A sensitive area in the bathtub is the drain. The metallic material with which it is made should be stainless steel but this is not always the case. Time and improper cleaning products cause rust in the bathtub drain and this part must be repaired or replaced.
Steps to repair bathtub drain rust:
-Remove the drain valve.
-Sand all the existing rust on the pieces.
-Clean and dry well.
-Apply a lacquer product.
-If it is badly damaged, it is better to replace it with a new stainless steel drain valve.
