Breville/Sage Touch Impress cleaning (backflush) cycle

ObM, 4 months ago

You can find the general compositions of the powders and tablets from the safety data sheets here: www.cafetto.com/safety-data-sheets

I managed to find a Breville SDS to compare (…amazonaws.com/…/Breville Eco Coffee Residue Clea…)

But from what I’ve seen, they’re all pretty much the same - Washing soda and an oxygen bleach (some brands add surfactants).

If you did it by approximate weight you’d be fine. But double dose probably wouldn’t make a difference either (the ingredients are easily dissolved).

I’d suspect the tablets contain a binder that might make them slower to dissolve.

If you want to get experimental, couch a spoon in one glass and a tablet in another and fill hald with hot water and see how long they take to dissolve.

I’m curious, but probably wouldn’t be curious enough to do it. I’d just Chuck in the scoop and give it a wash cycle and maybe an additional rinse (wash without powder) until the final rinse water from the clean cycle looks clear and tastes ok.

After a rinse or two I can’t imagine it’d be concentrated enough to case an issue from a tiny taste test (but I’m not a doctor, you do you).

Thanks for the comprehensive response! Much appreciated!

Looks like I’m overthinking it…

Yeah you are a bit but manufacturers do like to ham up the warnings, so it’s understandable.

I wouldn’t stress. They’re all so similar. The variations will need mostly proprietary differentiation nonsense.

The sodium carbonate might attack copper and aluminium at moderate concentrations. I suspect the concentration would be enough to do mild damage if you left it a long time (ever run an aluminium pot, ice cream scoop or kitchen gadget through a dishwasher? You get that crazed grey look). But the chemicals and the duration of the cleaning cycle wouldn’t give it enough time to do meaningful damage.

From a heath angle, the cleaning agents in these tablets are also reasonably mild (in the scheme of things). Probably better to err in the side of no serious chemical burns to customers’ throats (in case the cleaning cycle goes wrong). Sodium carbonate (washing soda) and sodium percarbonate are generally mild irritants - best if you don’t stick your eyeballs on genitals in a concentrate solution.

But they’re not particularly nasty compared to things like dishwasher tablets.

You’d detect the taste before you’d have issues.

Thanks a bunch for your detailed advice!

Speaking of manufacturers, apparently the Barista Touch Impress keeps an internal log of all drinks and maintenance activities performed on the machine. I also read on Breville’s website (or manual/warranty registration page?) that this log could be used by Breville to determine warranty eligibility. In other words, if the machine asks you to do maintenance and you keep postponing it, they may refuse to cover warranty service in the future… kinda ominous, if ya ask me… on the one hand I get it: why should someone that straight up neglected/abused their machine be offered the same warranty coverage as someone who always maintained their machine well, but on the other hand, this is some ominous big brother stuff… 😯

Good to know. But, so far we haven’t got DRMed cleaning tablets. So, when it asks to clean, throw in some random powder, push the button and let it do whatever it wants. I can’t see how they’ll ever know.

It pisses me off. Because I’d happily buy manufacturer brand consumables if they weren’t such scumbag assholes with their pricing. I might even consider a small premium if the product is decent but not 400% premium just because it matches their brand.

These assholes package up the same common salt-shaker-garden-variety-chemicals costing 1-2 cents per dose (which generic brands charge 10-20c / dose) and sell it for $1 a dose. Screw that.

Anyways. Fight the power. :) Good luck.

100% agree with you on this one. I entered this rabbit hole when I saw that Breville-branded cleaning tablets were made by Cafetto. Lonand behold, I found Cafetto tablets with identical specs on sale 10x cheaper than what Breville was selling them for. And powder was even cheaper, which is what triggered all this…

Really annoying and frustrating!
