As last Sunday was so lovely I spent the afternoon cleaning my mini greenhouse. I had a lot of water staining on the glass from the irrigation system. I tried MAAS metal polish as it was recommended for glass, but it which took a lot of elbow grease and still left marks. So I thought I'd try the Kilrock spray and a fuzzy nylon panscourer that I use on the sink. Wow! It really shifts limescale with very little scrubbing needed.
I just wish it was as easy to get my plot dug...
