Treadmill belt silicone lubricant (Fiveways BN1)

Hi, does anyone have any treadmill belt silicone lubricant? These usually come in a 100ml or larger plastic bottle which have a nozzle to apply it under the belt. Only a small amount is needed as the belt is starting to make a rubbing sound and requires squirting a bit underneath on the edges. Can collect whenever is convenient for. you. Thank you. Kind regards, Jazz
