Not sure where to post this and I can't see any one ask this question maybe because I'm the only stupid one but here goes I got what I think is 304 stainless steel end cap to go on the end of my column it's got 304 stamped on the in side and shiny on the out and dull on the in side my feeling is that it's all stainless steel and when I purchased it they said it is as well I've no problem with sticking in on but I let other people drink my alcohol and I want to be certain that it's safe any help or people laughing at me for a redicolous question would be great thank

Not laughing, admiring your duty of care.
My understanding -
Stainless steel does not always shine.
My advice?
Go ahead and use it.
HTH

Robert.

And stupid questions don't really exist, well, stupid answers will always outnumber them.
You are not ridiculous nor stupid, just new.

Settle down and strap in.
It becomes better and easier from here.

Stainless shines if it is made to shine.

It is often seen as shiney because that way it harbours less bugs for the food and sanitary services it is often used in.

The inside is the cast finish. The threads are turned and this makes them shiney. Flat surfaces can polished, polished in patterns often circles (think burger van walls) or mirror finished. It also takes acid etching very well, for instructions, volumes & measures etc.

That's it really.
