They wash very easily and I have had zero problems with them rusting or with the fastening screw loosening.

I tried the adjustment screw but it does not remedy the problem.

I have even run them through the dishwasher a few times - no rust, no stains, no problems.

Never had one give me problems or break on me.

I usually buy the cheap-o ones and splurged when these were a "lightening" deal
