Yes, pouring boiling water down a metal shower drain can help dissolve and flush away minor clogs composed of accumulated soap scum, hair oils, and greasy residue. The thermal heat softens congealed soap and grease, allowing water pressure to push the debris down the line. However, boiling water is ineffective against solid hairballs and must never be used on PVC plastic pipes due to melting risks. Verification: Run hot tap water afterward to confirm whether drainage speed has improved.
