Meguiar’s Ultimate All Wheel Cleaner and a decent turbo nozzle will usually get ya 90+% of the way there. For the rest, chucking the right detailing brush into a 1/2” cordless drill makes it go quicker.

Everyone has skipped an important piece of information…
Is this OEM paint or has the hood been resprayed at some point? When I see this level of degradation it is almost always due to a low quality respray.
I had to deal with year old dried concrete once. Figured concrete is alkaline, so I used the only acid I had on hand - the red Meguiar’s Chrome Wheel Cleaner. Wasn’t a fun process but definitely got it handled.
Dude, you are my sort of people! I wipe my air/water/pressurewasher flexzilla hoses down with M40 and it does ok, but I’ll give them a proper cleaning via this method soon. Great post!
I've tried everything there is and I do this 10+ hours a day... Meguiar's M110 and M210 are my go-to 95% of the time and I keep a bottle of M101 close by for the extra hard stuff. With M110 and 210 it is IMPERATIVE that you follow the directions: slow arm speed and more pressure than you're used...
Yeah, the strain relief inside the machine is too tight and pinches the cord. If you're proficient with some wire strippers and don't mind making your cord 4" shorter it's an easy fix.
You definitely don't want to compound or polish over them. Tape them off. Come time for an LSP, I've had success using Meguiar's Ultimate Liquid Wax over the OEM matte Dodge decals/stripes (among many others), but definitely test in a small, inconspicuous spot before attempting the whole thing.
I've been having fun with the new 8k Trizact discs too! Had a newer black VW with some hammered paint that was as hard as nails. I was reaching for the M101 and a PFW pad when my 3m rep walked in and handed me a few 8k discs. The 6" disc with a fairly stiff interface pad HANDLED BUSINESS on...
I've got 2 25' Flexzilla hoses on my 2000PSI Ryobi (a 1/4 and a 3/8). Both are a huge upgrade. The 3/8 loses a little pressure but flows more water so I like it better for washing cars with.
I see that you've tried some very alkaline products (which would remove an acid based material). Try an acidic product just in case the black stuff is alkaline in nature. I ran into this once when someone drove through wet concrete (very alkaline). Hit it with Meguiar's Hot Rimz Chrome wheel...
I don't offer a 1-step, but there have been two cars lately that I got absolutely flawless with just D166. I knocked $75 off for each of those customers which landed them at $325 ($400 is my small, light colored car starting price here in North Mississippi). As far as I'm concerned, my...
I do a good many boats, I price them at $30/ft to correct all the gelcoat surfaces. $35/ft if the boat is black. The important thing to a complete and lasting gelcoat correction is to abrade away ALL of the oxidation. I accomplish this either via damp sanding with Trizact 1000/3000/5000 discs...
