Is this coolant bottle cleaning with acid video legit?

What is H3NSO3 and does it do any damage to plastic? This would be a more effective method than my current way of cleaning them as long the bottle doesn't disintegrate after a week. And if he didn't just get a brand new bottle to fake the results.
 
Sulfamic acid-it is very good at removing scale (such as hard water deposits) from metal and plastic-just make sure to rinse it really well with water afterwards. Like citric acid, but stronger.
 
Why? No need to recreate the wheel when proven cleaners are available that are cheaper and proven. Youtube is not the end all source, most of the stuff on there is inaccurate and some tips or procedures can lead to major damage. Would you eat a Tide pod? Or mix HCl with pool shock? Both of those seem innocuous but they can and will kill you. Youtube is NOT a reliable source of information on ANYTHING.

Years ago a pal had 2 or 3 ounces of a "swimming pool" cleaner which restored our coolant reservoirs to snowy white. AMAZINE RESULTS!
The label was gone so we never could identify the product.
Hmmm....H3NSO3 or sulfamic acid might've been the stuff. Thanks all.
 
If you can get it out, add some Dawn and water and shake.

Putting car parts in dishwasher is allowed if wife is out shopping. For people with Mercruiser, putting the flame arrestor in the dishwasher is standard practice.

OEM coolant storage tanks are often very inexpensive. Not sure there is a lot of benefit cleaning old when when a new one often looks so much better, and may offer better reliability.

I use degreaser and a handful of steel pellets. Cleans it out good but not white like this method. What's the dishwasher for? Just rinse under a faucet.

$50 to over $100. OK on a $10,000 car but not worth it on a $2000 one, and likely discontinued.
 
Why clean a coolant reservoir?
Helps sell a car.
You can't always find a replacement.
Replacements are often cheaply made.
After a repair, remaining dirt in a coolant reservoir gives the appearance of no repair having been made.
A clean reservoir shows clean coolant.

We're pretty easy going, i.e. we let the cat finish off excess sauce from our bowls...they're family, but there's no way in God's World anything with gasoline, diesel, exhaust schmutz, brake fluid, transmission fluid, caked-on engine grease, gear lube, auto polish, defogger, glues + sealers and "aromatic plastic" parts is EVER going into our dishwasher. THAT'S totally a high school boy thing to do....not a youthful thing, a stupid thing.

Car juices cause cancer.
Wasn't there a Greek Mythological character who washed car parts in Aphrodite's dishwasher?
He paid epochally for that IIRC.

As long as it's not a Dorman aftermarket one...

Yeah the fact that they are plastic and pressurized and therefore tend to crack and leak, and are basically a routine maintenance item like plastic side tanks radiators does make me wonder if I should preemptively replace my > 20 year old one. Or maybe just replace it and try to clean the old one to see if I can swap it back in at some future point in time.

My only real issue is that I can't see the coolant level in mine any more without removing the cap.
 
Old thread i know, but does other acids also work? I'm thinking about hydrochloric acid mainly, readily available and cheap. I'm also curious to know if bleach works to whiten a coolant or washer fluid reservoir.
 
Watching the OP video and the below videos- I can't see where cleaning an overflow tank is comparable with simply installing a new OEM tank,
