The joy Of Citric Acid

[The_Yellow_Ardvark]

Why do I use Citric Acid.

Well, use it cold it will remove the rust, allowing you to crack on with other projects.
Hot, it speeds it up and the playpen gets warm.

A WAFU glue pot, the inner one was long gone, sad.

After soking in Citric acid for a week.

I'll have to remember this. I've recently been gifted a Drummond lathe on which there are several rusty parts. Where/how do you obtain the citric acid? Can you buy powder by the kilo or are you a lemon squeeze? 🤣🤣

Try electrolysis. Plenty of info. on it.

I do that as well.

I use solar panel to give me a dc voltage, or a converted computer psu.
For the Land rover chassis I used a paddling pool and a old arc welder.

Citric acid can be bought by the kilo off ebay, amazon, or online suppliers, its often used as a food additive & for cleaning industrial kitchens. Quick & easy & works, good for cleaning up old files As the action tends to sharpen the teeth a tad.

2 lemons cut in half and some toothpaste make excellent washing machine cleaners, chuck them in on a long cycle and they will clean and deodorize

Be careful if you go to the pharmacy asking for citric acid.

My mum, a well to do lady in her then mid 60s wanted to make lemonade and the recipe required quite a large quantity of citric acid. When she asked the pharmacist they looked at her apprehensively and scurried off to the back. She reappeared a moment later with another staff member who went on to quiz her on her intended use for said acid.

It turns out junkies use it when administering a dose of smack.

As you can imagine, mother was aghast at the suggestion she might be a lady of ill repute!!

What kind of dilution rate do you use it at? How much acid eating juice would I get if bought say 1kg of citric acid?
Thanks.

I use about 1 table spoon per liter of water.

Then on used fluid I top up with 1 table spoon per 3 liters of water.

Also great for descaling the kettle

One of today's little jobs is to mix up some citric acid paste to spread around the tap heads in the bathroom.

I also use it in some of my chili sauce recipes, as a preservative, instead of vinegar.

At work, in the pharmacy (six hours a week) I recently learned the reason that we offer citric acid with our needle exchange scheme. It's because brown heroin is rather insoluble, whereas white heroin is more freely diluted with water. Citric acid (and ascorbic acid from vitamin C) in the presence of heat, helps to make the product soluble enough to be drawn up into the syringe.
