The best way to do it is to avoid it at all, that is trying to underexposed just enough in camera for whites not to appear hot (or overexposed for that matter). Since I mostly shot at my local airport under full sunshine and with a lot of white airplanes, if I choose evaluative metering, then I compensate - 2/3; if I choose center weighted, then I keep compensation at 0.
Now, if you have already taken hot pics, then be very careful during editing not to increase this by adjusting levels on the right (=highlights) side, only left (shadows) and a bit at midtones if necessary. I don't recommend shadow/highlight tool, which in this case can be used to the contrary of highlighting shadows, that is to tone down highlights, since you can only used it in very small doses as otherwise it gives the whites a 'milky' look, very easy to spot, and worthy an editing rejection
, and it should only be used in the areas affected (sometimes difficult to select).
Also, bear in mind that adjusting contrast will have a similar effect than levels, that is if you increase contrast whites tend to go even more white.
As I said, best way to deal with this is to underexposed in camera just enough, but not too much!
