HE Washer Cleaner

It is amazing to talk with customers at (my store) that are buying a new laundry set. They tell me that they have heard of the mildew odor problems from their friends and family. But they want to save water and heard these new machines do a much better job of cleaning. I always give them you website addreess as a source of learning the "Care and Feeding" of these machines. I hope it brings you some business


Cleaning Front Loading and Top Loading HE Washers

There are two ways of controlling the odor causing growth:

 Week to Week Continuous Control or  Monthly Shock Treatments

Week to Week Continuous Control Method:

TechnoFresh® Continuous Control Directions:

It is my site so I get to go first...
Add a little TechnoFresh® to two or three loads of laundry washed each week to help control odors of mold and mildew. Place the TechnoFresh® directly into the drum with the laundry and sprinkle a little on top of the detergent you use. That’s it!

What could be  simpler?


How does TechnoFresh® work?

TechnoFresh® works completely different from all other methods.(Patent Pending)

TechnoFresh® has two ways of attacking the odor control issue: 

First: TechnoFresh® works by penetrating the biofilm: the  bacteria, mold and mildew deposits, and then killing them.  The chemicals in TechnoFresh® are chosen to do specific things through the wash cycle. They work together better than than by themselves.

Second: In real life, every load will continue to deposit excess detergent that will be available as food for future growth. Nobody can measure out "just enough and then no more"  for every wash. There will always be a film deposited. TechnoFresh® mixes with this film so the growth of nasties of all kinds is suppressed.


TechnoFresh® is a mixture of salts that dissolve easily in water. This TechnoFresh®/water solution is then mixed in the machine with any detergent  product you choose to use

When TechnoFresh® and the detergent are deposited on the  plumbing together, the TechnoFresh® forms a barrier to growth on  the detergent film.

This is the continuous control part of the process.

Think of it as: The soap sticks to the plumbing and the TechnoFresh® sticks to the soap ... and forms a barrier.

What is the TechnoFresh® barrier made of?

TechnoFresh® is made of chemicals that are harmful to the nasties but still safe for people to use regularly in a washing machine.

TechnoFresh® contains materials that are used in commercial pickling and  canning to retard spoilage, fungus suppression in makeup, and sterilizing of wounds. All  these materials are on the FDA Generally Accepted as Safe (GRAS) list. These chemicals are approved for consumption in small quantities so washing with them presents minimal hazard.

TechnoFresh contains the active ingredients: Sodium Borate Decahydrate (Borax), Magnesium Sulphate, Citric acid, Boric Acid, Sodium Percarbonate, Potassium Sorbate, Sodium Benzoate

TechnoFresh® is safe for use with septic systems when used as directed. 

TechnoFresh can be used with aerobic septic system digesters, as long as the discharge does not go to a landscaping pond. The borax that is used as the carrier for the active ingredients contains boron.  It is approximately the same amount of boron if you used 20 mule team detergent to wash the load. It is a really small amount but it will accumulate over time in the pond. Pond organisms are extra susceptible to the boron.

Otherwise, I have not had any negative feedback regarding the use of these septic system digesters.


TechnoFresh® does not contain any fragrances. TechnoFresh® works. So, fragrances are not needed.  The laundry ends up with a fresh smell anyway....

TechnoFresh® will work in hot, warm or cold water. 

See the TechnoFresh® Instructions page for details.

TechnoFresh® really does work.

And to prove it, it comes with a money back guarantee!




Monthly Shock Treatment Methods:

These are some of the directions for the periodic shock treatments suggested by the machine manufacturers or service people:

Chlorine Bleach Treatment Directions:

Add 1 to 2 cups of liquid bleach to directly to the tub without any laundry in the tub. Run the longest, hottest cycle available on your machine.

Chlorine acts by burning the cell walls of the mold or mildew. The cells rupture and they die. This method only affects the very top surface of the mold or mildew buildup. It must be repeated as  needed. It requires an extra, large, hot and empty load .

While this method can be effective in killing the organisms it also attacks the seals and gaskets of the  machine. The amount needed to control the growth is much more than the amount needed to brighten laundry. So, the machines  are not designed to handle too much of this type of shock. See the Shocking Spiders Page for details. Chlorine causes some of this type of  damage when using this type of shock treatment

This is similar to the chlorine shock treatment used on swimming pools. Sometimes the water clears up but the walls can still be slippery. The machine seems clean but the smell comes back fast.

Chlorine will not help remove the residue on the plumbing. It only kills the nasties on the surface. The food (residue) is still there for the next time. The effect only lasts a few days. It could work if you if you do a lot of laundry and only have a minimal problem. However, we advise against using chlorine shocks to minimize damage to the machine.  It just doesn't work well enough to justify the damage.

Baking soda and vinegar treatment directions:

No, you don’t add them at the same time or you will get the foaming volcano effect seen in so many chemistry classes. But it could be entertaining!!!

Add 1 to 2 cups of baking soda directly to the empty tub. Add the vinegar  to the final rinse or softener dispenser without any laundry in the tub. Run  the longest, hottest cycle available on your machine. Baking soda will  increase the pH (slightly caustic) and vinegar will  decrease the pH (slightly acidic). This may affect the growth of mold  and mildew. Once again, this method only affects the  very top layers of the mold or mildew buildup. It must be repeated as  needed. It requires an extra, large, hot and empty load.

Maybe the baking soda penetrates a little under the surface of the  build up and then the vinegar causes it to bubble up and release the  gunk. Interesting scenario but I have no idea if it is actually happening. Maybe the manufacturers that suggested this know something.  But I really don’t know what it would be...

When you think about it, it seems that the baking soda would not do much. It is  the vinegar that does the cleaning. Some service people say  that it will take at least 1 or 2 quarts (or more) of  vinegar to be effective. This actually makes more sense than the baking soda combination and will actually work. However, you really need to try our SuperShock treatment

The TechnoFresh™ SuperShock page will give you our version of a super vinegar shock treatment that, in my opinion, is more effective than any other shock including the commercial ones. And, it only uses basic household chemicals to do the job.

Some people have complained that two gallons of vinegar for one of our SuperShock treatments is expensive. And, we suggest that up to three shocks may be necessary for a really contaminated smelly machine. Well, there are two things to consider. 1. You will have a clean machine and it may not take three SuperShocks to get it clean. 2. A service call will cost a lot more and might not be as effective.

The SuperShock cleans the machine and TechnoFresh keeps it clean.

Commercial Products:

Also, there are other products that are said to work. Two  I have tried are: Affresh, which contains an oxidizer, an acid and an awful lot of fragrance and is made by Whirlpool, and Pure Washer which contains citric acid and possibly salt and other materials (they won't say) from with a 60 day guarantee. Tide and Clorox have cleaner that is similar to Affresh in the way they work. 

All of these products create a strong chemical solution that is meant to remove the soap film build up that provides the food source for the nasties. They all will remove the build up to some extent, depending on the amount of build up in your machine. Any of them could be effective in your situation. Fragrance is used in case the removal is not effective.

See:”Shocking Spiders” for more info about shock damage to machines.TechnoFresh contains a very small amount of acid. This dilutes quickly and will not affect the aluminum of the spider. The buffering and builders in the chemistry of the detergent take control of the wash solution a few minutes into the wash cycle.

The Recontamination Problem:

The problem with any of  the shock treatments is that the mold, mildew, and bacterial slime continue to grow in the machine between  treatments. So, even if the monthly shock treatment is effective, you are still slowly contaminating your laundry as the build up of the nasties continues through the month again. In fact, because of the physics involved in “wetting” a surface, I do not believe that you can ever remove all of the residue. So there are nasty spots here and there ready to spread to the new residue deposited in future loads.




Everyone uses a different combination of detergent and softener. Everyone uses different amounts. All of the makes and models of machines have different internal designs.  So, no one method is the "correct" method to control the odors. To be the most effective  at controlling the odors, you should read all the pages of this web  site. As long as you understand what is going on, you have a better chance of being successful in the long run.

None of the shock treatments worked for me. Most of my customers have not had success with the shock treatments either.

TechnoFresh® will work when the other methods don't.

Did I mention TechnoFresh® comes with a money back guarantee?


As I mentioned on the Home page: Why in the world am I giving you the shock treatment information if it could cut into the sales of TechnoFresh®?

Well, I am an environmentalist. These HE machines really do conserve water and electricity, and I want them to be successful. 

Besides, I think you will come around to TechnoFresh® eventually, after you have to rewash a few loads of clothes because the smells  have come back before you got around to the next shock treatment.

By the way, TechnoFresh® will get mold and mildew odors out of clothing or any other washable materials if the other methods have let you down.
