Hi Michael,
I have been doing my own for the last couple of years.
The main thing is to identify the controls on your pump and filter.
Empty the pool with the control on Rinse.
When empty clear all the debris and then clean all the pool with a simple detergent hosing down as you go.(the wife can do this).
What I do afterwards is get a few bottles of domestic bleach, squidgy bottles are best and then squirt this all over scrubbing with a brush as you go, this cleans the grout.
Rinse off well and then start filling your pool, easy innit.
