Hello, I was wondering if someone knew what product/chemical could turn the clear Dettol antibacterial spray fluorescent yellow. I sprayed some Dettol onto a bit of kitchen towel and wiped my tap with it and the Dettol on the kitchen towel instantly turned fluorescent yellow. I tried it again a few minutes later but it didn't do it again. Clearly there must have been something on the tap that either was fluorescent yellow (I really doubt it...) or something that reacted with the Dettol. But what could it have been? Any ideas?
