I stripped out my carpets and wire wheeled/vacuumed off the padding and loose material. Anything loose is gone, but it still has some grunge. I'd like to clean it before laying down adhesive sound deadening pad, mat and rubber flooring.

Any tips, tricks or recommendations?

Side note: the passenger area sound deadening is toasted dark brown, guessing cooked from the catalytic converters. A lot of heat must be generated there!

That sound deadening needs to go...dry ice and a dead blow for the win.
 
When my 80 was in that state I pulled all of the drain plugs and then got after the floors with dish detergent, simple green, a scrub brush and water hose. If you do this on a hot day and avoid spraying the dash and electrical stuff directly there's not much risk in my opinion. Any water should dry pretty quickly once you are finished and if you leave the 80 out in the hot sun. There's no need for high flow or spraying with the water, a gentle stream to flush away the dirt/grease/soap as you scrub should be sufficient and help keep the water in the floors.
 
If you want to remove all of the factory sound deadening you can try the dry ice method or you can use a heat gun and a plastic spatula. If you wire wheel and/or grind/sand down to the metal then you will lose the factory primer coat. Take a look at post #133 in this thread and you can see how I tackled this problem in my FZJ75:

Thanks, this is exactly what I was looking for. Much appreciated.

Thank you all for the other ideas and input.

If you don’t want to get so abrasive, I have some shower cleaning time brushes attach to an electric drill. What rubber flooring are you going to put down? I’m basically the same step.
 
I went with Tru-Fit.

IMHO I would not use a grinding disc or wire wheel on the floor, that would just ask for rust to start. If you're going to remove the original material use dry ice as described in previous threads or on you tubby, however some others who have removed all the original stuff then put down new said it didn't help all that much.

As mentioned above, wash it down good, let dry, then apply whatever you're going to use over the factory sound dampening material, might help, but might be better to add a thicker carpet, underlayment, sound blocker, etc. Fix any surface rust before you lay down anything of course.

Applying sound dampening (Dynamat etc) to the door skins (sheet metal), quarter panel skins (~50% of the inside surfaces) works well. Then make sure the glass runs and weatherstrips don't leak (let air in): anywhere air can get into the cabin also lets sound in. You can do the same to the tailgate, put some patches of sound damping material on the inner aspect of the sheet metal (inside the cavity).

After that you can add a thin sheet of sound blocking materal ie: backside of door panels and cargo area panels. There's not much room for thick materials behind the door panels, 1/8" closed cell foam is what I used.

FWIW
 
I am putting sheets of adhesive sound deadening and then dynamat underlayment under the rubber.
If you don't put the adhesive backed sound deadening directly to the metal (or painted/primed metal) it won't do anything.....or not much of anything. In other words, you have to remove all the factory sound/heat deadening first.
 
Found a place that sells dry ice pellets by the pound. For anyone that has done this (@WarDamnEagle), how much dry ice did you use to remove all of the factory sound deadening?

I have not tried the dry ice method. It seems like the last thread I read on that subject the person used dry ice and alcohol mixed. I would certainly go big if I was trying it. Off the top of my head, FWIW, I would maybe buy something like 30 lbs and decide when I got home whether that would do both sides or just one side.
 
I think I bought a 10lb block when I did mine. It was the smallest amount I could buy and it was more than enough for both sides. Before you install the vinyl floor lay it out in the truck and park it in the sun for as long as you can. I installed mine in the winter and it was a challenge. Good luck. You’ll love the vinyl floor.
 
I just picked up 30 lbs of tiny dry ice pellets (from a local ice cream place that uses dry ice blocks for shipping). I'll give it a go tonight after work and report back.
