The three things most people would say contribute most to a successful brew are cleanliness, temperature control, and time/patience so this is a good place to start.
I would say scrap all non-organic bleaches. Wash (you can use Fairy liquid) and rinse everything thoroughly, then sterilise with a “no rinse” steriliser like sodium percarbonate - don’t be tempted to make a stronger mix thinking this will be better, it isn’t.
Make sure you control the temperature of the mash, that you pitch the yeast at the right temperature, and that you ferment at the right temperature, ideally for two weeks. When you bottle, leave the bottle somewhere around 20C for at least two weeks then store somewhere cool for another month before you drink it.
