How often do you get through a bottle of hand wash?

[Sparksi]

Just being nosey. I feel as though I’m replacing the 500ml bottles every few weeks and it’s just me and DH.

No, we use the shower gel that we get at Christmas that isn't the one we like.

that we use as wool detergent (if we like the scent)

I live alone and have five sinks ( which has shocked me😂).

I have to replace one every six months or so.
