Are you baking things directly on the wire rack? I don't have a Breville, but when I heat up anything other than toast I use the tray that came with my Cuisinart and line it with foil. That keeps the crumb tray clean.

Even with foil, the tray itself eventually gets stained; I use steel wool to clean it. Yes, it scratches, but I'd rather see scratches than baked-on grease.

I have the Breville and I always use foil. I get the non stick one. The crumbs etc. slide right off it.

You can purchase non-stick liners for toaster and regular ovens. Silpat makes some but there are other companies. I just looked on Amazon but probably places like Target etc. would also sell something similar.

I would remove the pad completely occasionally.

It's only when using the toaster function that the spills happen. I make garlic toast often with olive oil on the bread and that's mostly where the spills are coming from, sometimes from butter, etc. When I bake I use the baking tray that came with the toaster. I've looked it up about not using the foil, evidently a fire can easily start with using foil in the crumb tray, didn't know it back when I did it with the other one. I'll have to look for the item that you are referring to, maifleur. Do Silpat items take high temps? I've never used any of them.

Mine never bakes on and yes, I get cheese drips all the time. They slid right off.

I don't use a toaster oven but have used a Silpat liner (Bed, Bath and Beyond) in my oven since years. It has not problems with being heated to 450 degr, don't know about higher than that since I don't use the grill.

I have a breville toaster oven. I just pull the tray out, dust off the crumbs and wash it if it needs it. Why line it with foil? I guess if something might spill,over, I could put foil on the lower rack.

ritaweeda from the silpat site since it is being marketed by them for toaster ovens I am making an assumption that they take high temperatures. https://silpat.com/products/silpat-toaster-1?_pos=1&_sid=75affd683&_ss=r
