Sulphamic acid?

Redsicks · Post by **Redsicks** » Tuesday Apr 18, 2006 1:55 pm

Has anybody used sulphamic acid for cleaning old beer bottles?
It is stuff dairy farmers use to clean their milk plant. It removes scale & all sorts of other nasties.
Hopefully it will disolve snail shit & rusty looking stains from a heap of old long necks I've found a while back.
It's a dry powder you mix with water.
Any body had any had any experience with this stuff?
I will mix up a small batch & try soaking a few bottles.
I will post my findings.

Personally I wouldn't be using this stuff when there are far safer alternatives around................

The stuff Im talking about is sulphamic acid , the stuff in the link you have given is spelt different(Sulfamic acid).
It could be the same stuff, could be different...?

Point taken about safer stuff being around, but not many powerfull cleaners are 100% safe.
Take "Sodium Metabisulphate" if I breathe fumes from that stuff I almost pass out... (the information on chemical data sheet on that stuff is as bad)

I'm just after a once of, thorough clean.
My Inlaws run a dairy farm, use it every day & have never had any issues with it in regard to skin irritations or respetory problems. Iv'e used it at the dairy too with no probs. Thats where I got some from.

I'm just wondering how it would go with cleaning glass & if any of you have tried it.

Sulphamic and Sulfamic are identical. Depending on where abouts in the world you're from. Some spell it 'ph' some spell it with an 'f'.

From reading the fact sheet I would be careful about rinsing. It mentioned (the second fact sheet posted) that the sol/n will be mostly Sulfamic acid and some "non-ionic surfactant", which suggests to me that it is not dissolved well in water. It may make rinsing hard (think about rinsing a tray of fat without detergant), and if this stuff is as bad as the sheet suggests (vomitting on ingestion ect.), I'd want to be sure I could rinse all of it away.

hmm...

Yes, I agree with the caution of thorough rinsing. I would rinse, then do my normal wash, steralise, rinse routine after.

It seems to be fine in dairy application.
Rinse with water, wash with the acid solution & rinse with hot water & drain.
Then the system is right to have the milk we drink go through it.

I've checked the drums that we mix the acid powder/water in & once the drum is pumped empty after the wash cycle I see little or no powder left in the bottom - indicating to me it disolves ok in water with only a quick stir.

This is how my inlaws use it & they are in the top 3% of farms for milk quality.

I havn't pulled my finger out & mixed up a batch as yet, but will post my results.

Well, I mixed up some solution & Its doing a pretty good job. Better than all other stuff I've used. Some bottles I'm letting soak again, but 2/3 of the bottles came up good after the first soak & scrub.
I'll use it again on my next batch of bottles I find.
Again, only for the initial clean. It is pretty potent gunk removing stuff.

I am only on my first batch of homebrew right now, so I couldnt tell you how well it works, but I did a cold water rinse, then soaked in Sodium Metabisulphide and finally a water rinse. They look clean, will keep you posted on if it works

Maybe it's just me but I get a burning feeling in my throat when I use Sodium met to sterilise my equipment. I'm staying away from it.

I'm just after a real powerfull bottle cleaner to get rid of very old & stuborn stains.
This stuff seems to do it. Old rusty looking stains have gone.

hmmm, no burning in my throat when using SMS, are you making it up to the concentration stated on the pack?

Redsicks · Post by **Redsicks** » Monday May 01, 2006 7:13 pm

I used to. Maybe I'm just sensitive to it???

Now I use Neo Pink for a quick wash & sterilise.
No isues.

It will clean, it is used in acid washes to remove the scale as you mentioned.

It will be pretty powerful as the will expect you to be diluting through a CIP system, not what you really have in mind, I use tank wash, which is a little lighter
