Moersch easylith shelf life in opened bottle

Laci Toth · Jun 1, 2021

Hi dear all,

I’ve done lith printing for a while with this developer but back then I’ve ordered the smallest amount 200ml and I used them up quite fast so I couldn’t get to know how long do they last in their bottle after opening. It was back in the UK and the store had always in stock so was no shipping cost at all. I moved to Hungary since then and as the shipping cost is €20 no matter which size I choose I’m about to order a litre.
Maybe it’s just me but I only found infos how long do they last in an airtight bottle. It says an unopened lasts almost indefinitely.

I've had Moersch EasyLith bottles opened and used them for over 5 years without any problems! Part B has almost indefinite shelf life, unopened as well as opened. And even part A worked flawlessly after all those years. Your milage may vary of course, but I would not sweat too much over it.

That’s great news! Thank you!
Do you squeeze out the air from the bottle before you put the cap back on?

My bottle is more than two years opened and works flawless - with air in it (no squeeze out).

Like the others, I have worked with bottles that have been opened for 2-4 years with no problems. I don't squeeze the air out or do anything special. I haven't noticed any difference in any of my lith prints as a result.
