How can I fix black mold stains on the ceiling of my motor home?

Hi Chuck Bob Worthing UK
Bicarbonate powder used in cooking (not baking powder) mix level desert spoon of bicarb in a litre of warm water it kills the spores but stains remain. ( I also use it to clean the fridge/freezer in caravan and house)

Wait until its perfectly dry then hand paint with paint roller or brush. First check with local motorhome store what's the best paint I favour water based is has less odour, repeating myself wait until it is really dry or the paint will peel off.

What is between ceiling and roof? Might not of dryed out fully, takes a long time, so mould will keep coming back.
I find just plain bleach works for mildue, BUT can damage surrounds, depends on what surround material is. I use it in a spray, spray on see what happens, wipe off, wash off. Works well shower areas as well.

If not dryed out fully, you need heat in the motor home, for some time, to dry out, remember, you apply heat, but moisture has no where to go in a closed area. you could use a dehumidifier, which will condense the moisture to water in a tank
