I just looked up these bowls on the Basis Pet web site. Wow – those are some pretty pricey bowls! $28 for one large bowl?
The picture looks like it has a brushed finished. I think that the only thing that would surface clean it would be a Mr. Clean Magic Eraser. But, I don’t know what’s in those things (they clean my tennis shoes WAY too easily) and I’m also a little paranoid when it comes to my dog’s food bowls, so I would toss the bowl into the dishwasher anyway.
I buy mine at restaurant supply houses. They have a shiny finish and are the same stainless steel composition as the Basis Pet bowls. I found a comparable large bowl on-line at about $1.50 each. If you want a non-sliding bottom, one of those would be about $4.50 each. https://www.webstaurantstore.com/3-q...l/407MXB3.html https://www.webstaurantstore.com/3-q...e/922MB03.html
I feed raw, so my dogs get a fresh, dishwasher cleaned bowl every day. Restaurant supply houses will bulk sell in minimum lots of six for a unit discount.
I don’t like the flange design of the Basis Pet food bowl. That little rolled lip will collect water after dishwashing. You can find restaurant mixing bowls that do not have that lip.
The Basis Pet food bowls are made with 22 gauge stainless steel vs. the 26 gauge for the restaurant bowls, so they would be a little heavier for the exact same size bowl. And I couldn’t find if the restaurant mixing bowls are made in USA or not. But, given your dissatisfaction, I would send the bowls back and see if you could find a local restaurant supply house. They can provide you Country of Origin information and you would also be supporting a local business!
