I use the BKF cream, prefer it to the powder. Use it on my stainless steel sinks and hob. I noticed the price varies quite a bit depending on where you buy it, last time I bought it it was cheapest at The Range, but that was a while ago.
Reading your post reminded me I recently bought some BKF powder meaning to try it on my glass oven door. It hadn’t been cleaned since I got it 8 years ago and you couldn’t see through the brown grime to see your cooking. So I’ve just done it. I sprinkled a bit on the door and scrubbed it with the scrubbing side of my washing up sponge and the grime just came off. The whole job took 5 minutes. Amazing. Sparkling clean glass!
Love it. I use it for cleaning and polishing my vintage (charity shop) copper finds! There's nothing half so satisfying as seeing a sparkly treasure emerge from a dull old bit of tat
DD and SIL have bought a very run down house and will eventually do it up. But while they wait for planning, they are cleaning everything in sight, and someone said Barkeepers Friend was very good.
