To answer your first question, a wax stain on a card should receive a qualifier. However, I've seen many Bowman cards (1951-1955) that clearly have wax stains on the back and didn't receive a qualifier. Why that is, I'm not sure.
To answer your second question, it's rather controversial these days, but my short answer is yes.
Yeah an ST qualifier. You can remove it by gently rubbing the wax stain with panty hose and no it's not detectible you won't get it back saying altered.. unless you rub a hole through the card.
Dan, the reason those Bowmans you speak of do not get a qualifier is because so many have it, that it is common. Bowmans were sold in penny packs (1 card) and all those have it and 5 cent packs of 6 and at least one of them have it too. My 52 Bowman set has prolly 50% wax stain. A seller of these cards should always mention if a card has a stain. You can rest assured that when they do not it is mentioned! Also I think that from 53 and up they do not have the stain like they do from 48 thru 52. I could be wrong but I think those are the years in question.
I have a 69 WL mantle in 5 with the slightest of wax on the back and it was given the qualifier. I have a few 52 Bowmans in 7 that do not and in the case of the Bowmans it is clearly more apparent.
One other point....The ST qualifier can mean wax stained from the factory or an olive oil stain that some clumsy collector did many years after. I wish PSA had a distinction between the two.
