I was more interested about the chemicals used in the ultrasonic bath.
And if you were only doing ultrasonic. Apparently not ![Grin ;D](https://chinertown.com/Smileys/default/grin.gif)
haha nah ultrasonic ain't good enough for factory grease. fac grease can be really thick shit.
right sorry, if you're not from australia, those chemicals probably make 0 sense.
metho = methylated spirits, denatured alcohol
turps = mineral turpentine, can be sold as a close variant white spirits in other countries
petrol .. well just regular pump petrol. Just anecdotal, but I found 1 petrol bath seems to reduce the number of turps baths needed by 2 for whatever reason
i still give a very small turps bath after i boil the chain before rewaxing. it appears perfectly brand spank clean after boiling prior to rewaxing, but once you run it through a small turps bath, it definitely seems to get more black shit out. i don't know for sure, but i'm just assuming it's from a build up of greasy road grime crap contaminating the chain and then not coming out when i boil it. just my experience, may or may not be true for anyone else.
