What is the best caravan cleaner for your setup? That depends on what you're dealing with - winter algae creeping across the roof, black streaks down every panel, road film from the motorway, or dried-on bug splatter across the front. 

Every caravan cleaner on the market tackles these jobs differently, and picking the wrong one usually means wasted product and a finish you're still not happy with. That’s why we created this guide ranking the best caravan cleaning products available right now so you can skip the guesswork. 

Key takeaway: Jennychem’s Caravan Cleaner is the strongest option for the money, and customers consistently come back for more after seeing how effective it is in restoring a pristine shine. Learn more below.

Comparing the Best Caravan Cleaning Products

Here's a side-by-side of the best caravan cleaning products in this roundup before we get into the details.

Note: The price column only tells half the story. Concentrates stretch far further per bottle than ready-to-use products, so cost per wash is where the real comparison happens. A 5L concentrate at 1:25 dilution gives you 130 litres of cleaning solution compared to a 500ml spray that's spent after just 1-2 sessions. 

What is the Best Caravan Cleaner?

So, what is the best caravan cleaner? This isn’t as straightforward as picking the most popular brand. It depends on the job, the surfaces you're cleaning, and how often you do it. We've listed cost, pros, and cons for each of the best caravan cleaning products below so you can quickly find the right fit.

Jennychem Caravan Cleaner

• Price: £23.00 for 5L
• Pros: Bactericidal formula kills mould and prevents regrowth. Non-caustic, safe on all exterior surfaces including GRP and window seals. Trade sizes available up to 210L, great coverage at 1:25 dilution
• Cons: Smallest size is 5L. Higher upfront spend than a spray bottle, but way cheaper per wash

This is what we hand them when someone asks us what the best caravan cleaner is. The non-caustic formula is safe across paintwork, plastics, GRP, windows, chrome, and window seals without the surface damage that harsher chemicals can cause over repeated use.

Bactericidal action is the standout feature. It kills mould and algae and slows regrowth. That's the difference between a quick rinse next time and a full afternoon scrubbing green patches off the roof and sidewalls if your caravan sits in storage between trips. 

Dilute 1:25 for a routine wash or strengthen to 1:10 when things have got properly grim. A single 5L bottle at the standard ratio gives you around 130 litres of cleaning solution. That’s months of regular washes from one purchase.

The Caravan Cleaning Kit (£59.00) bundles 5L of the Caravan Cleaner with 5L of Super Cold Wax, a Hand Cannon pressure sprayer, and a wash mitt if you want the full setup in one go. You save around £24 off individual prices this way.

Jennychem is your one-stop shop for snow foam for caravans, too. The Motorfoam Caravan Cleaner is a great option if you prefer a foam lance pre-wash stage. From traffic film remover to car wash mitts, this is your one-stop shop for keeping your caravan sparkling clean.

Autoglym Caravan & Motorhome Cleaner

• Price: £22.49 for 2.5L
• Pros: Works on both exterior and interior surfaces. Compatible with fabrics, carpets, and kitchen surfaces alongside bodywork. Well-established brand
• Cons: Used neat (no dilution) so 2.5L is all you get. Cost per wash is much higher than concentrates. No mould prevention.

Autoglym is a name most caravan owners will recognise, and for good reason. This Caravan & Motorhome Cleaner does offer genuine versatility. It works on paintwork, plastics, acrylics, fibreglass, and metals on the outside, then transitions to carpets, fabrics, and work surfaces inside. 

This covers the broadest range of surfaces on the list if you want a single bottle for the entire vehicle, from roof to cushions. But what is the best caravan cleaner? Is it the most flexible, or the most effective? Only you can answer that. 

Value is a trade-off here as well. You use it neat, so that 2.5L bottle is exactly 2.5 litres of product going straight onto surfaces. A few thorough exterior washes and you're buying another one. That adds up at roughly £9 per litre.

Autoglym recommends their Easy Sprayer for applying the 2.5L format, which is sold separately. The 1L bottle comes with a trigger sprayer that works for interior work, but can be slow across a full exterior. Be aware this formula also lacks bactericidal properties, so mould and algae return may be an ongoing battle.

Fenwicks Caravan Cleaner Concentrate

• Price: £15.00 for 1L
• Pros: Highly concentrated (up to 40 washes per bottle). Biodegradable formula, free from caustics, acids, and solvents. Over 25 years of development.
• Cons: Only sold in 1L - no bulk option for trade users or frequent cleaners. No bactericidal action against mould, either.

Fenwicks has built a loyal following among caravan owners. Two capfuls in five litres of water is the standard dilution, and the company claims a single bottle covers up to 40 cleans. The formula is biodegradable and avoids caustics, acids, abrasives, and solvents, so you can rest assured it’s safe across plastics, aluminium, acrylic windows, and GRP.

The main limitation is sizing. Fenwicks only offers the 1L bottle, so expect to reorder frequently if you clean regularly or manage multiple vehicles. There’s no way to buy in bulk other than purchasing multiple 1L bottles.

The formula handles existing algae and grime well, but doesn't include any bactericidal agents - meaning it cleans what's there without doing anything to slow regrowth between washes. Washing frequency becomes extra important if you rely on this as the best caravan cleaner.

Silky Cream Cleaner

• Price: £7.49 for 480ml
• Pros: Non-abrasive formula, antistatic finish that reduces re-soiling. Effective on black streaks and scuff marks. 40+ years on the market
• Cons: Applied by hand with a damp cloth (labour-intensive for full panels). 480ml tub is small. Not a wash product; it's a targeted treatment

Silky Cream Cleaner sits in a different category altogether. It's a hand-applied cream for targeted jobs like black streaks, scuff marks, and stubborn grime patches. Apply with a damp cloth, work it into the area, and rinse off. The antistatic finish helps treated surfaces stay cleaner for longer between washes, which is a nice bonus.

We’ll admit it’s a really useful addition to a cleaning kit, but it won't replace a dedicated wash concentrate. Cleaning an entire caravan exterior with a 480ml tub and a cloth would take most of a day, and you'd likely need more than one tub to finish the job. Think of this as your spot cleaning solution along with one of the other best caravan cleaning products on our list.

That Leisure Shop Citrus Bug Remover

• Price: £5.99 for 500ml
• Pros: Citrus-based formula, spray trigger for quick application. Compact bottle.
• Cons: A bug remover, not a full caravan cleaner. 500ml goes quickly on larger surfaces. Minimal product detail available from the manufacturer

This does exactly what the name suggests - removes bug splatter. You probably know all too well how the front panel and windscreen end up plastered after a long motorway run. A citrus spray like this one eradicates dried-on residue faster than a general wash product will. Spray it on, let it dwell, wipe it off.

Like the Silky Cream Cleaner, it’s a handy thing to keep in the caravan for spot work between full washes. It handles front panels, mirrors, and the windscreen well enough. Just don't expect it to replace a proper exterior clean - the 500ml bottle isn't going to stretch to a full caravan.

Final Words on the Best Caravan Cleaning Products

Each of these formulas was handpicked as one of the best caravan cleaning products for a reason. They all fill a slightly different role, and some work better as part of a wider kit than as standalone solutions. 

So what is the best caravan cleaner overall? Jennychem’s is the most effective, value-packed option for a proper all-round exterior wash. Non-caustic safety on any surface, bactericidal action that actually prevents mould returning, and a 5L concentrate at 1:25 dilution that outlasts everything else on this list pound for pound.

Frequently Asked Questions

How do I get my caravan to shine again?

Start with a proper wash. Rinse off loose dirt and grit first - a pressure washer or hose is fine for this step. Apply a diluted caravan cleaner over one panel at a time, agitate with a soft mitt working top to bottom, and rinse before the product dries on the surface. Apply a cold wax or rinse wax once the exterior is clean, but while panels are still wet. Our Super Cold Wax at 1:25 dilution works well. Spray it on, rinse the excess, and towel dry to prevent water spots.

What is the best thing to clean a caravan with?

A purpose-built caravan cleaning concentrate will outperform washing-up liquid or household sprays every time. Look for something non-caustic, concentrated for value, and ideally bactericidal if your caravan spends any time in storage. 

What is the best thing to clean caravan windows with?

Skip anything abrasive. Caravan windows are often acrylic rather than glass, and they scratch easily. A dedicated car glass cleaner paired with a soft glass cleaning cloth gives you a streak-free result without risking surface damage.

What is the best polish for a caravan?

A good wash followed by a rinse wax is usually enough for routine maintenance. However, a car polishing compound will cut back the damaged layer and restore the surface if paintwork or GRP has dulled, oxidised, or picked up light scratches. Work in small sections with a soft applicator pad, buff off with a clean microfibre, then seal with your wax of choice.
