Condiment Squeeze Bottle Sauce Squeeze Squirt Bottle for Kitchen Plastic Syrup Container Food Dispenser for Oil Ketchup Griddle Hot Sauce

Q: Can these bottles be used in a bottle warmer for hot fudge and caramel? Is it safe to warm to 145 degrees?

Don't take stupid advice, if the seller says max 100°F then don't heat them to 145°F unless you want plastic to leech into your food! Here is a little known fact: no matter what type of plastic your are working with, when it is heated it releases plastic vapors or fumes which are not safe to eat or inhale. So whenever possible do not use plastic for hot food preparation or hot food storage especially as that food approaches the boiling point of water which is 100°C (212°F) - which is usually going to be lower than the boiling point of any food that is thicker than water such as fudge or caramel. Be safe & be informed.

Q: Are these dishwasher safe? Or are they hand wash only?

I would not take a chance. Hand wash. They are excellant. I use them for my various cooking oils. Company is excellent in standing behind product. I had one bottle that would not seal right. Emailed them via Amazon link. The next day they sent a new set of 3, free of charge.

Q: does it comes with cap ?

Yes, there is a clear plastic snap-on cap

Q: Is this heat resistant??

Don’t know, I use this for laundry and dish soap. It does not drip or leak. I would not put these in the microwave because of the metal at the neck of the bottles.
