It is normal for club parts to get dirty through normal use. If you'd like to get them fresh and clean again, we have information about how to do that below.
Club body and handle:
If your club body and handle are dirty, you can wipe them down with soapy water or rubbing alcohol. Do not submerge your vision clubs in water.
For grip club bodies, you may want to use a small brush (a toothbrush works great) to clean between the ridges.
You can clean the club while it's assembled, or you can disassemble the club to do a more in-depth cleaning: https://flowtoys2.freshdesk.com/support/solutions/articles/6000214589-vision-clubs-swapping-out-club-bodies-handles-knobs-caps
Club caps: Whether you have 3D printed club caps or the newer silicone caps, you can wash off any dirt with soap and water, and a solvent like rubbing alcohol will help with grease/oils.
If your 3D printed club caps are yellowing, it is likely because the TPU material is discoloring with UV radiation and oxygen. This is accelerated by heat, so we don't recommend putting them in the dishwasher.
In 2024 we transitioned from the 3D printed caps to silicone ones, which are much more resilient and do not discolor over time. If you'd like to get some silicone club caps to use instead of the 3D printed ones, we offer them on our site here: https://flowtoys.com/parts-1/club-parts
If you would like your clubs to look fresh, you might want to get 2 sets of parts (bodies, handles, caps, knobs) - one for indoor use when you want your clubs to look nice, and a set for outdoor use ;)
