How Safe Is It to Wash Gas Pumps? Here’s What Every Contractor Should Know
If you’re cleaning a gas station — whether it’s part of a maintenance contract or a one-time project — one of the most delicate parts of the job is washing around the pumps.
So, can you spray them down?
Yes… and no.
Modern Pumps Are Built Tough — But Not Indestructible
Today’s gas dispensers are weather-resistant. They’re built to handle rain, snow, and the occasional splash. Manufacturers use:
- Sealed electronics compartments
- Water-shedding touchscreens and keypads
- Drainage channels to prevent pooling
But weatherproof isn’t the same as pressure-washer-proof. High-pressure water can force its way past seals, damaging card readers, screens, and internal wiring.
The Risk Is Real
Even a gentle spray can cause trouble if:
- It hits seams or vents directly
- Warm water softens seals
- The spray comes from below, bypassing drip shields
Water + electronics + gasoline vapors = not a good mix.
Pro Tips to Keep It Safe
- Cover the electronics with waterproof covers or heavy-duty plastic.
- Lower your pressure — under 300 PSI near pumps, with a wide-angle tip.
- Avoid direct spray on seams and card readers.
- Use chemicals smartly — low-pressure application, rinse from the top down.
- Inspect after cleaning before putting the pumps back in service.
Bottom line:
Modern pumps can handle weather, but they’re not designed to take a direct hit from your wand. Protect them first, clean carefully, and you’ll avoid costly repairs.
