You need oil and lots of water in hot climes so you should have quality soap with oil built in or just rub olive oil or castor oil in your beard leave an hour or all night preferably with a big towel around your pillows - come morning - soft as anything and a doddle to tame.Some shave prep can help. That Cremo you have been using could be good for prep. Mix just a little of that with warm water and apply on the beard, let it soak for a few minutes and rinse off.
How do you moisturize with oil? Isn't it water that provides moisture? More traditional style barber shaving prep uses warm water with a bit of soap or cream. The water needs a few minutes to soak into the hair to soften it.
You want oils that traps the moisture - hygroscopic like the two above - sorts your skin out too.
