Clean Aluminum: 

Wheels: Rims must be made of aluminum. Steel rims are
considered short steel. The wheel weights and valve stems
must be removed to receive full purchase value (Weights may also be
purchased separately at current market value). Wheels with
plastic coating or chrome will be purchase as dirty even if the
wheel weights and valve stems have been removed.

Old: Clean aluminum sheet. Includes any type of aluminum sheet with small amounts 
of contamination such as screws, staples, light tar, caulk, etc. Non-returnable pop 
cans are also purchased as Old Aluminum as well as other aluminum cans such 
as cat food. Pontoons are purchased as Old - BUT THEY MUST HAVE A HOLE 
CUT IN THEM so we can see that there is no foam, water, etc. inside.

Painted: Includes siding, soffit, facia and other similar materials. For the most part, any 
sheet-type aluminum that has been FACTORY (not hand) painted. All screws 
and backing material must be removed to receive full purchase value.

Cast: Cast Aluminum such as BBQ grill covers, aluminum heads.

Clip: Good, clean and shiny aluminum like lawn chair frames.

Extruded: Window and door frames. Material has been run through an "extruder", it has been 
"molded not folded".
