A quick wipe and refresh can be a baby wipe--or twelve of them. Use one on the butt or have around for old dogs and puppies who have accidents. They are a must to have for road trips, or one can use waterless shampoos and paper towels in a pinch when traveling.
Honestly, water is the best thing. Many Lab people simply swim the dog in clean water this time of year. Others use vinegar and water.
On some of my rescues or post op dogs I have used a liquid instant shampoo. On the face, I like the BioGroom Waterless Bath in the spray bottle.

Overall, my absolute favorite instant shampoo is the Self Rinse Plus from Pro Line.
ProLine Self Rinse Plus Shampoo - Cherrybrook
Put it on the dog with a spray bottle. Or wet a hand towel, apply the self rinse plus/waterless bath, rub it in, then use a big bath towel wet with warm water to "rinse" the dog. Then use another towel to dry the dog. This is good in the winter or for dogs prone to cold tail. The Self Rinse Plus is not good in the eyes, but the Biogroom is tearless, supposedly. I rinse if I can. One can even use a cup or bucket to help rinse. The Biogroom Waterless softens the coat but the ProLine Self Rinse Plus does not, a consideration for show people.
For any of these shampoos, ideally buy a separate spray bottle and cut the shampoo with water: that is an old dog show trick, and it stretches the shampoo and helps it work better.
For a yellow, one can use chalk/talc/cornstarch. It looks like bad dandruff on the blacks and chocolates, at least the way I do it. I do use chalk to clean a light dog's paws or an oily spot, then I brush it out. When traveling with Cavalier pups, I usually have a sample of cornstarch baby powder in my purse, just in case. That only helps with yellows, or really smelly dark dogs who can't get wet.
