Best way to remove dried dirt from inside the front frame (B)

I have a bit of an issue. I was doing my under coat and I shined a light into one of the holes in the frame located in the front wheel well and saw a bunch of dried mud. Hopefully there is no rust but there is absolutely no room to get inside and clean it out.

I want to spray a coating on the inside but I don't want to have a ton of dried dirt when I do that. The photos show what I see when I look through the hole. I don't have any room to fit tools in and even if I did there is no way to remove the loose dirt. Dirt inside the frame is also an issue with one of the crossmembers too.

What is the best way to clean the inside of the frame?

This is being reposted here for exposure, I need al the help I can get for this one. And its not like its an issue that is out of the realm of possibility for any generation.

 

Maybe you can chip it with a screwdriver then hit it with water and keep at it until it flushes out. I had some of that stuff in my old Landcruiser and a bit of persistence helped.

 

It would be nice if I had a vacuum of some kind...

 

This speaks to the problem of fording muddy tracks on the trail, and not thoroughly pressure washing afterwards. It’s a really big job to get all the sediment out of all those nooks and crannies. But once it dries, it’s even more problematic. I’d try a strong vacuum. Seal up any other holes with tape, loosen the mud and see if it will come out. Once most is gone try blasting the residue. Whenever I see a 4x4 in a shop I can’t help but look at it underneath, and I can usually tell the type of life it’s had by the amount of trapped sediment it is carrying.

 

Wishing I had done a better job of that because I can't shake the feeling this truck lived a life that goes against what the past owner told me. Who knows maybe it was the original owners fault, but it doesn't change the fact it went off road and now I am afraid to see what is waiting for me under that mud.

 

Be positive! Once you get it cleaned out you may want to give it a blast of fluid film.
