Soak the washcloth in as hot a water as you can take and apply it to your whiskers for 5 to 10 seconds. Wrap the small bar of hotel soap in the washcloth and soak it again in hot water for 10 seconds, then rub it on your face/whiskers. A thin film of soap will cover your whiskers.
Step2
Shave.
Step3
Wipe you face clean of any soapy residue. Done!
Tips & Warnings
You'll probably feel like you got a better shave than you ever did with a can of lather, gel, or any other shaving cream including a brush and soap like I use at home.
Don't apply hot water any hotter than you can comfortably tolerate.
