While the stain does not cause any harm it is unsightly.
Rv ceiling carpet stain.
The fabric ceilings when they get moisture pull the coloring from the wood backing to the fabric and leave water rings.
Also with condensation you may get a 6 12 ring on the edge between the wall and ceiling.
Let it sit there overnight.
This works and is amazing.
We especially hate carpet on the ceiling and whatever the manufacturer wants to call it to us it is thin fuzzy carpet on the ceiling.
In the morning vacuum off the residue.
Cleaning stain from a rv cloth ceiling.
Bought an oil based primer and it took me 4 hours to thoroughly cover 4 sq ft of this stuff.
If the stains are not gone repeat the process.
Once the proper repair is made to prevent further water leakage the water stain remains on the interior fabric of the rv ceiling.
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.
The problem is carpet doesn t wear well especially when exposed to the kind of abuse an rv gets over time.
I ve dealt with my fair share of carpet but this is the first rv i have renovated with a carpeted ceiling.
At first i though i will paint it.
In most cases this will eliminate the stains.
Water stains that appear on the ceiling of an rv are cause for concern.
Cannot stand having anything that i cannot sanitize.
