LarryD:
Put metal, stainless steel and/or copper, scouring pads into an old tin can to make a convenient soldering iron tip cleaner.
Any preference between stainless and copper. Is there any benefit to using both metals or was that just because you bought a combo pack of pads? What about brass? I think that's what's in the one I have. Have you compared these to using a wet sponge? I've never used a sponge but always wondered if there was a drawback to this style of tip cleaner.
LarryD:
Use an old nail polish bottle to hold liquid flux for soldering.
Any reason why you prefer this to the squeeze bottles with the syringe tips? I recently got one of those and much prefer it because if I accidentally knock the bottle over it's only a drop spilled at the most.
