I got acid on my fingers and I think on my lips

My dad bought special acid to pour down your toilet drain to help clean clogs or something.. and he asked me to pour one cupful down mine..

I was so careful and afterwards he said make sure you wash your hands real good.. I go back into the bathroom and turn on the lights and my fingers are burning and I have white spots on them... My lip feels like its cut open...



Oh yeah - I just had to have a damn pretzel before I washed my hands.. I think thats how it got on my lips.
