Select Home Depot Stores: 14-oz. Sea Foam Engine Cleaner & Lube Spray $1.30 (Pricing/Availability May Vary)

Home Depot has Seafoam Upper Engine cleaner on clearance for 90% off. My store has 90 in stock at $1.30 per can. Note: this is not normal seafoam. This is a spray can for spraying into engine to clean passages or DI intake valves. YMMV
