My ooch smoov yoyo keeps breaking polyester string, does anyone know how to fix

please give me some ideas

What do you mean break the string? Like it cuts the string?

I think it’s the strong bead blasting that they put into the bearing seat. Get a sock, and wipe down the bearing seat for like an hour and thirty minutes, and it should be OK.

Alternatively get some heavy duty scotch brite and rub it for a minute or two
