If you have some swivels that are not working correctly, we can definitely help out :)
If you find your bearings are no longer spinning smoothly, they may just need a few drops of oil, though they probably have some dirt or thickened lubricant inside and need to be cleaned first and re-lubricated.
Here are 2 methods:
The proper way: The first step is to rinse dirt and old oils out of your bearings with kerosene or mineral spirits, then rinse them off with 99% isopropyl alcohol. Use a small cap to hold just enough to soak the swivels and shake/spin them out a few times until they feel smooth/grit free. Lubricate your clean and dry bearings with a drop or two of thin machine oil or bearing lube like you would find for skates, sewing machines, or hair clippers. Spin and wipe clean with tissue.
The quick and easy way: (might not get them quite as clean, but should do the trick) Use "Tri-Flow" bicycle lubricant, the dropper or spray version are fine. Tri-Flow is designed not to leave any residue behind. Drop enough in the bearings to rinse out the old stuff/dirt, spin and repeat until they feel smooth. Wipe dry with rags/tissue.
→ DO NOT use WD-40, or anything like it! WD-40 and other cheaper lubricants leave behind a film that actually collects dirt and dust, and make your bearings sticky and gritty, and the grit will ruin your swivels. They also contain many toxic substances specifically for displacing water (Water Displacement-40), which is not necessary for poi swivels.FYI: some lubricants can damage plastics. Please be careful not to get any on your plastic flowtoys parts!
We hope this helps, and if you have any questions please contact us!
