What is the best and simplest way of ghusl? What niyat and duas does one say?

We do not know the manner you were taught. To make Ghusl is very simple. Merely:

1. Pour water over your right shoulder thrice;

2. Pour water over your head thrice;

3. Pour water over your left shoulder thrice;

4. Make sure no part of the body or hair remains dry;

5. Gargle the mouth thoroughly;

6. Put water into your nose thoroughly;

7. If any impurity is on the body, make sure it is washed off;

The niyyah should be made in the heart that you are making Ghusl to cleanse yourself from impurities. There is no specific du?aa to read before or after Ghusl.

and Allah Ta'ala Knows Best
