4th Ave Cleaners in downtown San Diego's Gaslamp Quarter operates a combined laundromat, dry-cleaning counter, and alteration shop from Fourth Avenue between F and G Streets near the Horton Plaza district. The GreenEarth solvent system replaces conventional perchloroethylene with a silicone-based process that returns garments without chemical odor, a method shared by tailoring operations like B Street Tailoring & Cleaners for handling delicate suit fabrics. Self-service coin machines run alongside attended wash-and-fold at $2.00 per pound, and an in-house seamstress handles hemming, tapering, and zipper replacement on the same visit as garment cleaning. A dedicated Airbnb linen program processes sheets, towels, and bedding for short-term rental hosts whose turnover cleaning comes from services like San Diego Short Term Rental Cleaning LLC. The highest-volume contracts bundle same-day dry cleaning, bulk wash-and-fold, and full alteration turnaround for hotel guests and convention attendees steps from Petco Park.
