one step is incredibly good for home brewing. Keep in mind sterilization isn't a practicable option for home brewing so we use sanitizing which is an industry thing. Oxy is very powerful and cleaning and destroying cell walls and thus getting rid of organic matter (and getting your shirts bright white). For decades all I used was one step with never a single issue. Use hot water.
My current routine is to primarily use one step on everything, I make a small batch of star san in a spray bottle for targeting stuff like spigots, tubes and I give a quick spray to the insides of my fermenter and keg.
