CIP chemicals

[lael]

Hi,

Thinking through a new rig design and thinking CIP. Does anyone currently do it effectively?

If so - what are your practices?

What chemicals are usually used for CIP?

Thanks!

Sorry, Lael, but with over 1000 posts, you're asking THAT question now??

'Thought you'd have that sorted by now.

normally caustic and an acid based sanitiser

 

[lael]

caustic soda? Is that a strong alkaline?

hehe, yeah, slow learner right? finally figured out I don't like cleaning...

 

[MartinOC]

No-one likes cleaning, but it's an essential "given" for anyone that wants to make consistently good beer. It's a no-brainer!

Caustic or BPW is your first point,

 

[lael]

Where do I source caustic and how dangerous is it?

 

[barls]

yep.
caustic then an acid.
generally brewsol and proxitaine is whats used in the industry.
id avoid it if you can its horrible stuff

Orrible stuff..

I go with a perc/met mix for my HEX which is CIP + starsan flush if I'm feeling the need

 

[lael]

just go with pbw?

 

[lael]

Yob - have you ever compared the effectiveness of your mix to pbw? how does it fare?

 

[Yob]

Only ever bought PBW once, since then I buy percabonate and metasillicate in bulk. On par as far as I know **** is clean

 

[lael]

Nice

 

[MartinOC]

Sure, proprietary PBW is best, but the mix of Perc./Met. will get you 95% there. 'Dunno what the extra 5% is supposed to do, but it certainly achieves it.

I think I was reading something on hbt about this topic - I'll see if I took notes on it. Anyone else know?

Ebay will have it http://pages.ebay.com/link/?nav=item.view&alt=web&id=231257747191

And I think bunnings have it in 2l/kg bottles in the same section as methanol etc

 

[MartinOC]

Seriously, Lael. Just go with the Perc./Met. mix & run it HOT through your rig & you won't go wrong. No need to research or explore any further. It works!

 

[lael]

sweet - thx guys!

Caustic is sodium hydroxide, strongly basic.

I was under the impression that was what a lot of commercial breweries cleaned with. Apparently it is much more effective than an acid based sanitiser.

You can get it as drain cleaner, or as an ingredient to make soap. Very hazardous and ppe necessary when handling.

Apparently caustic at 70 degress plus is nuke city
