The Common RV Cleaning Mistake That Leads to Costly Interior Damage

Cleaning an RV seems pretty straightforward, yet the materials inside a camper react very differently from what you’re used to at home.

People often spray, wet mop, and wipe using the same routine they use in, for example, a home kitchen or living room. But what does that mean once moisture starts collecting in the seams and corners of lightweight RV cabinetry?

Things can break down far sooner than expected.

How Household Cleaning Habits Create RV Damage

RV interiors are built to keep weight down, which often means they’re built with cheap pressboard, thin veneers, and composite finishes. These materials don’t handle moisture or heavy cleaners very well.

Let’s break it down.

Moisture collecting where it shouldn’t

• Wet mopping pushes water into cabinet bases
• Spray cleaners puddle in seams and around corners
• Moisture can loosen the surface layer on cabinets, tables, and trim, causing it to bubble or peel over time

Using cleaners meant for tougher surfaces

Many household cleaners are built for tougher materials than what you find inside most campers. RV cabinets, tables, and trim use lightweight finishes that don’t handle strong cleaners well. A product that works great on a kitchen stove or solid wood cabinet can dull or wear down an RV surface faster than people expect.

Smarter Ways to Clean an RV Interior

These methods keep moisture under control and help protect interior finishes.

• Use a damp cloth instead of a soaking wet one. Wring out cloths so they are barely moist. This gives you enough cleaning power without letting water settle into seams.
• Spray the cloth instead of the surface. This prevents liquid from running into corners or spreading across pressboard surfaces.
• Hand clean around cabinet bases. Skip the mop in these areas. A hand wipe prevents water from seeping into the bottoms of cabinets.
• Pick gentle, non-abrasive cleaners. Products labeled for RV or marine interiors are usually safer since the materials overlap. If a product is very strong or designed to cut heavy grease, it may be too aggressive.
• Test on a hidden spot. Different RV manufacturers use different finishes. A quick test tells you if a cleaner leaves marks or dulls the surface.

Protecting Your RV Interior

Small adjustments in your routine help avoid repairs down the road. Using less water, choosing gentler products, and keeping moisture out of cabinet seams help your interior stay in better shape. These simple habits reduce swelling, peeling, and other long-term issues that come from using household cleaning methods on RV materials.
