I know you've already gone but for next time you can try what we called an irish man's bath. Get a small towel, twist it into a cord than wrap the cord into a flat knot - you need to get it really tightly wond sort of into a curry comb type thing (great description I know). You need a bucket of water as hot as you can stand to touch. Start with a well brushed horse and cover him with a cooler. Dip your towel in the water so it is damp, uncover a section of horse and use the towel like a curry. Recover the section, redamp the towel and do another section, you'll have to retwist the rag a few times as a section gets dirty. By the time you are done the horse should be dry where you started, relay the coat with a brush and your're good to go. You need really hot water and the rag needs to be twisted tight enough too feel hard, otherwise the horse gets to wet. This obviously dates me to before miracle groom and dry shampoos became popular, or makes me too cheap to buy them - take your pick. I also hate show sheen etc for anything other than tails.
