To clear a clogged double kitchen sink, start by bailing out excess standing water using a cup and bucket. Tightly seal one sink drain opening with a wet washcloth to maintain airtight pneumatic pressure, place a cup plunger firmly over the opposite open drain, and plunge vigorously 10 to 15 times to force the grease and food clog through the central sanitary tee and P-trap. If plunging fails, place a bucket underneath the U-bend trap, unscrew the slip-joint nuts, and manually clean out the accumulated sludge. Verification: Reassemble all plumbing fittings securely and run warm water down both basins simultaneously to verify smooth, balanced drainage.
