Any rider who has spent long hours in the saddle day after day has probably at some point had the misfortune to experience a saddle sore. That felling that starts with a mild irritation at the end of a ride, only to wake up the next day to a full on saddle sore and a world of hurt. At this point there is not a lot to be done, other than suffer. Although I once watched a documentary on the Tour in the days of David Miller, where they would take raw meat (usually Liver) and seal it in a ziplock bag to then be placed in their shorts over said irritated spot. Apparently it worked, but rumors of the team chief then cooking it and making the “Lantern Rouge” eat it for dinner are apparently not true. One method of prevention I was introduced to when racing in my teens was the wonders of “Savlon”. Or ironically our knick name for it now used in other cycling circles was “Ass Saver”. Savlon is a British made antiseptic cream. The stuff that when you were a kid and grazed your knee was the go to “magic cream” that your mother used. For this particular use case, usually after a post ride shower and drying, I put a thin layer around any contact points that might need a little love and attention (or even if the don’t to be preventative). I have got to the point where I do this after every ride and have not had a saddle sore for nearly 20 years. Is it the Savlon? Maybe, but that is the magic. Something is working and I am not changing it. So my recommendation would be, like me, if you are ever flying through Heathrow make sure you make a visit to Boots Pharmacy (they are in every terminal) and pick up a few packets. It is always something I keep in my kit bag.
