Since tools are a big part of motor vehicle repair I've run across some old hand wrenches and sockets that have rust on them and I'd like to keep them but wanted them cleaned. I was curious, due to the amount of surface rust if hand tools be cleaned with a sonic cleaner such as:

I've debated a solution of simple green, alcohol and a little water. Leave them in for a few hours or until clean but I'm unsure of any metal weakening or damaging to the finish or if it's suggested?


For surface rust and more you could make an electrolysis bath.

Easy using a wall wart or old computer laptop power block, just make sure the output is dc...

Water with a teaspoon of salt and then a couple of hours works wonders...

Best is you can use a larger plastic container as most spanners won’t fit in that sonic thing - it’s designed for small personal items ie earrings watches etc...

Baesd on comments: Do this in a well-ventilated area or put the bath outside...

The amount if chlorine released will be small based on the teaspoon of salt... see https://orbitingfrog.com/2014/11/02/electrolysis-of-water-with-pencils-and-a-9v-battery/

    I recommend soda, since salt could release chlorine gas. – sweber Dec 2 '18 at 7:38
  • You will probably get a higher concentration at the local pool... putting the bath in a well ventilated area or, better, outside... – Solar Mike Dec 2 '18 at 7:39
