I can chime in on sanitising with some experience. One hydrogen
peroxide sanitiser I have used a lot is called Perox-e. Comes as
concentrated solution which you dilute for use. Acetic acid and
hydrogen peroxide combo (can't recall the concentrations of each).

Its a very good sanitiser, food safe, and in its working dilution can
be left to dry on surfaces, without rinsing.

I am sure there are other brand names for the same type of product. I
know for sure that Bayer makes a lab/medical version.

I realise this may not be available to all, but it is a good option
if you can find it.

If i can add more things, and sound didactic, successful sanitising
really depends on getting any dirt off the surface first. Organic
material, aka crud, will reduce the effectiveness of both the
peroxide based and chlorine based sanitisers. Also exposure time is
important. Twenty minutes of sanitiser in proper concentration on a
cleaned surface will do the trick.

I've heard that hydrogen peroxide works too. I believe it was from a
