Is it ok for customers to add distilled vinegar to pump to prevent that already stuff? If so how often and how much?

And actually work. I think vinegar is excellent in pickles but not as a cleaner. [emoji1787]
My only cleaning uses for vinegar is to lower the ph of bleach water to make the bleach work and for removing calcium deposits if i have time to waste.

Vinegar will dissolve calcium deposits if that's what's being left behind. Try a bit. It's acetic acid. It should foam if the deposit is calcium. If not strong enough some HCL (hydrochloric acid) will cut it but use diluted. Called Muriatic acid from hardware store.

Vinegar as a household cleaner is actually very good and much safer then say a bleach. We buy it 3 gal at a time from Costco.

Does really well on our fake wood floors to clean and not streak. We wipe the kitchen down with it as our everyday cleaner.

Never used it for HVAC cleaning though.

I have been using "The Works " liquid toilet bowl cleaner for many years and have had excellent and quick results cleaning condensate pumps and drain lines. It's $1 for a 40 ounce squeeze bottle at Menard's, is more acidic then vinegar or CLR and does a nice job. Just rinse with water a few times afterwards. It also is excellent for descaling steam bath heaters. I only use food grade vinegar to clean circulator pumps in tankless water heater systems and other potable water systems. Also excellent for cleaning tile grout.

Off topic but if your coffee machine at home is sluggish or not working as well as it used to, buy a 32oz of vinegar and fill the receiver with it, and run the machine so the vinegar gets heated and pulled into the jug. run water through it 3 or 4 times after that to flush it. Whole process takes about an hour but it will make your coffee machine run like brand new again. Fast and tasty

Not really off topic Frosty. The minerals deposited in a coffee maker are some of the same and most common found in most waters. They give the taste to water and without them, water will be flat tasting like distilled H2O is.
Vinegar is about the safest acid that can be used at home w/o precautions like ventilation, gloves, glasses. I'm more likely to grab the HCL but not on the coffee maker.

Ordinary Table Salt will kill the Slime in the Condensate Pump. We used to put Rock Salt Down the Condensate Floor Drains at work to keep them clear. BTW, I Do Not Recommend Rock Salt in the Condensate Pump, it may jam the Pump up. The Manufacture of my Submersible Aquarium Pump, told me to never use Vinegar on the Pumps, it weakens the Plastic, and eats at the Ceramic. To use Food Grade Citric Acid, at two to four times the Food Prep Strength.

Also during the Winter, I put a Tablespoon of Salt in my Rain Gauge, after emptying, keeps it from freezing, and cracking.

Not saying things like this don't happen but vinegar does come in plastic bottles. I know there are many different plastics but I wouldn't be wary of using it in pumps. Citric acid might do the same thing but be less aggressive. Some much more aggressive commercial system cleaners I've run through pumps with ceramic seals with no apparent damage, just saying.
I use vinegar to test rocks for calcium and magnesium carbonates for identification or HCL if they don't respond by foaming. Rock hunting are another of my distractions.
The most aggressive I've worked with is Nitric acid. I used it to prep lithographic stones to remove the "Ghost" from previous printings. That stuff is nasty full strength. That mixed with one other is the only way I know to dissolve gold. Called Aqua Regina.

Still is. The concentration is not as high as it is scary though.
When gold was separated with mercury (still is with small scale individuals) it was said miners could wring mercury from their hands. The crushed rock was spread on a iron table and miners would mix the mercury with rock to react and create an amalgam like a silver tooth filling. Then the mercury was cooked off in a condenser to reclaim it. They were environmentally aware. The condensers I've seen had very tall chimneys. Send it to LA.

if your tools ever get rusty you can soak them in the vinegar, the heaver the rust the longer the soak...a weekend typically does it...i use a stainless small brush also they are cheap...you can see plenty of youtube videos about it..i use the wd-40 rust lubricant afterwards...
i have a tankless water heater and whitle vinegar is used to clean it out with a circulation pump..i do mine once yearly...

Two to Four Tablespoons, depending on how big the pump is. Also it keeps you out of any legal issues. I can just see a H.O. Going before a Judge, and telling them they had to stay in a Hotel, because the Tech. used salt, in their home. Also another thing I would use is Isopropyl Alcohol, to clean indoor coils, figured out how to dilute it to 50%, no matter if it was 70% or 91%. I had a lab supply, I could buy 100% in Five Gallon jugs.

That isopropyl alcohol on evaporator coils reminds me of a time that I used a foaming coil cleaner on an evaporator coil in a air handler and when I fired the blower up it foamed up the foam hit the capacitor and shorted it to ground which scared the crap out of me. Of course then I had to very calmly wander on out to the truck to grab a new capacitor without making it obvious that I was still shaking from jumping so bad. [emoji1787] I can just imagine something going wrong with isopropyl alcohol and having flame shoot out the supply grills instead of just an arc flash on the capacitor.

I know a lot of the stuff that's effective is not welcome by the customer. Especially if it has any smell. Some can be very paranoid.
I once gave the guys some kerosene. There were bearings on some commercial equipment that had been over greased for years. While it did an OK job of removing the old grease it also created a smell that emptied part of the factory.

But better than that, a two story office was emptied when a strange smell was thought to be dangerous. The fire dept was called and one of the TV stations. A slow news day I guess.
It was found to be a rotten orange in someones desk drawer. Seriously??

Those things don't bother most of us but civilians can react to about anything. Curious about that is the smell of heating oil will get a bad reaction from many except those that have heated with oil. To them it smells like comfort.

The short answer is avoid anything that smells, burns, explodes, or causes fear and panic with civilians.

To me it smells like light. when I was little we didn't have electricity and we used kerosene lamps for l for light so heating oil and kerosene just smell like light to me. [emoji1787] I think it's quite a pleasant smell but my wife can't stand it.

Better be wearing your sensorcon CO inspector around that thing. I know that's the first thing that goes on after my pants when I wake up in the morning. [emoji16]
I've had enough close calls that I figure you only get so many close calls before you don't get another chance.
