Home Depot has a product I used called Mold Control. Take out everything including cushions.
Wear a mask and heavily spray everything inside and out including any wood items. I sprayed the fridge
, stove, oven, keep the oven door open. Do the ceiling last and work your way out.
Spray the carpet well even tho you are removing it.
Make sure all windows
and vents are closed when you are finished.
Spray and saturate your cushions, both sides and let them air dry in the sun.
Give it a couple of days and then air out the trailer and repeat the whole process.
The spray container states not to clean off as it leaves a protective film but I have CLD so masked up and rinsed everything off with many changes of hot water.
The carpet got two darn good shampoos.
I unzipped the cushions, laundered them in warm water, twice, and hung them to dry in the sun. I let the foam dry from the spray in the sun.
It was a lot of elbow grease but no mold or mildew remains.
I have no idea what to do regarding the floor but have read lots of excellent posts regarding that in this forum. This late fall
the carpet in my Boiler is being ripped out and thrown out. We are probably going to put linoleum down.
