Dry ice & interior carpet replacement

[thenative1]

Morning all,

Carving this question away from a recent post to ask if anyone has advice/experience with removing old interior carpet adhesive/gunk using the dry ice & alcohol method?

I have previously replaced carpet on an '89 FJ62 and just used a stiff brush and elbow grease. Came out fine but would like to get a cleaner result this time as I prepare to install sound deadening and replacement carpet.

Thanks in advance!

I used dry ice by itself. I crushed it and then spread it out over the old sound deadener. Worked great. Wear gloves!

I used dry ice on an old BMW 2002. Worked fine, just not exactly easy or quick.
Why would you remove the sound insulation? I only did it to lighten my little sports sedan. (I was in Northern Westchester at the time BTW!)

If you're going to add sound insulation afterwards, it kind of defeats the purpose. BTW, people who add sound insulation usually treat the interior like it's a beer cooler and cover every square inch. That's exactly how NOT to do it properly, Planned placement in key areas is the way to go. Plenty of Youtube videos on the topic.

Agree on the placement (now that I beer coolered mine). The sound deadener changes the resonance (oil canning) of the panels. Over top you need mass loaded vinyl or similar for isolation

Preach, sir.
So much overkill when butyl backed sound deadener is spread like wall to wall carpeting. Can’t imagine what it would be like to remove all that if needed. My bigger concern with 100% coverage is if any moisture gets under it.

Unless there is an underlying issue with the factory tar.. you should 100% leave it. It about 20 times better at its job than any dynamat you can buy.

The 60 really needs help in the doors ( and rear quarter panels) and roof. The floor is pretty good as far as resonances. Instead look into a material that’s for road noise like the “luxury liner” or jute, etc.. that will actually make the ride quieter.

So true on the doors. I sound deadened my doors with a dynamat like product. And like I mentioned above, it did not require wall papering the whole inner skin like seen here so often. 60 series doors have a top, middle, and bottom section...each section just needs a decent sized rectangle of 'dynamat' stuck on it. Then covered the inside of my door cards with a thin foam deadener(forget the name), works great!

My doors sound like a bank vault. My untreated rear quarters sound like an empty beer can.
