How to Clean and Get Rid of RV Water Stains

If you want to protect the fabric ceilings and curtains from water stains and/or learn the best methods for cleaning them away, you are not alone.

Every RV owner I know, including me, absolutely hates them!

Leaks and condensation are the culprits that cause them, so dealing with those issues before they cause the damage is undoubtedly the main way to take care of this problem.

RV Water Stain Removal Advice

If you go on to some of the RV forums, you will always find owners asking what they can do to get rid of their water stains.

It seems that everybody has his own product or technique that seems to have worked, but some of those I have seen would cause more damage than they would fix.

For example, several people suggest spraying bleach onto the affected area.

While there is little doubt that doing this would eliminate a stain, there is also little doubt that using pure bleach, or even a mixture of bleach and water, would eventually eat right through the fabric and leave a gaping hole in the area that was treated!

Worse yet, the over spray would damage everything it touched, including carpets and upholstery.

Thus, it is important to consider the long term ramifications of using any product or method before actually giving it a try.

Also, no matter which technique you choose to use, you should remember that fabric ceilings are glued to the underlying wood.

If you put too much liquid on them or apply too much heat, the material will loosen, and the ceiling will need to be professionally stretched back into position or replaced.

This is a very expensive fix!

When to Let The RV Professionals Do It

In cases where there are many stains, people generally choose to avoid the problems that go along with making a repair themselves and seek professional help.

While this is always a good idea in theory, when it comes to cost, doing this can be outrageously expensive. One person on this forum recently got a quote from a dealership of $8,000 to repair her unit’s visible ceiling stains plus the hidden damage!

This story highlights the financial problems people might face when asking RV service departments to do work for them. They will tell you that there is no way for them to know if leaks did major damage without removing part of the ceiling fabric, but while this is true, the fact is that removal of the ceiling fabric may not be necessary.

Much depends on the extent of the visible damage and how long it has been there. My husband and I have had many coaches over the years that had water leak damage, but only one had major damage as a result. Even then, the only fabric that had to be replaced was within an upper cabinet.

The truth is that if you find and seal a leak as soon as you see a water stain and properly clean the damaged ceiling area yourself, you should incur no further cost.

However, if a leak has existed for a fairly long period of time, it is likely that a major repair will be required.

This is not the type of repair job you should attempt on your own unless you are very handy.

Do Not Try to Dry Clean RV Curtains

Some people think that dry cleaning is the way to get rid of water stains on lined, pinch-pleated RV windshield curtains. The problem is that dry cleaners will not guarantee that their solvents will work, so you could be paying good money for nothing.

Getting rid of the stains yourself, depending on how bad they are, is fairly easy, as you will see in the directions I provide below.

However, if my method does not work, you can easily an inexpensively replace them. How to Save Money on RV Window Treatment Replacements will show you what you need to do.

Forget Carpet Cleaning Services for Stained Ceilings

Because fabric ceilings are similar in structure to carpets, some people think they can be professionally cleaned and repaired by carpet cleaning services.

This is not a good idea because the chemicals they use might not be suitable, and if they wet the ceiling too much, they could damage or even destroy it.

Furthermore, if there is already underlying water damage, they could make it worse!

The Best Way to Clean RV Water Stains

As I stated earlier, many people have their own remedies for cleaning water stains from RV fabric ceilings and windshield drapes. I am sharing my own methods because after 50 years of owning and traveling in motor homes and campers, I know that they work and will not damage your coach.

The product I have always used is Woolite Oxy Deep Stain Remover. I have tried others, but this one has proven to be the safest and most effective method of removing water stains from ceilings, drapes, carpets and even upholstery that I have found.

I always carry a bottle of it when we travel so that if stains appear, I can deal with them quickly. Here is what I do:

At the first sign of water damage, have one person use a hose on the outside of the RV, from the roof down, to help the person on the inside find the source of the leak.

Repair and seal the leak immediately, then use a dehumidifier to suck the water from the affected internal areas.

  1. Once the leak has been sealed and the ceiling and/or drapes are dry, spray some Woolite Oxydeep for carpet and upholstery on the ceiling and curtain stains.
  2. Let it sit there overnight.
  3. In the morning, vacuum off the residue.
  4. If the stains are not gone, repeat the process.

In most cases this will eliminate the them. At the very least, it will make them much less visible.

(By the way, you can use this same technique on upholstered RV furniture.)

This method should leave you with a dry RV that shows minimal or zero signs of water damage and produces no mold or mildew odors.


  • If the unit is dry but this method has not removed the stains, you may need to replace the ceiling and curtains.
  • If the unit is dry but still smells, the leak has gone on too long, and it is time to repair the mold or wood rot that has resulted. If you choose not to do this, eventually your entire structure will be ruined, so do not delay.

A word of warning here: if the damage has existed for quite awhile and has caused black mold, do not, I repeat, do not attempt to repair the problem yourself. This is a serious issue that only a professional should handle, because inhaling the spores from black mold can be extremely dangerous to your health.

  1. If you find black mold in your coach, close it up, and do not enter it again until the problem is fixed.
  2. If you must drive your RV to a repair shop, wear a mask, open all windows and close off the damaged area as much as possible.

How to Prevent RV Roof Leaks

Practice Preventive Maintenance

Frustrating as this type of problem may be, there actually are simple, easy to do ways to deal with it, the main one being to take steps to prevent water from infiltrating your RV.

First and foremost, you should always make sure you properly and completely seal the exterior. This means caulking and/or taping the area around every

  • seam,
  • awning attachment,
  • hole,
  • screw,
  • bolt,
  • window,
  • door,
  • air conditioner,
  • roof vent,
  • refrigerator vent,
  • stove vent and
  • light

and checking each one of them regularly for cracks, rust and areas where water might seep in and cause damage. The attached video explains more about how perform such a check.

Anything that attaches to the exterior of your RV is a potential source for leaks, but if you seal well, you should never see a leak!

Secondly, make it a point to consistently check your floors, especially the areas behind sofas and beneath driver and passenger seats for dampness, as well as the insides of every closet, including the ceilings.

Third, use your sense of smell to tell you whether there is water lying in your coach. Mildew and mold have very distinct odors, and you need to pay attention to them if the odor in your coach is “off”. A well maintained motor home or camper should always smell dry and be free of odors.

Fourth, if you have windshield curtains, keep them away from the glass as much as possible so that condensation does not touch them. If they are kept dry, there is no way they can become stained.

In addition to these steps, when using your unit do everything possible to keep humidity at a minimum and condensation from forming. You will find specific directions for doing this in How to Prevent and Repair RV Water Intrusion Problems, so make sure that you take the time to read it.

A Final Word Of Caution

No matter how fancy or expensive a recreational vehicle is, sooner or later, it's going to leak.

When it does, those ugly water stains will appear, and it will be up to you to clean them and check for hidden problems as soon as possible.

Early detection translates into easy and inexpensive cleaning. It will also prevent the possibility of expensive and sometimes dangerous problems.

Do not delay. Now is the time to examine your coach.

Do you feel this information will help you to prevent and repair RV water stains and damage?

  • Yes
  • I'm not sure
  • Only if I catch them early. After that, I think it will be too late!
