Question 1

What number plastic are these cups made from (what is the number on the bottom of the cup)?

Accepted Answer

I just googled SAN plastic from the description part on amazon  (Made of high-strength, break-resistant SAN plastic) 
The following is from the google search"The Most Difficult Plastics to Recycle" 
Content of this search is below:
"Plastic No. 7
This is the last category that includes “other” plastics. Products containing number 7 or numberless plastics are often made from a variety of resins. The “other” plastics include styrene acrylonitrile (SAN), acrylonitrile butadiene styrene (ABS), polycarbonate (PC) and nylon. SAN and ABS are food and drink safe, but PC is capable of producing harmful chemical compounds. Unfortunately, these mixtures make these products undesirable for recycling and forces number 7 and codeless items to go directly to the landfill. Even though recycling is out of the question, consumers can return these items to the manufacturers and reuse SAN and ABS plastics to reduce landfill waste. Along with reusing the food- and beverage-safe plastics as much as possible, you can start eliminating your need for plastics 3, 4, 5 and 7. So, be conscious of the plastic products you buy and let the plastic resin ID code guide your purchasing habits.

Question 2

Are these dishwasher safe?

Accepted Answer

Yes. They’re made for use in restaurants...they are most certainly dishwasher safe.

Question 3

Why don't they come clean i the dishwasher?  There is always some debris left behind.  We need to soak them for days before the dishwasher.

Accepted Answer

I honestly don't have that issue with mine. Wash in the dishwasher all the time. Perhaps you should contact the manufacturer. I use mine daily and haven't had that experience. Mine come out spotless.

Question 4

do they have lids like picture shows

Accepted Answer

No, they do not have lids. They are very simple, plastic "glasses". They are really small---smaller than they appear in the photo.
