View Full Version : Whats in your spraybottle?

I was wondering what people used in their spraybottles to surface "sanitize" hose connections, zwickles, etc. The two I have seen most are ethanol 95% and iodophore. I included a couple of other sanitizers which I woldn't use for various reasons but some people might.

Isn't Starsan an anionic sanitizer?

yes, I think it is.

I have used isopropyl alcohol, PPA, and stan san.

I use PPA but in a strong concentration:10%. for non-rinse its 1-1.5% (of a 5% product)

For what it's worth, the 95% ethanol option brings to mind the fact (as I remember it) that a more dilute alcohol solution, be it isopropyl or ethanol, is supposed to be a faster kill. Something to do with the higher water % allowing it to enter the cell faster I think. As a result I think that a 70-80% alcohol may be more effective. Just another case of more is not necessarily better. Anyone else able to corroborate?

I believe the other factor is evaporation. The 95% just evaporates too fast/more kill time with the 70%.

I use galens 151 vodka, gives about 75% ethanol and is fairly cheap at $12 per 750ml as well as being easy to tag onto our bars liquor order.

I wonder why nobody has an anethol/ethanol product on the market?:confused:
It works great and smells/tastes awesome. I make it and use it for my needs. EZ. I distill it from sweetroot.;)

Kinda like potent Ouzo.:cool:

Google and check out anethol.

I use the ethanol and flame when I'm taking samples for plating.

A lot of the time I use ozonated water, and I'm surprised more people don't. You can't put it in a spray bottle, though...gotta come from the ozone machine. I played with the idea of running hose to each vessel, and having a coil hose and gun to spray with, but I've never gotten around to it.

I find the 70% doesn't flame as well, but I use it around the rims of carboys when I'm doing wine, and if I have to rest the lip of something on a vessel (like when I'm filling the brink)

Does anybody mist the air around the filling area when you are dealing with yeast? I had one guy do this...felt like a waste of material, but I never had any problems with his transfers...

70% iso alcohol.
Best I have used.

we just use standard diluted iodophor sanitizer.

Star San. Now adding more text to make message long enough to post.

We use Star-San. If it's below 3.5pH it'll kill up to 99% in 30 seconds, according to former owner Charlie Talley.

A word about Chlorine Dioxide as a spray. It kills at about 8 ppm w/ aprox 3-5 min contact time. If using as spray on application, it was recommended to us to use as twice that rate.

I use star-san in the spray bottle. It does double duty since it foams up when you are looking for leaks in the co2 system.

Star San in the bottle. Sani Clean for tanks and kegs.

I can't believe people are using PAA in bottles. I tried that and it was painful! It's making my eyes hurt just thinking about it.

70% ethanol.

Can't imagine using anything else.

PAA at no-rinse concentration is actually pretty benign. Not sure why more people not using it.

I thought PAA and chlorine dioxide only had about an 8 hour shelf life? Thats why I never consider them for the spray bottle though I use both for tanks.

alpet D2 surface sanitizer is by far the best sanitizer for sterile sample taking. you should be able to get it from your regular chemical provider. i've had 7 years of successful sterile sampling in the dirtiest of breweries by using alpet. its safe non rinse, and i never use a propane torch to light it up.

I second the Alpet D2...

Well said Brian. Welcome to the forum.

Iodophor is my choice. Mixed halogen actually.

Liam, doesn't iodophor "expire" after a while the way some of the other ones do? I go the anionic route for that reason.

liammckenna

It does.

As Brian mentioned, the test kits are your friends. ;)

He also mentioned the wild yeast thing.

I'm pretty paranoid about those wee beasties after losing a tank of beer 14 years ago.

Pax.

While I use PAA for sanitizing my tanks and HX, I use StarSan in my stray bottles. The foaming action and adhesion are great for sanitizing fittings and any exposed parts, such as sample vavles IMO.

Food grade, relatively safe to handle and works a treat.

Fairly fast kill rate and it does not degrade over time like iodine, PAA, or even Star-San.

Our brewer uses iodophore, but I swear by isopropyl and if I'm not in a hurry a flame makes me even happier, especially if I'm pulling a sample for my lab.

70% isopropyl, from costco.

We use PAA, seems to work great. Haven't had any issues. We use a slightly stronger concentration. It lasts about 48hrs in the bottles. Which is fine since we go through them quicker then that.

We keep a standard concentration StarSan solution in our spray bottles. I prefer how it wets & adheres to surfaces over other sprayable sanitizers.

We recently switched from Iodophor to PAA for our general sanitizer, but our spray bottle is still ETOH (ever try isopropanol in your coffee?). However, after reading this thread and doing a bit of research, we now cut it to 70%. Cutting down on our Clear Springs by 30% saves us money and we don't look like quite as much of a bunch of alkies....

Couldn't you get more shelf life out of some of the cleaners using distilled water to cut with? I know star San shelf life increases with distilled water significantly.

PAA--H2O2 (peroxide) rapidly breaks down to H2O and an oxygen radical, which reacts with danged near anything. The acetic acid volatilizes quickly. Iodaphor loses the iodine ions through reactions with anything organic, and the iodine also volatilizes. I don't see how either of these would benefit from using distilled water.

Not exactly sure why shelf life would even be part of the discussion. You should be using your spray bottles, not watching them get old. I have a spray bottle full of Saniclean for every tank and still have to replenish well before even having to give shelf life any kind of consideration.

It's more convenient and time efficient to mix at larger batches to fill a spray bottle with, rather than multiple smaller mixes.

a little late to the party but yes

70% is far more effective than 91% or 95% iso or ethanol

the water in solution helps assimilate the alcohol into the cell where it can denature proteins, not only that but 70% doesn't evaporate as quickly so it acts for a longer time, with stronger action.

in the lab we buy 91% isopropyl for flame sterilizing but dilute it to 70% for sampling tanks.
to dilute 91% to 70% is very easy
add 30ml of distilled water to 100ml of 91% and you have 130ml of 70%
