I don't, but my guess is that it's just industrial detergent, lots of water, colour and a whiff of sodium hydroxide. It's truly unpleasant stuff. Cleans RIBs though.
Yes and no. If you look at the MSDS's then most list it as something like:
<1% Sodium Hydroxide
~15% of mixed surfactants
If you hunt around you will find a more detailed breakdown of the actual surfactants used (I have no idea if all brands of TFR use the same mix). They are quite an unusual mixture of things - so not as simple as a dash of fairy liquid and some caustic soda - although that migh well work!
Its not so expensive to make it worth mixing your own though, is it?
