How much product did you use? How alkaline is it? This might be a form
of "browning".  If so, a cure would be to spray an acid rinse on the
affected area.  Something like a tblspn. of citric acid added to a quart
of water, shake/stir well, and put into a hand sprayer (or you could
just wipe it on with a sponge and gloved hand).  Spray it on and observe
for a minute or two.  If it doesn't help, it won't hurt anything.  Just
don't over-wet the seat.
