Hallo, ich habe noch altes, angebrochenes Moersch Easylith. Lösung A ist dunkelbraun gefärbt. Ist es noch verwendbar? Ich erinnere mich nicht mehr an die Fa...

Hello, I still have some old, partially used Moersch Easylith. Solution A has turned dark brown. Is it still usable? I can’t remember what colour the fresh solution was... Thanks for your replies, Andreas

Hello Andreas, Neither the age of the solution nor a low liquid level should cause Solution A to discolour. At the very least, ‘browning’ should be ruled out within four to five years if the liquid level is still above the width of a thumb. The solution must be virtually colourless. So one of us must have done something wrong. Can we rule out any contaminants in the solution? Even mixing up the lids could cause solution A to spoil. The oldest retained samples of Lith A are now over ten years old, have not changed colour and work just like fresh solution. A mistake on my part cannot be ruled out either; rather than spending ages puzzling over it – it won’t do any good now anyway – the spoiled solution will be replaced. Regards wm
