The two possible reasons for stainless steel become magnetized:

  1. There was microstructural change due to the cold work and heat treatment on stainless steel, or stainless steel was exposed to magnetic metal.

  2. This is to make cookware compatible with induction cooker that heats a cooking vessel by magnetic induction.

    • Using magnet will not be able to tell the structure of stainless steel.

Definitely no, using chemical compound without proper guidance might endanger you and your property.

Daily Usage

Prior initial use, clean with warm water and mild dish soap.

If you feel the smell is unpleasant, kindly place your lid and stopper outside on a sunny day to simultaneously air them out. You may also soak the lid and stopper in mixture of water and vinegar at 10:1 ratio, and the smell will be reduced slowly.

Do not add the beverage more than maximum label, kindly leave space ½ inch from the top. Otherwise it might overspill and cause burn when you close the lid.

Cleaning the vacuumware immediately after using to prevent stains and dried-on food from building up. You can wash it with mild dish soap and scour them lightly with a scouring pad (the kind found on double-sided sponges) or wet cloth. Never use products like abrasive powder, scouring agent, bleach or dish soap contains chlorine on your pans, or scrub with steel wool that might cause scratch, damage or discoloration.

To remove difficult stains fill your vacuumware with hot water, add one teaspoon of bicarbonate of soda. Never use any bleach, steel wool, abrasive powder, scouring agent, and brightener which may cause scratch, damage, and rust. Avoid immerse the vacuumware or stainless steel lid in water, as it may rust or stain if not the gap is fully dry.

Do not immerse bottle in boiling water. It will result in deformation, water leaking or discoloration.

This is to prevent deformation or discoloration of the product.

Do not put your vacuumware in a dishwasher or dish dryer to prevent deformation, and water leaking.

It is alright for storing salty food and soup in the vacuumware, please consume within 6 hours and clean it thoroughly.

Do not store dry ice and carbonated beverage which can cause strong pressure in the vacuumware. It may result stopper to eject forcefully.

Do not store acidic beverage such as plum juice and lemon juice etc., which may lead to poor performance in hot retention.

Milk, or dairy product and fruit juice should not be kept in the vacuumware for prolonged period as it may spoil.

Yes, but it is not advisable because the design of stopper are not suitable for hot drink and can’t last longer if compare with other same capacity Thermos® products. Be caution when the contents are hot, do not drink directly from the product.

Not all vacuumware products can use for thermal cooking. For thermal cooking, you need to boil and simmer all ingredients until reaching same boiling temperature; the food keeps cooking slowly in its own retained heat in the vacuum insulated pot that has vacuum-insulated double walls. Food must be at least ¾ full and reach boiling temperature in order to cook thermally.

  1. Please prepare a 470ml (or above) vacuumware.

  2. Put all ingredients into the vacuumware and pour in boiling water until three quarter full. Close the lid and preheat the vacuumware completely and then drain the water.

  3. Cooking time for congee, noodle and hard boil egg are 90 minutes, 7 minutes and 20 minutes respectively.

When hot drink or food has been put into vacuumware, the pressure automatically developed and you find yourself unable to unscrew the lid. No worry, it is normal. Running the lid under hot water for a minute will make it comes off more easily.

You may replace parts like O-ring, stopper or lid follow original position and direction. It is not advisable to assemble or repair other parts because it may cause scratch or damage on the product.

Pulling strap with force might cause damage to the sling pouch.

Maintenance and Cleaning

The vacuum insulation is no longer working when the product is being hit/ strike and the unit is irreparable.

Please contact and purchase replacement parts from customer service.

Partial peeling off might be cause by frequent contact with high heat or oil (such as hand cream) which may soften the coating.

Try this test:
Add hot water into the container
Wait for few minutes
Touch the outer surface of body
If it is hot, vacuum insulation is not working.

The desiccants in the vacuum insulated chamber are used to absorb moisture. Desiccants are used to extend the life of vacuumware by absorbing unwanted gases and moisture that promote heat transfer within the evacuated space. Normally desiccants will reach saturation after 5 years and decrease the heat retention performance.

Vacuum insulation is not repairable.

Vacuum insulation function is not able to be recovered once it is not working.
