    Depends if it means:

    1% of household bleach as supplied - 10ml of the bleach in 1 litre of water

    or

    1% sodium hypochlorite - household bleach is about 5 or 6% sodium hypochlorite so for a 1% solution, about 200ml in 1 litre of water

    Precisely. If you aren't leaving the house, there's absolutely no need for hand sanitiser.

    Wash your hands often and wash down surfaces/doorknobs/etc. with dilute bleach for added peace of mind.

    Moffer if you’re any where near SE10 and not in lockdown I can supply 1 litre homebrew, for a tenner to your favourite charity. Same applies to anyone else.

    you don’t need home brew, just diluted household bleach for handles and surfaces.

    1 part bleach to 99 parts water is 1%. Or, maybe easier, a serial dilution. Take 1 part bleach to 9 parts water, measured in say cups. Mix this. This is 10%. Then take one cup of this new solution and add 9 cups of water. This is your 1%.

    It means 1% of household bleach as supplied. This is to give a solution of 1000ppm available chlorine as recommended by the NhS for decontamination of medical surfaces and as used in food manufacturing for the same purpose. It is based on the bleach supplied to food factories and the NHS being industrial bleach at 10% hypo, meaning 100,000 ppm avCl2, so 1% gives 1000 ppm AvCl2 in the final solution. This will work. If you reckon household bleach is about half as strong as industrial, then just use twice as much and make up 2% in water. It's not critical. 500ppm, 1000, 2000, they all work. Don't get it on your clothes, it may bleach them.
    2% household bleach is a coffee mug to a bucket. How easy is that? Slosh it all over, leave it to dry. This is what they do in operating theatres and meat slicing plants, post cleandown. Keep it off exposed electrical gear.

    Edit - just checked my bleach, they say use at 2% for general sanitising. That's the 200 ml coffee mug in a 2 gallon/10L bucket. It's not critical, I never measure the stuff. Close enough is close enough.

    Does anyone know the alcohol percentage of the Servisol in 1ltr tins?
    It doesn't mention it on the label and I can't find the info on their website.

    Given it is designed for spraying on circuit boards etc I assume pretty much pure. You’d not want a water content there.
