Is Starsan effective against yeast?
After resuming homebrewing again after a 2 year break, I started having pellicle appearing on my starters (after fermentation had completed), which has now spread to my plastic fermenting buckets so that the last 3 batches have been contaminated ("infected") - looking similar to this. The beer tastes fine, maybe slightly sour-sweaty. I plan to clean and sanitize all my equipment that's used post boil. I normally use Starsan to sanitize, but clearly the wild yeast are not affected. The made up starsan reads 2.8-3.0 on the pH meter.
Would iodophor or bleach be a better solution to get rid of this unwanted visitor?
