Do not pour grease or fat down your drain in an attempt to loosen it.
Send a handful of baking soda and hot water down the drain. Pour 1 cup (8 oz) of vinegar and hot water down the drain. Use a drain snake to clean out any blockages.
Be careful not to drop any screws down the drain. Set them aside somewhere safe and outside of the shower in case you will be putting the shower drain back in later.
Handle the pliers carefully so that you don’t accidentally dent your shower drain.
If the drain won’t budge, apply more lubricant.
If you know that you plan on discarding the shower drain, you may handle it more roughly.
