A 4oz stainless prep bowl is a good brush rest. Set it in a cup of hot water and you have a brush scuttle that also works as a small, easily held lather bowl. Nominal cost at a restaurant supply or kitchen specialty store.
We keep our tap water very hot. I reach for this set up 7 or 8 times out of 10, even in summer. Warm lather, warm bristles.
