My cleaning method for everything white is using these products and with the liquid detergent. For the white towels I would add all the the products listed and when the rinsing cycle on the washing machine starts I'll add white vinegar (where you would normally add your softener) this method keeps my towels from becoming hard, so they stay soft for long.
For stains I add, bicarbonate of soda, a drop of liquid soap, a few drops of essential oils and water into a spray bottle, spray it onto the stain and after a 30min or so I'll wash it in the washing machine. This can also be sprayed onto your mattress for that special effect.
