1. There are some toilets that could flush by itself or automatically. But if forced manually, use a foot or a tissue to press shower.
2. That does not mean germ-free soap dispenser. Wash your hands properly and then rinse under tap water. If the faucet does not automatically use a towel or paper towels to turn off.
3. So also when doing other activities in the toilet, just use a tissue to open and close the toilet door. Later. Just throw the tissue directly. Do you carry everywhere.
