Oh, ya, I can see this being really nice for the kitchen sink or the stand in shower. Right now, oil build up gets trapped in corners that require a brush to work out, which is tricky in the shower where it’s all calked.
It feels like the more things I use a kitchen sink for the more I appreciate corners. Cleaning is a little more involved but being able to e.g. set two buckets next to each other and have them be level is really really handy.
