Smells definitely take me back, the one instance I recall is one xmas when I was just kind of growing up a bit (11ish) I got a present of some perfume , and a ladybird-shaped hairbrush, the perfume isn't around any longer but whatever scents it was comprised of still remind me of xmas-they crop up every now and again.
Germoline reminds me of school definitely-although I'm not sure It's the scent or the sight/presence of the product. I hate the stuff
