How to Clean Washing Machine

SuperShock Home Recipe Formula


I had to send this email to thank you for helping me remove the smell from my washer.  We live near the beach and I assumed that it was inevitable that my washer and towels would always smell. I even went out and purchased a new top loading machine and got rid of my front loader thinking I would not have odor issues. Wrong! I scrubbed my machine with borax and dish soap and ran the machines clean cycle 3 x and it could not compare to one round of the shock treatment. There is still a slight odor but I have received my Techno Fresh and have begun adding it to my wash.

Thank you for the great information on your website. I tell all my friends to check it out.



This page explains how to clean the machine and contaminated clothes so that they are almost like new

SuperShock is a special, extra strong, vinegar based, cleaning and disinfecting treatment.

This vinegar based method works better than anything we have found.

This recipe uses common household materials to clean the machine. Vinegar, dishwasher detergent and regular salt of any kind.

Do not add TechnoFresh® for Phase One of the shock treatment.

 It doesn't work that way.

While TechnoFresh would in fact clean out the machine by itself, it would take a few months and use up a lot of Technofresh.

That is because it takes a long time for the TechnoFresh to penetrate the gunk layer that has built up.

The SuperShock cuts that time significantly.

This cleaning method is more effective than the tablets or packets you have tried in the past.


Phase One:

Step #1. Add  2 ounces of  DISHWASHER detergent ( NOT the liquid for hand washing in the sink ) to the  tub even if you are using a gel or liquid form of this  detergent). You don't need much. It adds ions and helps the plumbing rinse sparkling clean.

 Any brand of dishwasher detergent should work. If you have the two chamber packet kind you need to borrow some regular stuff from a neighbor. You paid a lot for that special packaging and extra chemicals so you shouldn't waste it on these shocks.

Note:  If possible use a powdered dishwasher detergent. Use the cheapest brand you can buy. You won’t pay for fancy rinse aids, enzymes and other stuff you don’t need that might hinder the cleaning.

Step #2.  Add 4 ounces of regular salt on top of the Dishwasher detergent. This adds extra ions to help lift off the scum.

Step #3. Place a large load of rags or old towels in the drum.  A really large load will increase the amount of water used resulting in a higher water line in the drum and it will also increase the wash time which will help a lot. Don't worry, the vinegar smell will rinse out before the cycle is over.

Step #4. Pour the one to two gallons of cheap white vinegar onto the old towels / rags in drum so they are well soaked (read note 1)

Note 1: If you pour the vinegar directly into the drum of the machine, it will be pumped out at the beginning of the wash cycle. The machine thinks it is water left over from the last load so it is a good thing for it to pump it out. So, you have to trick the machine by soaking the rags/towels with the vinegar.


Note 2: Two gallons of vinegar seems like a lot. It really works though. Use the cheapest vinegar you can find. To clean effectively, you need to offset the alkali nature of the detergent residue in the machine. Because vinegar is weak acetic acid you need lot of it. More than two gallons would be a waste though. Also, for any follow-up shock treatments (every three or four months)  you should only need one gallon or less. Compare the total cost of shock tablets or other products to the fact that this method actually works....

Step #5.  Run load with the longest and hottest water setting.

Note:  If you minimize your detergent use you may never have to shock again. Well not ever, but some customers report year long periods where the shock was not run and everything was fine



Remember, you are trying to remove / dissolve the soap and scum off of the walls of the tank and plumbing.

If you have been using excessive amounts of detergent and softener, there will be a large buildup. It could take up to three shock runs.

Click Nasty Problems for Examples

As this gunk is removed, you might find that the smell could even be increasing between shock runs

If so, you are using way too much detergent

The shock exposes the anaerobic bacteria slime growing on the decomposing organic based material that is caught up in the underlying detergent film.

If the detergent layer is thick it will not all come off at once.

As the upper layers come off, the machine can start to smell like a dirty swimming pool or a fish aquarium that needs cleaning.

Keep running the super shock. The odor will clear up eventually.



This is only necessary if you had a really bad problem and the fishy odor remains but you have to stop shocking for a day or so because your schedule won't allow continued cleaning.

Do a chlorine bleach shock (1 cup in hot water load, absolutely no other chemicals no towels) to knock out the fishy odor if it arises.  

The chlorine cleaning effect will not last long.

If it smells fishy, there is still more of the contaminated biofilm to be removed.

You may also see flecks of black mold that has been loosened and is floating around the machine.


Some machines are really gross I have been told.

Really, you should go to the Nasty Problems Page to see what you are up against.

Some actually have had the drain lines plug with thick black goo.

This is way too much detergent and softener being used.

End of Super Shock treatment Phase1.


Minor Problems

If you have a small buildup in your machine and one SuperShock works to remove the odor, you can skip to the Phase 3 of this procedure.

In Phase 3, you can return to doing your laundry again using TechnoFresh as needed.

Others with a really contaminated machine and a lot of contaminated, smelly laundry should continue with Phase 2 of the procedure as you feel necessary

Phase Two:

OK, with Phase One you have minimized the amount of detergent film on the plumbing by running a very effective shock treatment.

Phase Two is intended to continue to disinfect the machine and any laundry that smells by using double the TechnoFresh for these loads.

Add one full ounce - rounded capful/scoop (roughly) of TechnoFresh® to the machine.

A third of it sprinkled on top of the detergent in the dispenser (liquid or powder) and the rest directly into the tub before adding the laundry.

Use this full amount for every load you wash for the next week or two until you feel confident the odor is really controlled. 

During this time, rewash all of the clothes and other laundry that have been smelling.

Use a minimum of detergent and the hottest water the laundry can stand.

It will accelerate the effect of TechnoFresh® .

Cold water works but warmer/hotter water is faster.


Phase Three:

Phase Three is just your normal laundry routine where you control odor week-after-week with TechnoFresh®.

From now on TechnoFresh will work its way into all the nooks and crannies of the machine and continue to sanitize it.

So, after the machine has been cleaned, the odor has been controlled, and the laundry rewashed to reduce recontamination, you can return to your normal laundry routine. 

This is where you use less than one capful/scoop in the loads in which you use TechnoFresh®.  

You only need to use TechnoFresh® in a few loads every week. See “Wash Schedules” button for details.

Place most of the TechnoFresh® directly into the drum before adding the laundry.

Most of it will go through the holes in the drum to the outer drum where the nasties are growing.

Also sprinkle a little on top of the detergent (liquid or powder) in the dispenser as your wash schedule dictates.

Use less in dispenser if your machine does not dissolve the TechnoFresh. Machines vary.

No matter which detergent you use, the TechnoFresh® will mix with it and create a barrier to suppress the growth of the nasties.


Remember, from now on, only use one tablespoon of detergent or softener in any load.

Or roughly enough to just cover the bottom of the measuring cap.

No kidding...

Increase only if experience actually indicates you need more.

You will be surprised how little you need. 

Do not believe the recommended amount on the machine dispenser !

Do not fill up to the first mark of the detergent measuring cap ! 
Remember: The build up of the material is the food source for the biofilm. Starve the nasties



Remember: These machines concentrate the detergent/softener at the surface of the laundry fibers so very little is actually required. Always start with 1 tablespoonful and increase only if you actually see a need. If you have a small volume washer don’t reduce to less than a tablespoonful because you need a minimum amount of detergent for the stuff to work.

A real savings if you play it right ...

Hard or soft water does not have any effect on the performance of  TechnoFresh®. They do have an effect on detergent and fabric softener performance as explained elsewhere.

These directions seem to have worked for a lot of people over the years so they will probably work for you. However, there may be instances where the problem is so tough the machine must be disassembled and scrubbed to remove the build up. Thankfully this level seems to be very rare.       ( We have been in business since January 2008 and I haven’t heard of a tear down being required by a customer yet.)



Tip: Pick an article of clothing that gets consistently dirty like T-shirts or kid's socks. Try to use the smallest amount of detergent that will still get these clean. If these are clean, then the rest of the laundry is clean too. If not, increase the amount until the articles get clean. In the end, you will get an idea of how little you really need to use. Any reduction will help your problem. This experiment is pretty much required to find out how much your family needs to use in its machine. This is the maximum amount to use in the future to control the odor.

Tip:  To help with the odor problem, you should try to stop using liquid softener (try vinegar - it works!). The softener sheets used in the dryer will tend to put a thin coating on the "dryness" sensor. It is a pair of metal strips inside the drum just under the door opening. Wipe these down with a little rubbing alcohol every month or two to keep the sensor contact with the damp laundry working correctly


Thomas, I want to Thank You for your extra help! IT REALLY DID WORK NO MORE ROTTEN SMELLING MACHINE! Now I'm trying to get the smell out of all my clothes. That is a really big job but it is slowly working. I had to do 4 shocks to the machine to get the smell out, I was beginning to think it wasn't going to work but thank goodness it did. The smell keep keeping worst until the last (the 4th shock treatment) was done and I could smell my washing machine without gagging. Thank You! Thank You! I'm so glad I found your product! Thank you for your help.


... I rewashed all my clothes with TechnoFresh and they all came out smelling clean the first time!

Thank You Again!



Hi there!

First of all, I 'shock treated' the washer twice, per instructions, with a ginormous load of towels. After this, I pulled the drain to empty the left over water and see what sort of gunk I collected. (it's often full of gunk) After this, I noticed I still had quite a bit of 'gunk' in the crevices between the gasket and drum. I decided to use the “gasket cleaning  paste” with the dishwasher soap and salt and used a scrub sponge (and gloves, and elbow grease, lol) to get the rest of the gunk OUT of my machine. It worked beautifully! I had tried to go after this gunk before to no avail (using baking soda, or Brand X product crystals, or just a sponge). I think the 'shock treatment' loosened it all up and the 'paste treatment' was just what I needed to get it all out. I am so very happy that my laundry room no longer stinks like death and grow.

Our washer really hardly uses ANY water, so I don't think much 'soaking' is ever happening when I've tried to clean it out in the past. I never see a water line of any sort unless I have added several gallons of water (like the Brand X product instructions say). Also, there is no way I can 'soak' a load since once you pause our washer, it drains itself and shuts off after a while. I guess it's a great safety feature, but not great for trying to access that gasket gunk.

I am so glad I found your site! I was just about to (begrudgingly) order more Brand X product stuff, even though it really was only doing an 'ok' job. I hope the NuFresh is better, but like I said, just these 'shock treatment' tips have been more than worth it.

My husband is a farmer and we have 4 boys, so you can just imagine the uber-dirty laundry that goes through that machine. Plus what household of 6 is ever without a laundry day, lol!

Thanks so much! And please don't hesitate to 'bug' me if you want more details. I've spent endless hours on this (damn) washing machine and I'm happy to share the adventure.
