See-through

I bought some Astonish oven cleaner some time after I bought and used the Astonish cup cleaner. I finally got round to using it this afternoon on the glass from the oven door, which has not been see-through for some time.

I applied some of the cleaner with a black scouring sponge to the glass. It took a while, but now the glass is like new. Astonishing.
