I have a Waring Pro meat grinder and the instructions also state that the parts are not dishwasher safe. 


I called the company and asked why. I was told that basically what the dishwasher does (because of the chemicals in the soap, and the heat) is discolour the metal, and in some instances can cause flaking of the finish. The discolouration itself is not an issue as far as safety is concerned, but if you get the finish starting to flake and come off, you wouldn't want that in your food. It isn't necessarily harmful, but it doesn't look very appetizing.

I have an idea here.


After giving it some thought, I think the best way to do this would be to hand wash the parts in the sink with hot soapy water and then stick 'em in the dishwasher with out soap and do a high heat rinse.


This way you could do a proper hand wash and get rid of all the nasty bits, and then do a final sanitizing rinse in the dishwasher, with out the risk of the soap doing nasty things to the finish.


What do you think?

Anyone have any resources to fix the pollished aluminum oxidation as mentioned above? I was an idiot and on my second run with the Cabelas Pro Grinder, put the hopper in the dishwasher. It came out looking terrible and grey dust everywhere on it. Can this be restored somehow? I already placed a call to Cabela's to see if I can get a replacement. Still waiting there.

Oxidation it self wont cause health concerns but other terms for oxidation is rust and corrosion. Oxidation also kills flavor and aroma in food and drink. Think open bottle of wine the next day.

Bleach is never a good idea for metals. Bleach will eat pits in stainless steel which leaves you with an nice conversation piece for the coffee table. I use  a iodophor sanitizer called BTF. use it in a 25 ppm solution with it being safe for any surfaces. It will not stain in a diluted solution but dont get careless with it undiluted. Iodophors are used Extensively in the food handling and restaurant industries. it is accepted by, maybe not all, but  by health 

Authorities  as a non rinse sanitizer in a 25 ppm solution. I pay 11 bucks for a half of liter and will last forever. I buy mine at my local home brew supply store and I know that there are on line home brew supply retailers that offer BTF or other Iodophors for sale.

That powder stuff is “bauxite” (pronounced Boxsite) it is aluminum hydroxides, which is the principal ore of aluminum. No matter what you do, eventually aluminum is going to return to its natural state which is powder. I wash my machine down with 10% bleach water and soap solution (by hand ),  I allow it to dry on a towel on the table for a day or two, then I will give it a give it a light coat of food grade spray oil (I think it is mineral oil)  before I put it up in one of those plastic tube form Wal-Mart. Usually you will see Boxsite if there is a presence of moisture or salt. Even though you may washed and dried it, there may be moisture in the pores of the metal. Maybe it is the humidity in the area of where you live doing it. It may just be me, but I think drying it in the dishwasher would get it warm enough to get all the moisture out of the pores. I have had a spot or two on pots in the past and I used a Scotch bright pad on it until I removed any problems. Hope this helps. SB

Bleach ( Sodium Hypochlorite ) Is the only chemical that will pit Stainless Steel. Believe it or not it will rust Stainless Steel. I ran a milk processing machine once for a while and Bleach was not allowed in the lab as a cleaner on Stainless. Most dishwashing detergents contain Sodium Silacate or Bleach. The magic word is Sodium. Keep Alum, Pewter, copper, cast and Stainless pots and such away from anything that contains Sodium, Or Citric Acid ( Lemons, Limes, Grapefruits)
