Attempted dry ice to remove sound deadening

[Thunderstruck95]

I bought 25 pounds of dry ice to help remove the tar sound deadening under the carpets and it was not the magic trick that YouTube videos show it to be. I believe this was said by others in the past on tstsnbn, but I’m putting it back out there for other automotive anorexics.

I spent about 2 hours working with the ice and and some rubbing alcohol, but could not get the tar to break up in any useful way.

I found that a heat gun and scraper seems to be the only way to remove the tar sheets that our cars were born with.

Has anyone else here tried the dry ice method with success?

Nope. But yeah, I'd go with heat. Ice will only make the tar adhere MORE to the metal. Not only will it be stuck in place it will be FROZEN in place.

I used a mini torch and scraper on mine. It worked pretty well, other than leaving behind some residue.

leaving behind some residue.

Couldn't that be cleaned up with some GooGone?

Yep, or diesel fuel. Mine was getting sandblasted anyway, so I didn't worry about it.

And diesel fuel. Does it strip paint too? If it does, I would see why you wouldn't care. But if doesn't, good to know!

That was my first thought when I read your post. I would have done that first, using a petrolium based solvent (gas?) and a scrapper and hours of fun doing it! Hope you got it all off.

That's a good idea! I never thought of that, but the heat would somewhat liquify the tar and make it easier to remove.

It shouldn't strip paint. We also used to use Kerosene, but that can be hard to find sometimes.

Neither strips paint. Actually one of the old school rust belt hacks is to use diesel on the undercarriage

Modern oil spray undercoatings are the same principle, just more durable.

Diesel on a snowplow blade is the old hack for keeping the snow and ice from clumping up on the blade. It also removes asphalt tar from paving machinery.

Don't let those communists at the EPA catch you doing any of this, though.

"... communists at the EPA... "

That's an oxymoron...

The modern spray undercoatings are pretty similar, they just add a few more chemicals to the mix, which you can do with the old school method as well, like diesel+kerosine.

Actually it's redundant.

My favorite YouTube car enthusiast has used it more than once, seems to work for her -

But maybe it's that machine she's using?
