Question: How difficult are they clean? Does cake get stuck under the sweeper?
Document: I was disappointed to find that this was a pie pan with sloped sides and not a cake pan... a big difference. Seller was reticent about admitting this. I did not get what I thought I'd ordered and it did not match the description and title of product.
I remember mom using these when I was a kid. They always made our baking adventures easier with the removal of the cake. However, cleaning is no easy task as food gets between the twister and the pan and you cant get it out. I even tried to detatch it from the round of the pan so I could get under it. I got most of the food out but then it never laid down even with the pan again which of course causes your cake to tear rather than come out nicely.
Years ago I had cake pans like this after many years of use they were done. I was buying a well known cake mix ($3.00 a box) and always stuck no matter what I did. I looked in all the stores no one carried this item. So I went on amazon Yay I love these cake pan. No more sticking for me.
Noticed the complaints re: unable to clean under slicer - I use toothpicks. Cooks perfectly & the slider is simple.
These are really nice with the release knife. Helps get the cakes out & evenly. Seem to be made well
I bought tgem for me because my mom used them when i was little now my wife took them and i cant get them back
I have looked for this item at multiple sites/stores. I was so excited when I found it on Amazon. I had my niece set me up with your site and ordered it. This was supposed to be for my Mom as a gift. When it arrived, I saw a long hole in the side of one of the pans. VERY DISAPPOINTED. Won't be doing this again for awhile, too much trouble to take off work and get it back in the mail.
I was having trouble getting cakes out of my pans and my husband remembered his mom having these when he was a kid. Ended up ordering an extra set for my son who likes to bake. The releaser worked well, but, as another reviewer noted, it is hard to clean under the arm. I ended up twisting it a bit and I haven't used it since so I'm not sure if that will cause a problem in the future.
I have used these pans in the past and love them. No more sticking pieces of cake. Will order them again.
The release arms are not flat, so if you use them it tears up the bottom of the cake! I do not recommend buying these.
Answer: The sweeper moves easily, so you can clean the whole pan.  I use a vegetable brush to clean most dishes anyway, and that gets under the sweeper too.  A little bit more trouble than a plain pan, but not a big problem.
