Here's a tip- if the icing gets too thick, and hard to come out, just sit it in a coffee cup of warm water

either because while washing with hot water they felt like they were gonna melt in my hands.

I've been warming up sauces in the other bottle by dipping them in hot water and basically babying it

Just put in some hot water to clean

Washing was easy, just filled with hot soapy water, shook, and emptied.

All I did was wash the top with warm water and it came perfectly clean

As soon as I unpacked these bottles, I filled one with warm soapy water and attempted to clean the cap by gently squeezing the soapy water out.

Worked great, kept the chocolate warm enough, and did not melt when I placed them into a pot of hot water in the stove to reheat

They will leak any thin liquid (water, olive oil were my tests)

You will need a bottle brush to thoroughly scrub both bottle and top, however soapy hot water should be good enough.

If any hot water makes it in, it makes whatever is inside taste like plastic.

You can't microwave them so you have to heat the bottles in warm water (but not too hot or you'll melt the plastic).

I tried dipping one in hot water and it came apart at the seams

If you need to keep them warm, just sent them in a pot of warm water, and your chocolate or caramel will stay nice and smooth.

They are a little hard to clean, but if you soak them in warm water for a little bit it makes it easier

Work as they should.
