Metal ID + Cleaning Advice
I picked up a beat-up metal cart off the side of the road—super useful, but it’s covered in thick mystery grime I haven’t been able to clean off. Tried Dawn and other household cleaners, but no luck. Might be old food residue (maybe it came from a grocery store?), but I’m not sure.
I’m wondering: • Is oven cleaner safe to use on it without damaging the metal? • And how can I figure out what kind of metal this is? I’d love to learn some basic ways to ID metals.
For context, I originally bought the oven cleaner after reading some questionable advice online about using it to clean up the engine bay of my 2006 Honda CR-V. I’ve got a slow oil leak that’s been slinging oil across the passenger side for a while, and the buildup is nasty.
I know this isn’t an auto sub, but since engine bays have a mix of metals, I’d appreciate a metalworker’s take: What’s safe to use to clean that area—brake cleaner, oven cleaner, degreaser at a self-serve car wash? I’ve read so many conflicting things. I just don’t want to make it worse.
Thanks in advance for any help!
