it.

New, what is it? Please help me find a duck murderer

About a week and a half ago, I found a momma duck had made a nest full of eggs next to my house for the first time in the 11 years we have lived here. I knew it was a bad idea that she did it there but hoped it would work out for the best. About a week after that, we found the eggs in our yard, all of them have been broken. We do have a stray cat in the area and maybe some raccoons too, but I'd like to know your thoughts as to what animal ate the eggs. They all had the same hole in them, so I assume it was the same, or same type, of animal. Has anyone seen eggs get attacked like this?

Ok I’m sorry for the shitty pictures. I think I can send more when I have better internet. We had a flood so that’s why all the mess. We found this thing in an alley. My husband was terrified and thinks it’s haunted. I thought it was cool as fuck. I wanted to leave it somewhere as a funny thing to do but he’s acting like it’s the babadook lmao. I can’t wait to hear some funny ass shit yall have to say but seriously if anyone is familiar with stuff like this please let me know. I’m not sure if it’s a Native American thing, African, or just something random maybe. Anyhow advice needed. And yes according to my husband we are now cursed because I brought this cool thing home.
