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.
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
• Peracetic acid/peroxyacetic acid
• Phosphoric acid
• Potassium hydroxide
• Sodium hydroxide
• Acetic acid
• Ethyl alcohol
• Isopropyl alcohol
• Citric products/limonene
• Potassium permanganate
• Sulfuric acid
• 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.
Its a cleaning product. Google it
