I been doing that for ages… only problem is the Chain Cleaners are not cheap… I was even using it to clean my hands after fiddling on the bike:) it is a very strong solvent… that’s all:)
Just a word of caution. If it’s a strong solvant you should make sure its safe to use on O Ring chains. I’d hate to think a freebie cost you the price of a new chain:doze:
