Thousands of Jehovah's Witnesses Scrub Downtown Milwaukee Before Baird Center Convention

Downtown Milwaukee streets got scrubbed, pressure-washed and swept this week by an unusual crew: thousands of Jehovah's Witnesses volunteers preparing the city for a massive international convention. The cleanup began Wednesday, ahead of a gathering expected to draw 21,000 participants, including 5,000 delegates from 19 countries, to the Baird Center.

Volunteers pressure washed walls and streets beneath the Baird Center earlier in the week and targeted 17 parking lots near the venue, according to the Milwaukee Journal Sentinel. Some of the equipment used for the job, including pressure washers, was borrowed from local Jehovah's Witnesses and area businesses. Downtown roads around the venue, including stretches tied to the event footprint, will remain closed until September 1, according to CBS 58, with closures affecting West Kilbourn Avenue, North King Drive and eastbound West Wells Street.

Among the volunteers was 46-year-old Joe Laufenberg, who practices the Jehovah's Witnesses faith and was one of 10 volunteers sweeping and picking up trash outside the Baird Center. He's done this kind of work before, having cleaned windows ahead of a convention in Green Bay. Laufenberg said his family saw visitors coming to Milwaukee and viewed the cleaning as a chance to give them the best possible view of the city.

A Global Ritual, Not a One-Off Favor

The scrubbing isn't a spontaneous act of civic goodwill so much as standard operating procedure. Convention spokesperson Tyrel Whiting said cleanliness is important for all Jehovah's Witnesses events, and that the organization provides similar cleaning services in every city it visits, according to the Journal Sentinel's reporting. Jehovah's Witnesses host hundreds of regional conventions every year, and the practice of floor-to-ceiling scrubbing before large assemblies has been documented as a longstanding global tradition, per AP News.

Whiting noted that the area beneath the Baird Center was already very clean before volunteers arrived, framing the effort less as remediation and more as a token of gratitude toward the host city. The cleanup, organizers say, also helps prepare the Baird Center as a place of worship and welcomes visitors ahead of the main sessions. Jehovah's Witnesses have said they aim to leave cities cleaner than they found them.

Inside the venue, volunteer duties extended well beyond the streets outside. Crews scraped chewing gum off floors, scrubbed main convention halls and set up thousands of chairs before sessions began, according to CBS 58's on-the-ground reporting.

Milwaukee's Reaction: Cautious Novelty

Tiffany Shepherd, a spokeswoman for Milwaukee's Department of Public Works, said she isn't aware of other organizations that have offered to clean city streets in the past, underscoring how unusual the gesture looks from city hall's vantage point. Milwaukee and the Baird Center have coordinated event plans for over a year to accommodate the convention's scale.

This year's gathering marks Milwaukee's turn as the first of two U.S. host cities for the 2026 global convention series, themed “Eternal Happiness” and staged in 19 cities worldwide alongside international locations. San Diego will host the series' other U.S. stop in November. Selection of host cities happens years in advance, based on venue capacity and regional transportation links.

Why Milwaukee Can Handle the Crowd

The city's ability to absorb 21,000 visitors traces back to the Baird Center's $456 million expansion, completed in May 2024, which doubled the venue's footprint to 1.3 million square feet and added 300,000 contiguous square feet of exhibit space along with 52 meeting rooms. The facility also earned LEED Gold certification in February 2025 after adding features such as a 320,000-gallon stormwater retention system, rooftop solar panels and an organic digester capable of diverting 438 tons of food waste annually.

The convention is the latest in a string of large bookings testing that expanded capacity. Northwestern Mutual's annual meeting brought 11,000 attendees downtown in July, and Milwaukee has also hosted the 2024 Republican National Convention, which drew an estimated 50,000 visitors to the city. Wisconsin Center District projections tied to the expansion estimate the Baird Center could draw 100,000 additional out-of-state visitors annually, generating $12.6 billion in total spending and $150 million in new state tax revenue over 30 years, according to CAA ICON.

That growth fits into a broader tourism surge in Milwaukee County, which reached a record $4.321 billion in total economic impact in 2024, driven by $2.439 billion in direct visitor spending supporting more than 28,000 local jobs, as Hoodline has previously reported. For Laufenberg and the volunteers scrubbing tunnels and parking lots this week, though, the motivation described to the Journal Sentinel was simpler: leaving a good impression on a city they're just visiting.
