Descaling a coffee machine (Nespresso etc)

Re: Descaling a coffee machine (Nespresso etc)
Well it's the system I use and I have no problem with it [checks: had 3 espressos this morning, and they were better than ever /checks]. And the bonus is what I saved vs the branded de-scaler will pay for another 40 shots, or come to think of it 80, when the non-$Gn-priced ones on their way from Europe arrive...

For the Baby sterilizer / food warmer the citric acid solution provided by Philips didn't work well, scales remained

Re: Descaling a coffee machine (Nespresso etc)
I use white vinegar every 3 or 4 months in my Mr. Coffee drip coffee maker. Fill with 50/50 solution run about half of it through then let it sit for 15 or 20 minutes, turn back on, run the rest through, then 3 or 4 runs with fresh water.

Vinegar is dilute acetic acid (typically 5%).the lynx wrote:I have never tried artificial vinegar yet and I have not studied the pros and cons of using the even-cheaper vinegar.
"Distilled" (or white) vinegar is made by fermenting distilled alcohol (ethanol) using acetic acid bacteria.
Synthetic or "artificial" vinegar may be made from non-plant sources, bypassing the alcohol step, which may be important for anyone having certain dietary restrictions.
For cleaning, it should not matter if the vinegar is artificial or "natural."
Just remember that an acid is corrosive, which is why it works on cleaning scale.
The 50% mixture with water should be safe for hotpots, kettles and coffeemakers, etc.
Be sure to rinse thoroughly (as already noted).
By the way, vinegar can also be used to clean vegetables and fruit.
There are also Youtube clips showing it being used to clean washing machines.

Actually, for scale, it works by neutralizing the resulting alkali solution from the mineral deposits in hard water (and detergent residue), usually calcium compounds.maneo wrote: Vinegar is dilute acetic acid (typically 5%).

The corrosion works on everything else.

The Chemistry definition of corrosion is a process in which a solid is eaten away, that is, changed by a chemical reaction.nakatago wrote:Actually, for scale, it works by neutralizing the resulting alkali solution from the mineral deposits in hard water (and detergent residue), usually calcium compounds.
The corrosion works on everything else.
Limescale is an insoluble solid, mainly calcium carbonate.
It is no longer in solution when it has precipitated out as scale.
However, an acid will break this up into soluble calcium ions, CO2 and water (H2O), effectively dissolving it away.
"Corrosive" substances, like acids, are just highly reactive.
Vinegar, a dilute weak acid, is just easier to handle and control.
Lime juice and lemon juice (i.e. citric acid, as mentioned earlier) would work just as well for hotpots and kettles, when followed by thorough rinsing.

Re: Descaling a coffee machine (Nespresso etc)
I would expect what happens to the scale and the acids is mostly happening on the solid-liquid phases interface. True that scale is water soluble (giving right condition, for example pure water, right temperature, sufficient time) so Maneo is a bit incorrect here, but IMHO this process for what we discuss is negligible. What the acids do to the scale is formally a corrosion process. Predominantly at least. Sorry Nak.

CaCO3 + 2CH3COOH -> Ca(CH3COO)2 + H2O + CO2
I still think that corrosion is the predominant mechanism for most household uses if the vinegar is cleaning something that is not so alkali. Descaling would primarily be a neutralization. But in the end, vinegar cleans all by oxidation.

And now, a word from our sponsors...
This very exciting and riveting discussion of "The Chemistry of Using Vinegar to Descale Household Appliances" is brought to you by:
ACME White Vinegar. ACME White Vinegar is distilled and made from sun-ripened grain and crystal clear water. With a clean, crisp flavor, it's ideal for your favorite marinades, salads, and recipes. Also, due to its mild acidity (5%), it is a great all natural helper around the house for cleaning and other chores and at a fraction of the cost of chemical based products.
ACME White Vinegar is available at all leading supermarkets and retail outlets.


*ACME White Vinegar is not a real product and is definitely not available anywhere. This post is a parody and is only for humor. If you think this is a real product, how gullible can you be? Ask your doctor or cleaning person for professional advice.

Re: Descaling a coffee machine (Nespresso etc)
Thank you for the tip on the artificial vinegar at NTUC. I use vinegar currently for my kettle and nespresso machine.
JR8, nespresso capsules are slightly cheaper in UK compared to here. I tend to buy tons when I am there.
