I seem to have had a mishap. I'd noticed people in brewing videos using starsan in airlocks, seemed like a good idea so I tried it. Was really careful to not use too much in the new Plaato I've just received (around 50ml) but at one point there was a jolt as I reseated my screwtop fermenter lid. I've come back after about an hour and noticed the airlock is empty and the top of the fermenter isn't wet so it must have splashed back into the wort! So it's a 21.5L batch that now has 50ml of starsan (mixed with water which I took from my spray bottle)...Is that going to spoil or make the beer too toxic? I'm seriously concerned that my brew day has gone to waste over a dopey mistake.
