Milk & yogurt have been known to neutralize some smells. A GF I had long ago from Singapore said they soak fish in milk before seasoning and baking it to remove excess "fishy" smell.
There is an Old Wives Tale about swallowing Milk or Yogurt right after Onions or Garlic to reduce the smell coming from the stomach. I've never tried the technique exactly, but I have noticed that when combining milk with O &G, it significantly reduces the smell coming out from the pores and perspiration. ( I discovered this while using an obscure home remedy to relieve fever & congestion and boost immunity: Quartering 1/2 Onion & 4 cloves of Garlic and steeping it 6 hours in liquid Honey and fresh lemon juice - then eat it all, and wash down immediately with hot milk! )
