I think there is a self serve on Atlantic Avenue. If my memory serves me correct, it’s between A1A and US1. Most of the other washes I have seen in the area are full serve. I think Sonny's has one on US1 in between Ft Lauderdale and Pompano Beach.
There are a lot of washes in the area. What type do you want to see? There is a self serve on Floranada between Federal and Dixie. There are several touchless at gas stations and there are a bunch of tunnels around as well.
There's a self serve on Atlantic just east of Dixie on the north side of the road. There's one on Commercial just east of the turnpike on the south side of the road. There is one on Floranada between Dixie and Federal on the south side of the road. There's a huge one on Mcnab just west of Rock Island on the south side of the road. If you want more let me know.
