Star-San vs. Iodophor - FIGHT!
Choose which sanitizer you use. Post why you use it, including your list of pros and cons.
I use Star-San primiarly.
Here's some Pro's:
Short 30 second contact time.
Bottle comes with measurement bubble.
Can be stored for months, as long as PH is below 3 it's working fine.
Rinse Free as long as solution does not exceed 300ppm (1oz per 5g)
More expensive than Iodophor. (63 cents per 5 gallons) (this does not account for storage, if you can re-use the same star-san enough times the cost becomes equal or less than that of Iodophor).
Testing PH is required after long time storage to make sure it's still viable.
If you have extremely high PH water you have to either treat the water or use a bottled water.
Undiluted Star-San can harm counter tops.
Foams up like crazy when agitated. (This isn't a true problem, but it bothers some folks).
Here's Pros and Cons for IODOPHOR
Cheaper than Star-San, 9.99 for 32 ounces equates to about 15 cents per 5 gallon batch you make (1/2 oz).
Rinse free as long as solution does not exceed 12.5ppm (1/2oz per 5g)
Odor can put people off
Cannot be stored long term, iodine tincure evaporates within 24 hours.
Exposure to heat and light can diminish shelf life of undiluted product.
"Odor can put people off"? What people? This stuff doesn't stink when mixed 1 cap per 4 gallons.
"Stains plastic". Yes, but the stains come out just as easily with some bleach water.
"Cannot be stored long term, iodine tincure evaporates within 24 hours." Only if you let it. I fill idle carboys and keep them plugged. The stuff keeps this way, in an open bucket, no.
"Exposure to heat and light can diminish shelf life of undiluted product."
Well, I keep mine in a 68 degree room that's kept dark plus I keep it in a drawer. Not an issue to me.
As far as I can tell, there are no cons. The stuff works well.
1) I can smell Iodophor at a rate of 2 caps (1/2oz) per 5 gallons (12.5ppm). 1 cap for 4g puts you under 12.5ppm.. so I dont see how you use it as an effective sanitizer.. that is unless you aren't using BTF Iodophor (other products may have a different amount per gallon)
2) Who wants to worry about cleaning their stuff with bleach to take away a sanitizer stain?
3) I've read numerous times that iodine will not stay at a needed ppm for long.. take that as you wish.. but starsan can last months
4) Good to know you know it can be harmed by light/heat.
All and all this is just my opinion. I posted the same poll on the greenboard and star-san is beating Iodophor by nearly double. I just wanted to see what folks use.
i use iodaphor. i've never had a sanitation issue, and it's cheap.
stains on plastic don't bother me bacause i know it's clean and sanitized.
i change out my hoses every so often any way, plus i use glass for primary and secondary, so no staining issues there.
but it's nice to have choices, right?
(plus, i like the smell. it reminds me of breweries i've been in! :p )
I use starsan. I've never tried idophor. I don't feel I can fairly compare the two.
Star-san characteristics I like
No taste, no color, seems to be very effective, keeps for a long time, no rinsing.
I don't like:
Slimy "residue" sometimes left on bottles.
Not to make more argument but I've never heard of someone getting ill from star-san, but from iodine.. yes.
I don't know if we can get either over here. :(
I use Iodophor exclusively.
I have used both, and I hate Star-san because of the foam. It takes forever to get it off (say in a glass carboy) and for the pros already mentioned in Iodophor, that seals the deal for me. I won't use anything else for my brew equipment.
