Using this faucet seat wrench set is easy. First, identify the type of faucet seat you need to work on - whether it's hexagonal, square, stepped, or tapered. Then, choose the appropriate end of the double - ended wrench from the set. Simply insert the wrench into the faucet seat and turn it to remove or replace the seat. When using the wrenches, make sure to apply even pressure to avoid damaging the seat or the wrench. After each use, wipe the wrenches clean with a dry cloth to prevent rust. Store them in a dry place to maintain their durability. Since they're made of heat - treated steel, they're built to last, but proper care will ensure they serve you well for a long time.
