Reference No: 14541840
Thank you for your email regarding Cillit Bang
We would not recommend the use of Cillit Bang for preparing steel sheet or tubing before brazing or soldering, as it has not been tested for this use.
I'm sure that's from their legal department rather than their technical department. So there recommendation is not to use something without testing it first, a sensible suggestion, I'll have to think up some appropriate tests.
Apart from Aggy and Kim, it would appear that there's some other cleaning experts out there. The Toxics Use Reduction Institute have a database of cleaning solutions.

There's also a useful book in the Workshop Practice Series, called Tool and Cutter Sharpening which describes lots of different grinders and some instructions for building your own jigs.
And you can also buy part kits for Quorn, Kennet and Worden grinders.

I've also been thinking about how to sharpen my new lathe tools (to be delivered shortly), a bench grinder is the obvious choice but there are so many different kinds and prices for them, ranging from a B&Q special at £10 to the "Creusen DS9300 Industrial Grinder" from Axminster Power Tools which comes in at £819 (partly I expect because it's 3 phase). I've delegated this job to my Dad as he's bought and used more bench grinders than I've had hot dinners.

However, since then I've been reading some books about materials including Workshop Materials(Workshop Practice) by Alex Weiss and have been thinking about pickling, that's pickling of metal, not pickling of cucumbers. The idea is that you need to get all of the oxide and grease off your metal before you do things like plating or brazing or welding.
So there is some possibility of Cillit Bang working for this process. The description from the FAQ on the website is that it contains a mixture of acids and surfactants, so I've dropped them a note asking what they think about this idea.

Choose lathe... But why would I want to do a thing like that?
With thanks to Irvine Walsh for inspiration for this poem.
