so i have a cloning tray. i used it for about 2 months. it has a lot of salt build up. i tried hot water and about 6 denture cleaning tablets. it got off some of it. the tray with plugs is only $16. it's a nice tray and an easy switch, so i bought a second one. i want to use one while i clean the other. so my second one is getting dirty now and i need to switch them.
so...................How do i remove built up salt deposits from my clone tray?
