Anti-misting Liquid For Windows And Mirrors

[geaneous]

Many years ago ( probably 20+ ) I used to be able to buy a liquid in a small bottle that one applied to a mirror or window, that stopped them from misting up due to condensation etc.
The liquid was applied to a cloth and the cloth was stored in a screw top jar to prevent it from drying out.
Once applied to a mirror or window pane , it prevented misting for a few weeks before needing to be re-applied.
Due to the mirrors in my bathroom constantly misting up , I would be grateful if somebody could provide me with a product name or better still the name of a stockist this material.
I have tried opening the windows to clear the misting-up but it does not work.
Thanks in anticipation of a positive outcome to this problem.

(though I'd try a little vinegar diluted in water before buying anything)

We bought a jar which sounds exactly like what you are talking about. I think it was called Twenty-Twenty Glass Demister althought I can't find anything on the web to back that up. (I think it had a Union Jack somewhere on the lid or label).

Halfords use to sell it for car-windows

I use the smallest amount of shampoo (literally talking about a dab) on a cloth and keep rubbing it on the mirror until smear and streak free, obviously this would take a lot longer if you wanted to do the windows as well.

You used to be able to buy a little tub of pink goopy stuff called Mista Bright, used for specs, mirrors and windows - anyone remember that?
