Open the Bottle: Carefully unscrew and remove the bottle’s current cap and brush.
Clean the Old Brush (if needed): Use a paper towel to wipe off any remaining glue or residue from the old brush and cap.
Separate the Brush from the Cap: Hold the cap firmly in one hand, then grasp the brush with a paper towel using your other hand. Gently pull the brush away from the cap until they come apart.
Insert the Replacement Brush: Take the new glue brush and place it inside the bottle.
Attach the New Cap: Put the new cap on the bottle and screw it on tightly. As you do this, the replacement brush will attach itself to the cap securely.
Check the Brush Fit: Once the cap is tightly in place, open the bottle again to ensure the new brush is properly attached and ready for use.
