Hola! Thank you for checking out the Delta RP51503 bonnet nut. We recommend soaking a towel or washcloth in a solution of 50% white vinegar and 50% water solution. Then, wrap it around the bonnet to loosen any hard water or corrosion that may be keeping the bonnet tightened. Once loose, use a strap wrench or adjustable wrench to unscrew the bonnet nut counterclockwise to remove it. We hope this information helps.
