Unfortunately I won’t be using these sponges on dishes. The packaging is a bit misleading as it gives the impression the sponge has an even surface. However once hydrated, the sponge is smooth on one side, while the other side still has significant ridges from the interior of the loofah vegetable - this in addition to the stiff nature of the sponge makes it difficult to efficiently clean dishes. I have had much better experiences with other brands.
