How do I check a tunnel car wash’s conveyor and brush maintenance history?

A tunnel wash lives and dies on its conveyor, so start there. Ask who services it, how often, and whether work is done by staff or an outside technician. Request invoices for chains, rollers, drive components and sensors. Then walk the tunnel with the owner and ask which parts are original and which have been swapped. The answers should line up with the paperwork.

Brushes and cloth wear steadily, so ask how they are tracked. A careful operator can tell you when each set was last replaced and what the supplier recommends. Watch a few cars go through. Listen for strain, look for uneven contact or streaking, and ask the staff what they fix most often. Staff usually know the weak points before the books do.

Bring in an independent equipment technician if you can, and ask them to inspect rather than rely on the seller’s summary. Check whether a breakdown ever closed the wash for days, because lost wash days affect the revenue you are looking at. Ask for any manufacturer manuals and parts lists, and confirm who holds the service relationship. Your accountant can help you judge whether deferred upkeep should change your offer. Keep copies of everything the owner shows you, with dates.

Key takeaways

• Match invoices and service logs to what is physically installed in the tunnel.
• Have an independent technician inspect the conveyor and brushes before you decide.
• Ask how often breakdowns closed the wash and what that cost in lost days.
