My Kitchen Cook & Bake 25cm Loose-Based Deep Cake Tin

I bought this tin confidently as Lakeland goods are great quality. Not at all disappointed, very heavy gauge tin, perfect for frequent use, non stick means the cakes slip out perfectly. No need to use a liner, just a quick spray of bake easy.& a circle of parchment in the bottom. However, my one grouch is that the groove on the base makes it incredibly difficult to clean, even after a washing up brush & a toothpick, I'm not confident of removing the bits of cake.
