car wash

Hi all, My first "real" post here, unfortunately it is an unexpected issue. I've had my FJ for about two months. It is a 2010 6MT that I bought used with about 165,840 miles on it. No apparent issues with it at all when I bought it. I live in southwest VA so it is basically turning summer...

I recently went off roading and found a cool mud hole to drive through along the way. This was my first time (going through mud since I got the FJ 1 month ago) and now that I am back home there is a ton of mud under the wheel well, suspension, under the skit plates..... basically everywhere...
