I know that the numbers (usually 3-4 digits) enclosed in a red diamond on the back and sides of truck tanks indicate exactly what liquid is inside. Does anybody know where I can find a listing of these numbers and what they stand for?

Twizz1234 asked:


The other day, I cleaned my diamond (the stone part only) with a tiny dab of toothpaste, very gently with a toothbrush. It worked extremely well. However, I have seen about 15% of the websites over the internet saying that toothpaste should not be used since it is too abrasive.

A) Isnt a diamond one of the hardest substances found in nature? If so, then how can toothpaste scratch it? The average person brushes their teeth (2 times a day x 365 days a year x 60 years =) 43,800 times with toothpaste! If it was so abrasive, would we even have teeth left after that much brushing?

B) Someone said toothpaste works by leaving a film over your teeth to protect it. I find that really weird. I usually brush my tongue every morning and I have never noticed any film accumulating on it. Does anyone think that it is true?

Thanks for your help.

If you wonder what I’m talking about see amnestyusa.org/diamonds. It’s pretty scary how much control companies have and how many diamonds fund terrorist groups so they can keep the supply down and the cost up.
