Heico Permawash for clearing Pt/Pd

[Donsta]

Following some prints which I could not clear in EDTA (basically anything I develop with potassium oxalate will not clear in EDTA nor an EDTA sodium sulphite mixture), I tried some Heico permawash. It seems to work really well and is dirt cheap - are there any issues I need to consider before making it my standard clearing agent?

I've used PermaWash for Pt./Pall for many years now. If it works-use it!
