RV Detailing Checklist: The Complete Step-by-Step Process

RVs and motorhomes take longer to detail than cars for a simple reason: there's more surface area, more specialized components (roofs, awnings, slide-out seals), and a lot more that can go wrong if you skip a step out of order. This checklist walks through a full RV detail top to bottom, in the sequence that avoids re-doing work — starting with the roof, since anything that runs off it will re-dirty everything below.

1. Roof inspection and cleaning (do this first, always)

  • Identify the roof material first — EPDM rubber, TPO, or fiberglass — since cleaners and UV protectants differ by material and using the wrong one can degrade rubber roofing
  • Sweep off debris and check all seams, vents, and skylights for cracked or lifting sealant before you get them wet
  • Wash with a roof-safe cleaner (avoid petroleum-based cleaners on rubber roofs) and a soft brush on an extension pole
  • Rinse thoroughly — any leftover cleaner residue will streak down the sides once you start washing the exterior
  • Apply a UV protectant on rubber/TPO roofs if the customer is on a protection plan; note any sealant issues found for the customer's records rather than attempting roof repairs yourself unless that's an explicit part of your service

2. Awnings, vents, and exterior fixtures

  • Extend the awning (with permission) and brush off debris before wetting it down
  • Clean both sides of the awning fabric with a non-abrasive cleaner; check for mildew spotting, which needs a dedicated mildew remover rather than regular soap
  • Wipe down roof-mounted A/C shrouds, antennas, and vent covers — these accumulate black streaking that regular washing misses
  • Retract the awning fully and confirm it's dry before closing, to avoid trapping moisture that causes mildew

3. Exterior wash and black streak removal

Black streaks running down from roof seams and window edges are the single most distinctive RV exterior issue and require a dedicated streak remover — regular car wash soap will not touch them once they've set. Work from the top down in sections so you're always rinsing dirty runoff off surfaces you haven't cleaned yet.

  • Pre-rinse the full exterior to loosen surface dirt and road grime
  • Apply black streak remover to affected areas and agitate with a soft brush; let it dwell per the product's instructions before rinsing
  • Wash the full body with a pH-neutral soap, working top to bottom, side to side
  • Clean and dress exterior storage bay doors, steps, and the entry door separately — these get the most hand contact and show grime fastest
  • Detail wheels, tires, and any exposed chassis/undercarriage components accessible from ground level

4. Fiberglass/gelcoat protection

Once clean and dry, inspect the fiberglass or gelcoat for oxidation — chalky, dull patches are common on RVs that sit outside between trips. Light oxidation can be addressed with a one-step cleaner wax; heavier oxidation needs compounding similar to marine gelcoat correction before wax or ceramic coating will bond. Finish with a coat of wax, sealant, or ceramic coating depending on the package the customer bought — this is also the point to note and photograph any existing chips, delamination, or clear-coat failure so it's documented before you touch it, protecting you from disputes later.

5. Interior detail and slide-out seals

  • Vacuum and clean interior slide-out tracks and seals — these trap debris that can tear rubber seals over time if ignored
  • Wipe down all interior surfaces: dash, cabinets, countertops using cabinet-safe (non-ammonia) cleaners on wood finishes
  • Clean windows and mirrors inside and out, including the windshield and any skylight/vent covers
  • Vacuum and, if included in the package, shampoo carpets and upholstery
  • Sanitize the bathroom and check for any reported plumbing or slide mechanism issues to flag for the owner — not to repair, but so nothing gets blamed on the detail afterward

Frequently asked questions

What order should you detail an RV in?

Start with the roof, then awnings, vents and exterior fixtures, then the exterior wash and black streak removal, then fiberglass or gelcoat protection, and finish with the interior and slide-out seals. Working top to bottom keeps runoff from re-dirtying surfaces you already cleaned.

What cleaner is safe for an RV rubber roof?

Identify the roof material first, since EPDM rubber, TPO and fiberglass need different products. Use a roof-safe cleaner with a soft brush and avoid petroleum-based cleaners on rubber roofs, because they can degrade the membrane.

How do you clean an RV awning without causing mildew?

Brush off debris, clean both sides of the fabric with a non-abrasive cleaner and use a dedicated mildew remover on any spotting. Make sure the awning is completely dry before you retract it so moisture is not trapped inside.
