Removing odors

OdoBan from Wal-MArt or Home Depot. Removed shrimp odor from a freezer after a power failure.

I too have heard good things from the ozone generators. I have a small one that sits in the fridge and it seems to do a good job. Either that or we just eat the food quick enough.

Febreeze makes a shampoo for carpet cleaners now and it works pretty well. Ours had a bit of a lived in odor as it is old and when the PO re-carpeted, they just put new carpet over the old. After cleaning every square inch I could get to with the carpet cleaner, the smell is about 93% gone. I may try again with a small amount of vinegar added to the cleaner or maybe just see about getting one of those Ozone machines.

Companies like ServePro, use ozone generators to remove odors after fire and flood damage. Used properly they will remove the odors so they do not return. I have used them on new construction commercial buildings to remove the odors from paint and other things that may affect people with allergies.

If there is a musty smell then I would assume there is a water leak somewhere that has gone unnoticed. I would not assume it was just because it was sitting closed up. With that said...

You really don't need a professional steam cleaner. I used them on my MH and ended up doing a better job myself with a Hoover spin brush carpet cleaner.

Where I really made a huge improvement on my current 5'ver was after shampooing the carpet I went over it again with hot water, but this time had added 5oz of bleach in the gallon of water. This worked wonders.

You can heat up the oven and splash it with some Vanilla Extract to see if that helps with odors. If all else fails, your rig will smell like freshly baked cookies at least.

A used car dealer would remove order in cars by putting a bail of hay in side with window up for one week.

Rent a Ozone Generator, plug it in and let it run for a couple of days. Repeat if necessary! I used one in a stinky van that I bought. It smelled like cat urine. The smell was gone in one day and never returned! Ozone will kill any smoke odors and the odor doesn't return!

New carpet, dinette set reupholstered with new foam, and washable throw rugs on linoleum portions ... resulted in smell gone.

Now as to bathroom smell, we use Pine-sol after each black tank emptied and ordered a new vent cover (which spins), and now bathroom smell gone.

Professional carpet and upholstery cleaning. Truckmount only with steam. Also painting will remove a lot of odors.

Cig smoke will be really tough, but you can get it out with a good professional carpet cleaning at toss all furniture, pillows, etc., as it will be in the inner cushion fibers. Be sure to also have curtains cleaned. You will still have a slight smell every now and then.

New carpet, bedding including mattress and Fabreeze, Lots of Fabreeze and Liver and Onions sometimes but that just made Liver and Onion smell, just as bad.
