bleach virgin - how to dilute for use in spray bottle?

[MousyMouse]

as title says.
main thing to clean are tiles/mouldy grout and mould aroud the window vents.

also would bleach whiten a loo seat that has become a little yellow?

I'd do 1/4 bleach to 3/4 water. Thin bleach. The value stuff. Add a few drops of washing up liquid once you've made up the mixture (not before as it will foam up too much). I don't think it will do much for your toilet seat though.

thanks.

would thick bleach work as well?

do you spray on and wipe off or leave?

sorry for the questions, I'm usually in the hot-soapy-water and cloth camp.

I don't think bleach will save a stained plastic seat to be honest. For mould i'd recommend Harpic powerplus. My sister's bathroom is poorly ventilated so she squirts harpic onto the grouting and along tiles. It has a limescale disolving formula where as bleach will just hide discolour the grime so its actually not been budged with bleach. I know harpic is a loo cleaner but as long as you rinse it off properly its fine to use elsewhere.

Thick bleach doesn't mix as well and may foam. I use the stuff in the giant bottle. I spray and leave, but only use on white things. And am lazy.

I now used the thick bleach (found it in a cupboard in the new house) neat on the mould stains in the shower and it worked a treat.
for the rest I think I will just use my trusted hot soapy water.
