Coffee grinder sheet


#1

Trying to get these sheet metal screens cleaned for a local coffee company. They have a couple years of build up on them from the beans. I’m kinda iffy on putting a heavy cleaner on it. Anyone have any ideas?!

Never underestimate the power of a stiff brush.


#3

I would try soaking in either straight or 50/50 white vinegar & water. Works to clean small coffee pots and percolators.

Would need a rather wide basin to submerse them in, though.

Bar keepers friend should do it.

Here’s a starting point

According to that article these are allowed:
• Chlorine Materials (see notes below)
• Hydrogen peroxide
• Ozone
• Peracetic acid/peroxyacetic acid
• Phosphoric acid
• Potassium hydroxide
• Sodium hydroxide

And
• Acetic acid
• Ethyl alcohol
• Isopropyl alcohol
• Citric products/limonene
• Potassium permanganate
• Sulfuric acid
• Vinegar
• Quaternary ammonia

But you must rinse really well

I use sodium percarbonate at home in my coffee pot. No brushing at all. All the impossible brown stains float right off.

I’m not following… haha.
