Rust spots? S35VN Umnum

[DBH]

Wipe it down, use an eraser, then alcohol or another light oil and wipe it off. I use mine in a somewhat wet environment and the pepper spots disappear. No big deal to me.

Flitz, I get them on many of my EDCs this time of year.

I opened a can of drain cleaner . The seal on bottle was stubborn and i used my small sebenza to cut it .
I noticed a dark spot on the tip . Not rust but a stain that was very hard to remove! Drain cleaner is a strong acid i believe. Many foods contain acids.

Drain cleaner is usually sodium hydroxide (strong base) and sodium hypochlorite (oxidizer) both of which are corrosive, particularly the hypochlorite in this case.

Thank you Don m for the correction
