I have been using the Lansinoh on my O rings and threads and It is working really well. It is very pure. It is made for Breastfeeding mothers. I used it for my irritation of a cpap mask. Noalox was working well on my threads till it was time to clean them. It was such a chore keeping the threads clean. Now I can just wipe them off with a microfiber wash cloth and put on another tiny dollop of the Lansinoh. This is water soluble. Maybe some of you guys would like to try it. I got it at Walgreens. I think any drugstore would have it. It is so important to keep our threads clean for our GG to work at it's best. I just love doing it the easy way.
