# Convertible Top Cleaning: Fabric vs Vinyl, Protectants and Cost

To clean a convertible top, rinse it, spray a cleaner made for convertible tops onto the wet surface, scrub lightly with a soft brush, rinse thoroughly, let it dry completely, then reapply the protectant that matches the material: a water repellent such as 303 Fabric Guard or RaggTopp Fabric Protectant on cloth, or a UV protectant on vinyl. A DIY kit costs about $30 to $60, and estimates for a professional clean and reseal generally run about $100 to $250 on a standard convertible in 2026.

Fabric and vinyl tops look similar from a distance but need different protectants. Using the wrong one is the most common mistake, and it can leave a vinyl top greasy or a fabric top blotchy.

## Key facts

- **Fabric (cloth) tops need water repellent**; vinyl tops need UV protectant
- **303 Fabric Guard needs 70°F or warmer** and 12 to 24 hours to cure
- **RaggTopp says to reapply its vinyl protectant every 3 to 5 weeks**
- **Avoid pressure washers and brush car washes**; soft tops are built to last 15 to 20 years with care
- **DIY kits cost about $30 to $60**; pro clean and reseal estimates generally run about $100 to $250

## Fabric or vinyl: how to tell

Fabric tops, sometimes called cloth or canvas, have a visible woven texture like heavy denim and feel soft. Most premium convertibles from BMW, Audi, Porsche, Mercedes and Mazda use multi-layer fabric tops. Vinyl tops are smooth or have an embossed grain that looks like leather, feel slick, and are common on older domestic convertibles, Jeep soft tops and many aftermarket replacements.

If in doubt, check the owner's manual or drip a little water on the top. Treated fabric beads water but you can see the weave; vinyl looks and feels like plastic.

_Fabric vs vinyl convertible tops_

|  | Fabric (cloth) | Vinyl |
| --- | --- | --- |
| Look and feel | Woven, soft | Smooth or grained, slick |
| Main threat | Loss of water repellency, staining, mildew | UV fading, cracking, cloudy windows |
| Protectant type | Fluoropolymer water repellent | UV protectant |
| Examples | 303 Fabric Guard, RaggTopp Fabric Protectant | RaggTopp Vinyl Protectant, 303 Aerospace Protectant |
| Typical reapplication | Monthly per 303 for exposed cars; every 3 to 6 months garaged, or when water stops beading | Every 3 to 5 weeks per RaggTopp |

## Step by step cleaning

Pick a cool, shaded day. Sun dries the cleaner before you can rinse it and blows protectant off in the wind. For fabric tops, 303 says to apply its Fabric Guard only in 70°F weather or warmer so it cures properly.

- Vacuum a dry fabric top with a soft brush attachment to lift loose dirt and debris
- Rinse the whole top with a garden hose, not a pressure washer
- Spray a convertible top cleaner evenly over the wet surface
- Let stubborn stains and bird droppings soak 10 to 20 minutes
- Scrub lightly with a soft brush in straight lines, front to back
- Rinse thoroughly before the cleaner dries
- Let the top dry completely, usually several hours, before applying protectant

> Stiff bristles open up the weave of a fabric top. Use a soft or horsehair brush.

## Applying protectant

On fabric, mask off the glass and paint with plastic sheeting or tape and towels, because repellents bond well to glass and leave streaks. Spray 303 Fabric Guard or RaggTopp Fabric Protectant in a light crisscross pattern until the surface is evenly damp but not soaked. RaggTopp's kit directions call for spraying from 12 to 14 inches, waiting 15 minutes between coats and allowing 24 hours to fully bond; 303 calls for 12 to 24 hours of cure time before the top gets wet. Wipe any overspray off the paint and windows right away.

On vinyl, spray the protectant onto the dry top and wipe it in with a microfiber towel. RaggTopp says its vinyl protectant restores UV protection that weakens over time and should be reapplied every 3 to 5 weeks. Do not use fabric repellent on vinyl or vinyl dressing on fabric.

Kits that bundle cleaner and protectant, such as RaggTopp's or Chemical Guys' convertible top kit at about $55 with a horsehair brush and towels, are the easiest way to buy matched products.

## How often, and what to avoid

Wash the top whenever you wash the car, and remove bird droppings and tree sap immediately; they stain fabric quickly. Do a full clean and protectant application every three to six months for a fabric top on a daily driver, more often in strong sun or if the car sits outside. 303 recommends cleaning and protecting a fabric top about once a month depending on exposure; water no longer beading is the practical sign.

Haartz, which makes many factory cloth tops, says soft tops are built to last 15 to 20 years with care and advises avoiding high-pressure washes. Skip automatic washes with heavy brushes, harsh degreasers and household detergents. Keep iron removers and strong chemicals off the top during exterior detailing; CarPro specifically warns against using IronX on fabric convertible tops.

Plastic rear windows on older tops scratch easily and cloud with age. Clean them with a plastic-safe cleaner and a soft microfiber, never with paper towels or household glass cleaner containing ammonia. Many owners add a plastic polish once or twice a year to keep them clear.

## What a professional charges

Detailers usually sell convertible top cleaning and protection as an add-on to an exterior detail or as a standalone service. Estimates generally run about $100 to $250 on a standard two-door convertible in 2026, depending on condition, whether mildew treatment is needed, and how many coats of protectant are applied. Heavily stained or mildewed tops sit at the top of that range, and a top with tears or delamination needs an upholstery shop, not a detailer.

Ask what products the shop uses and whether they mask the glass and paint before spraying. If you are also booking a full detail, see /guides/how-much-does-a-full-detail-cost for base pricing.

Mildew on a fabric top usually starts where dirt sits, along seams and the rear window. Treating it early with a top-safe cleaner is far cheaper than replacing the top.

## Frequently asked questions

**Q: How often should I treat my convertible top?**
A: Fabric tops every three to six months, or whenever water stops beading. Vinyl tops more often; RaggTopp says every 3 to 5 weeks for its vinyl protectant.

**Q: Can I take a convertible through a car wash?**
A: Touchless washes are lower risk. Avoid automatic washes with heavy brushes and never use a pressure washer close to the top.

**Q: Is 303 Fabric Guard safe for vinyl tops?**
A: No. Fabric Guard is a water repellent for fabric. Use a vinyl protectant such as RaggTopp Vinyl Protectant or 303 Aerospace Protectant on vinyl.

**Q: How much does it cost to have a convertible top cleaned?**
A: Estimates generally run about $100 to $250 for a professional clean and reseal on a standard convertible in 2026.

**Q: Can I use dish soap on a convertible top?**
A: It is better to avoid it. Household detergents can strip the factory water repellent from fabric and dry out vinyl. A cleaner made for convertible tops is safer and costs about $15 to $25.
