Get a "bike bra" or just a rag to put over the top tube and head cap to stop sweat falling on them, have a few spins, leave the trainer under the stairs untouched for two years and then sell it on eBay. I think that's the standard approach.
I tried the pink high viz gilet outside the jacket trick once for a murky morning spin but luckily I caught sight of myself in the mirror on the way out and changed before I was spotted by anyone
