Yes. That tan coloured stuff. Are you using a no clean flux ?
Safewash works great for ye olde rosin core stuff but no clean is
intended not to be cleaned and is really stubborn.
If I use IPA or fluxclene, it cleans the (no clean) flux off but leaves a thin
sticky residue over everything unless I use large amounts of IPA.
My current method is a quick fluxclene scrub and then the safewash /
water / saferinse sequence.
