So, I have had my Atec pastry bag for a while. I always wash it immediately after finishing decorating and dry it well. Today I took it put and noticed a funny smell!! I washed it again and the weird smell is still there, any ideas what it could be???

Not sure what the smell is maybe a combination of the dish soap and buttercream? Or maybe you need to let it air dry. I wash mine then stand them up like little tee pee's in my dish drainer or on a couple layers of paper towel on the counter and leave them over night. Maybe it just needs some air. I'm not sure what is happening to yours but I know some dish soaps have these perfume smells that can linger.

Hope that was a bit helpful. Happy Baking.

Wash it in a vinegar solution then all smells will be gone
