I've never used any sanitizer or soap/bleach on my fermenter or bottles. After I bottle a brew I take my fermenter outside and hose it down while using a soft sponge to get any of the thick stuff off, I don't use a scourer as to avoid any scratches that may become areas at risk of infection.
After it's spotless I pour in about 2-3 litres of boiling water, fit the lid and give it a good shake, being sure not to spray myself with water that may come through the airlock hole. The steam and boiling water will kill any and all bacteria in the fermenter. I can't comment on others vessels but the high temps have not damaged my plastic fermenter, which was my only concern when trying this method.
