Bath cloths. You heat it up in the microwave and it really makes you feel clean. I used to cool down while gathering my hygiene supplies for the bathroom while it heated up. I would wash my face and re-wet/gel my hair with my regular products and then clean off just the sweaty areas with the bath cloth. They are like baby wipes in texture, but bigger. They cost more, so occasionally I would just use a towel and regular soap. Then I would put my make up on and run a brush through my hair. I showered before riding to work, but my route was hilly, so I sweat, despite cool temperatures and not riding that fast.
