This question has nothing to do with electronics directly, but...

How can I remove ferric chloride stains from clothing? I've wrecked my favourite pair of trousers!

Join the crowd. You have now been fully initiated into the ranks of PCB etchers! Without the stain, you would have been treated as nothing more than a dabbler in electronics.

Seriously, I've not been using ferric chloride for so long that there are a lot of products that have come on the market that may (or may not) take care of the stain. Back as late as 1985, an etchant stain like that was permanent. Today, although I've not had to try them, there are products designed for bathroom iron and calcium stains that may work. In the U.S. products such as "CLR" (calcium-lime-rust) have appeared. And lately, the Oxyclean-type products have come on the market, but I think they're more for organic stains, although Oxyclean did rip out every spot of a new lab coat that was majorly splashed with Betadine solution.

"Test product on an obscure area of fabric to determine compatibility before use."

'You have now been fully initiated into the ranks of PCB etchers!' At least the stains have had their use!

Seriously though, I once upset a tray full of etchant on my desk. The wall, desktop lamp, keyboard, speakers and PC have had their share! I'll have a look at some cleaners, becuase I really mourn my trousers! I went to Maplin's the other day to restock on etchant and found they sell another type of etchant in powder form that's meant to be safer and it's a colourless solution as well. You won't catch me using ferric chloride again!

Lemon juice?!! I'll go try that now!

The good thing about ferric chloride is that you can see where you spill it.

I've just come to live with the fact that I have yellow spots on all my clothes... check trousers... yep.

I have some special white powder (no, not that sort!) that I bought from Mega Electronics, which claims to remove ferric chloride stains. At the time I thought it would be worth it, because I'd got a few stains on things I didn't want stained. As it was, I got more careful with the ferric and did less etching, so I've never actually used it. :-/

The lemon juice tip sounds worth a go though, the next time I have a spillage.

BTW you can do a quote using

backslashquote{ your quote here }


quote:

I really mourn my trousers!
(The above was quote and I can't get the system to quit adding all sorts of brackets on its own nor will it take any form of "backslashquote" that I can come up with.)

I'd more mourn some of the things IN my trousers with regard to what ferric chloride might do to them as it soaked through!

Lemon juice! See, I told you there were some new products out there that might work!

So, Alan, how about a bit more detailed information in real-text about how to do the quote thing for this slow, old lummox?

Take a tip from someone who's been using ferric for 30 years - just live with being pie-bald and stop moaning

There is a lot of advice in the formatting guide in the Help section, or here http://www.chatzones.co.uk/cgi-bin/discus/discus.cgi?pg=formatting


  • Copy the bit you want to quote, to the clipboard.
  • Type a backslash followed by the word "quote" without the quotemarks,
  • followed by a left brace (curly bracket),
  • paste in from the clipboard, then
  • type a right curly bracket


It also does bullet points

A big stain and a few drops of lemon juice could produce a "happy face" on your pants that will never go away. Now what? That's all you need is a face in your crotch staring at folks as you toodle down the sidewalk!

The remedy I've read about is 100ml of acetic acid (or strongest vinegar you can find) and 100g of common salt, so maybe try that.

One side effect is that it makes you smell like the apron of a fish and chip shop proprietor.

The salt and vinegar mix is also the standard for making copper shiny.
