I am writing a comment in line with the cleaning chain also from PT. It is my first cleaning chain, it is quite heavy, but for the fact that it is more or less made of 1 piece, it looks very high quality. The cleaning is also very good, but you don't need to turn the chain too fast, because then it tends to blow through the small hole at the top where the preparation should probably be poured. I cleaned it with the original preparation and it was really cleaned very well. It's actually worse than cleaning the buckle itself. You can pick out the whisky-type things from it, but it's probably best to just pour it out and rub it on a little. The first time I tried to rinse it in water, but I waited and it was confirmed that it was not an ideal solution since I use oil for the chain. And oil and water do not mix. So next time I'll just pour it out and wipe it off.

The consistency and smell are like linseed oil , but it really dissolves grease nicely, plus it's environmentally friendly and not heavy chemicals.

It's hard to open but otherwise clean.

But I'm not very satisfied, it smells quite bad and I also used it in an ultrasonic cleaner but it didn't clean it very well. I have better experiences with Weldtite, for example.
