Asbestos paper-like material on sides of cold air return
Get a quote for removal or if you're uncomfortable with all of its hype, then definitely have someone else get rid of it. Do get rid of it, don't pass it on.

But, here's what you're in for if you're adventurous &amp; it's accessible, water is the key &amp; removes all of asbestos' harm.

Of course, get an N95 mask, goggles, nitrile gloves, duct tape &amp; disposable jumpsuit with a hood. All go in the trash, wrap them in the tarps.

Tarp the floor &amp; whatever else you can with a disposable tarp (tape multiple tarps together for verticals running onto horizontals) as this will be your final clean-up &amp; catch-all. You actually want to tuck the floor's tarp edge in your belt &amp; not actually walk on the tarp's top side (so you don't track anything out of the work area). When everything's done you'll water-down again &amp; brush one last time onto the tarp.

But first, it's just a water soaking &amp; clear bag wrapping process (in that order) to then pull, scrape &amp; brush it clean off within the bag. It's not radioactive like some people try to portray in its "danger". I've done it 6-times over the last 20-years &amp; I don't have any asbestosis whatsoever.

You'll want to rinse off the sealed bags outside or down a drain along with the tools after each section is completed. Like above, the tools get left in the rolled-up tarps. Remove excess air from the bags outside &amp; then double bag everything so trash-men nor anyone else aren't accidentally exposed.

The next day you can brush-paint over the areas to remove any doubt &amp; lingering "danger". Toss the brush &amp; paint, because OMG...I'm kidding but you can for a clean &amp; clear conscience &amp; refreshed Aura. This is all way overkill &amp; asbestos is in everyone's air &amp; always has been. But, done &amp; done right aren't the same thing &amp; no-one should be unknowingly subjected to any bulk amount of fibers.

Let me know if I left anything out, please.
