Like what someone said in this thread, might not even be the steel, it might be the plastic parts.

I also find it scary that some people use plastic Tupperware put into microwave

Even though the label say microwave safe,

I still find glass Tupperware is safer.

Research in youtube, this news is actually 5 years ago unless there was another new case with exact same diagnosis also died after 1 year.

Story was everyday brought coffee in vacuum flask to work for 20 years. Used metal bristles brush to clean the inside. Drove car crashed into breakfast shop then diagnosed of lead poisoning. Died 1 year later due to choking leading to aspiration pneumonia.

Coffee is also acidic.

For old people in the article they not likely to drink fruit juice

But more likely coffee
Read an article that china consumer group tested stainless bottle. Need to boil 5% concentration acid for 30 minutes then left inside the bottle for 24 hours then the leached metal exceeded safe limit.

Most vinegar sold in supermarket is about 5-6% concentrate. Most people cannot drink this concentration directly, will chemical burn mouth and throat lining with just one sip. So unless the acidic drinks beverage is as acidity as vinegar, is safe to keep inside stainless steel vacuum flask for few hours.

yeah, but it is a 1 time 24hours test with concentrated acid mah.

we are talking about years of using the SS bottle to store light acidic drinks like coffee/ fruit juice.
thats why to play safe, buy reputable brands and change bottle every couple of years

Stainless steel will form new protective chromium oxide layer instantly when the existing provective layer is removed.

Stainless steel has simi protective layer??

Stainless steel is a composite metal. Stainless steel composition varies by grade, but all stainless steels contain at least 10.5% chromium, which is essential for their corrosion resistance. Common alloying elements include nickel, molybdenum, manganese, and silicon. The most common grade, 304, typically contains 18% chromium and 8% nickel, while 316 adds 2% molybdenum for increased corrosion resistance

304 Stainless Steel:
18% Chromium, 8% Nickel, 0.08% Carbon, 2% Manganese, 0.75% Silicon, 0.045% Phosphorus, 0.03% Sulfur

316 Stainless Steel:
16-18% Chromium, 10-14% Nickel, 2-3% Molybdenum, up to 2% Manganese, up to 0.75% Silicon, up to 0.10% Nitrogen, up to 0.08% Carbon, up to 0.045% Phosphorus, up to 0.03% Sulfur

310 Stainless Steel:
23-27% Chromium, 0-1% Manganese, 0.01-0.08% Carbon

I don’t think there should be an issue, if it is real and good quality SS.

If need to throw…then are we expecting Hotels and all F&B companies to change their tools after 5 or 10 years????? :ROFLMAO:

Then why nobody ask Singapore Food Agency for advice?
