This is another revisit in wudhu’.
Narrated Humran, the manumitted slave of Uthman,
Uthman b. ‘Affan called for ablution water and this is how he performed the ablution. He washed his hands thrice. He then rinsed his mouth and cleaned his nose with water (three times). He then washed his face three times, then washed his right arm up to the elbow three times, then washed his left arm like that, then wiped his head; then washed his right foot up to the ankle three times, then washed his left foot like that, and then said: I saw the Messenger of Allah (may peace be upon him) perform ablution like this ablution of mine. Then the Messenger of Allah (may peace be upon him) said: He who performs ablution like this ablution of mine and then stood up (for prayer) and offered two rak’ahs of prayer without allowing his thoughts to be distracted, all his previous sins are expiated. Ibn Shihab said: Our scholars remarked: This is the most complete of the ablutions performed for prayer.
you must have the intention IN YOUR HEART that you want to perform ablution. Wudhu’ without niyah is invalid. An invalid wudhu’, will render the solah not acepted as well. Allah knows best.
Here is a link by Islam QA on when to make the intention of wudhu’.
2. Saying Bismillah
There are different opinion in whether saying Bismillah is obligatory in wudhu’ or not. Some say it is mustahab and some say it is fardh. But we will say the Bismillah anyway. Insya Allah khayr.
Another link of fatwa collected by Islam QA concerning saying Bismillah in the toilet when we take wudhu’.
3. Closing sequence or tartib.
Meaning when we perform ablution, you must follow the order. We cannot just do any part of wudhu’ in random. It has to follow the order.
And also if we missed a part of wudhu’, we must repeat the wudhu’ all over again.
Hadith recorded by Abu Dawood from Khalid Ibn Ma’daan (may Allah’s Mercy be upon him) from some of the Prophet’s (Sallallahu Alaihi wa Sallam) wives that the Prophet (Sallallahu Alaihi wa Sallam) saw a man praying and a small spot of his foot not washed, so he ordered him (the man) to reperform the Wudu.
