Remove Mattress Odor With Nok-Out


Stinky Mattress Keeping You Up at Night?

Mattress Odors are offensive, and often difficult to remove. But, Nok-Out is the solution! Nok-Out will always remove the odor, if it makes direct contact with the source of the odor. Direct contact with all of the stinky stuff is required for Nok-Out to do its work. Given all the  layers that comprise your mattress, this may mean you have to think carefully about how to get Nok-Out to go deep into the mattress, where it can come into direct contact with the smelly stuff. Consequently, it is important to identify the site of the stain or contamination as far as possible, and to concentrate your efforts at that source. If you follow these guides, you can safely and permanently remove mattress odor, so you can sleep good again!

Start With a Good Vacuuming

Your mattress is likely to be a place where dead skin cells accumulate. Add sweat and other moisture and you get a breeding ground for little mites that are mostly invisible to the naked eye. A good vacuuming can help take away the food source for those mites. Many Vacuum cleaners have a little “beater’ attachment. If yours has one, use it to help loosen up and get rid of the dust and dead mites clogging the surface of the mattress.

Procedures to Remove Mattress Odor

If the mattress is one of the newer, pillow top kind, and the site of the odor-causing agent is rather new, the odor has probably not penetrated into the sub mattress stuffing, and will be easier to remove. At the site of the odor, spray enough Nok-Out directly onto the contaminated spot so that it is wet. Allow to ‘wick’ into the outer edges of the stain. Let it sit for up to 5 minutes. Sponge dry, and allow to air dry before placing clean sheets on the bed. You may want to use a fan to speed the drying.

If the mattress is an older type, careful saturation of the site is required, following directions above, but covering a larger area, and allowing up to 10 minutes to ‘wick’ into the surrounding area before blotting and allowing to dry.

Mold and Mildew

Mold & mildew poses a different issue, but the removal process is basically the same. If it is simply a surface problem, simply spraying SNiPER on the site of contamination, allowing to air dry will kill the mold and is usually sufficient to deodorize as well. SNiPER is a mild cleanser as well as an odor remover, and fungicide. However, older stains may not be removed entirely. Remember that SNiPER is our fungicide product! Nok-Out will remove any odor, but it is SNiPER that can clean mold.

Other Odors

Odors which have permeated the entire mattress, such as molds, smoke or tobacco smells, are much more difficult to remove because of the larger area of contamination and because they may have penetrated deeper into the mattress. In this instance, spray the entire mattress, top, bottom and sides carefully, spraying seams, buttons (if any), and all corners, or crevices thoroughly. Allow to air dry. Do not blot away any excess. The odor will be immediately removed, but if in a few days, a smell returns, it is because the odors have leached from inside the mattress to the top. Another application is in order should this occur. Through this process, all odors will be eliminated.

The Odor That Keeps Coming Back

You may find that some odor keeps returning. Usually, this is because the odor source has penetrated deeply into the layers of the mattress and Nok-Out did not penetrate deeply enough to come into direct contact with the source. This is a tough case because we mostly don’t know what is beneath the surface material of the mattress. We do know that there may be many layers.

If some kind of mold is growing deep inside the mattress, then SNiPER needs to go that deep down into the mattress as well. The solution here is to dilute SNiPER by 3 parts water and literally our in on the area, allowing gravity to pull it down deep into those layers. This requires several days for drying so do not pour so much liquid onto your mattress and expect to sleep on it that night.

Nok-Out is a safe, non-toxic cleaner that can eliminate mattress odors on contact with the odor source. Follow these instruction so that you can sleep well again!

Removed All The Feral Cat Urine

Sniper has been AMAZING. I was able to completely remove all the feral cat urine scent from the carpets, mattresses, clothing, and toys. It worked beautifully and left no smell, no fumes, and didn’t leave any discoloration. Sniper is now my cleaner of choice and I use it everywhere to clean and sanitize as well as freshen the air. I even use it in my daughter’s gym shoes and soccer bag. Thank you so much. Seriously the best product on the market.

Cats Get Old!

Cats get old. Things happen. Nok-Out was recommended to me by a friend in another state. I Will never go to the pet store again to try any other product. Nok-Out is IT! I told my Veterinarian about it. I love how fast it arrives after ordering. I ordered three times because we are still working on issues, but at least the house doesn’t SMELL! Amazing product. THANK YOU!

Completely Eliminate a Horrible Smell

Mary Hunt introduced me to Nok-Out years ago and I am still amazed at how it can completely eliminate a horrible smell.

Yesterday I hosed some dust off a plastic laundry basket. I left it outside to dry for a bit and then returned it to the garage.

A few hours later I walked into the garage and the entire place reeked of cat pee! I did not realize that the neighborhood tom cat had come by and sprayed my basket. It was so bad that I was ready to trash it, but I thought I would try to spray it down with Sniper first. I doused it liberally and left it overnight. Ta Da! Absolutely no smell this morning!

Even after all these years, I am still amazed every time your product works on a smell as terrible as cat spray!

Thank you, Ted!

Christmas tree and Raggedy Ann

We have an artificial Christmas tree that’s still gorgeous but old. Putting it up always bothers my asthma and irritation from getting scratched is not pleasant. Last year I sprayed the tree and the “old tree” smell disappeared. I had purchased Sniper on Mary Hunts advice and it really took care of the basement (moldy) smell! Great! My daughters vintage dolls with cloth bodies had spots of mold or mildew, these are dolls my grandchildren play with. Oh my goodness! Sprayed the doll’s bodies and yarn hair, and the next day they all smelled great, moldy spots gone ! These dolls were over 30 years old and now look soooo good! Would recommend Sniper for other uses, too. Doggy rug smells gone! Smelly shoe odors gone. Grateful to Mary Hunts column for letting us know. 😊👍⭐️

“Nok-Out Saved My New Car!”

Thank you for creating such a great product. I would and will recommend this to everyone I know. My son left raw meat in my car for 4 days and I thought that my new car was ruined, but after talking with you and using the product, I can now get in my car and the only thing that I smell is a clean, disinfected smell! Thank you for saving my new car!

Sniper Removed Old Water Odors, Mold & Mildew

I have been using Sniper in the Offshore oil industry as both a disinfectant and a deodorizer for years. It has eliminated old water smells of toilets and bathrooms not used in a year where the water sat and molded mildewed and stank. As well as being injected into our old quarters ac vents to prevent mold buildup. Always worked better than anything comparable and well worth the price.

My Mildew Stain Disappeared!

I brought in the plants for winter and when it was time to move them back outside in the spring, I had a mildew stain on the carpet. I received my Nok-Out Carpet cleaner and sprayed the stain and let it sit for 10 minutes. When I returned to scrub the stain it was completely gone!! Woo hoo!! Thank you, Mary Hunt, for introducing me to this wonderful product!
