SRA Sal Ammoniac Tinning Block - 100 Grams

Nothing cleans a soldering iron tip like this stuff. Maybe I'm shortening my life with it, I don't know, but it keeps my soldering tips shiny and clean which I appreciate as an EE who does board work. Just roll the tip against the sal ammoniac with a little bit of solder and you'll see your reflection on it.

Worked great for re-tinning my iron! Definitely use in well ventilated area!

One of the things I kept forgetting to buy and had a stained glass project that needed completed in a few day and it arrived quicker that I had planned.

So far, soo good! I'm quite surprised at this bar's ability to deep clean and tin my irons. I really was certain that it would be junk mostly because I had never heard of it. If you follow the very simple instructions on the bars container box, you can't go wrong! If you compare it to simple tip tinner, the tip tinner is a faster process but none that I have ever used could clean as deeply as this bar does without causing some damage to the tip. I like it.

Great product, highly recommended but I'm guessing the person writing the description is a man cause they boast 5" but whipping out the ole measurey device and I get 3 1/4" x 2" x 3/4" . It says it has an expiration date, I'll know more in 2026...

That it works wonderful

This works effectively. It is an old timer's solution but it is more effective than some of the "Modern" ways of cleaning up a soldering iron tip. Highly recommended. This block will last a long, long time. Don't file or sand off the soldering tip. Look on YouTube for demonstrations of how to use it. Be a little bit patient in performing the process of heating the soldering tip in contact with the sal amoniac block. If you haven't damaged the plating on the soldering tip, you'll return the tip to like new condition.

A lab tech told me years ago this stuff was horrible to use on a solder iron, deteriorated the tip fast. I don't know about that but when you inherit a solder iron that just does not wet, this is the tool to get it cleaned up.

I purchased this so I could recycle gold jewelry. Most gold for casting these days has all kinds of additives to make it perform and flow better. These additives make the gold unsuitable to re-melt and roll into sheet and wire, the ignots become brittle and crack and in most cases your forced to send the gold back for refining and only recover a fraction of it's true worth. Use this in the melting dish with some activated charcoal and the poured ignot will have most of the additives removed, especially the tin from solders and any lead (amoung other things). It may also remove some silver and copper but the loss shouldn't affect the kt of gold. It's a basic refiner but the results speak for themselves. I'm able to roll the ignots into sheet without cracking and draw into wire without problems. I did add a gram or so of 24kt to each 1/2 ounce melt but it's not a requirement from what I've read. I find myself annealing slightly more often than I would with fresh gold. You can find detailed instructions online for this. I've reclaimed almost 2 ounces of 10k,14kt and 18kt gold that I'm using for fabrication purposes with this method. The results have been surprising to say the least. This method seems to have fallen out of use but was quite popular 50-100 plus years ago. Good luck and follow safety and ventilation guidelines

A+++++++++

Works very very well. Best way to keep your iron tips in good working order for a long time.

It's used in the soldering process.

Perfect for tinning the soldering iron, brick is a nice size and priced fair. Just DON'T breathe the smoke. But you knew that. CHEERS.
