My father has a very strong sweat smell and is a heavy sweating person. I too have inherited this particular gene from him

I've been using anti-perspirants and all sorts of perfumes/scents. But the problem is, once I open my washing machine post washing my clothes, I can still get my sweat smell. Washing only removes the dirt from my clothes, but not my sweat smell. I've tried pre-soaking in liquid detergent before washing, adding scent softeners like
Comfort liquid, have tried soak washing, have tried different powder to liquid detergents. I still haven't got any solution for my problem. My washing machine has been maintained properly, have been run maintenance washes regularly using descale powder, so it is not a machine problem.
If you use liquid detergents and that Comfort stuff on a regular basis then i recommend you do a machine clean as detailed
here for your washer every month.
The way you're cleaning it descales it. It ain't the best way if you want to 'clean' the machine.
I've been searching online for a strong odour removing detergent, all I see are U.S based products. Is there anything in India that can help me with this problem?
1) Try
Dettol Laundry Sanitiser with spring blossom scent. The fresh linen scent smells too chemical for me.
Now the way this works is like fabric softener, in that its added in the last rinse. I put two caps in the fabric softener compartment per load.
Next bit is important. Once that last rinse begins you want it to soak for at least 15-20 minutes.
Regular front loader rinse cycles are too short and empty the water in like 5 minutes.
The reason for 15-20 minutes is its a biocide (quats) and needs time to kill the smell causing bacteria. This is why no detergent you tried earlier will work as it does not contain a biocide.
On my front loader i have a setting called Rinse hold. That stops the machine just before the spin cycle begins.
On recent front loaders i notice this setting has gone missing. Which means you need to pause the machine manually a few minutes into that last rinse cycle begins but obviously before it ends. Wait the required time and then let the wash complete as normal.
2) the second way is to use NaDCC tablets like these
Suma D4 tabs. They are used to purify water.
They are a substitute for bleach with the advantage they do not contain sodium hydroxide which is used as a stabilier to prolong shelf life of chlorine bleach like Clorox or Rin.
Use this product as it comes with accurate dosing instructions. Cheaper stuff from other companies that advertise 'chlorine tablets' do not mention dosing.
I use them to deodorise and sanitise kitchen sponges that develop a stink and get dirty. Best part is three months later the sponges still look like new whereas with clorox they would have disintegrated and required to be replaced. So these tabs are gentler on fabric AFAICT.
You will have to experiement with dosing for a given volume of water and do some testing so that you use enough to deodorise but not also bleach your clothes at the same time.
And you will have to pretreat them like soaking them for 15-20 minutes before putting them into the washing machine. More work compared to 1)
