My climate doesn t allow drying outside, takes more time but that ain t a problem.
I hate thing s that make live easier like a dryer, and they make your fresh wash take on a odour i dislike. Makes we wonder if it didn t waste the freshness of the Wash-machine. I used to hand-wash in my youth wonder if it smelled as bed as i imagine.
Lets hope not. Once a while io bring my wash to my Mom, and she would wash/ dry/ fold it. This washes smelled so fresh, like a sea-breeze. So eventually i got my wash routine as should. Got Wash-machine and despite trying different Detergent s. Even the most expensive Ecological powder s/ liquid would not match my Mom s:
Sea-breeze.
Well i was stuck, i have the Nose ! still have a very developed maybe overly working apparatus on my face. It s quite large so it should be working imo. Why have such a pronounced 'Smell-Organ' if it doesn t work. She shared me her magical wash routine creating that sea-breeze effect.
She used Neutral, a detergent with out a Perfume, its for people that have in-tolerances. My Mom has ? What no Perfume ? What was her secret ingredient.
We hung the Neutral wash outside on a line between two Apple trees.
When i got it of, the smell of Sea-breeze was there. She lives about 40 km from the Sea. In the dirty polluted city air, all air polluted i live near sea and it stinks here.
But it was the clue, her Perfume the same as mine, Sea-breeze not only dried my wash. It seemed revived by it, and overpowered pollution if there.
What you do in live taking care of your parents amazes me. Do you have help ?
Over here you have several system s, like Home Care and District Nursing.
There prime healthcare dr., isn t he involved ?
When i imagine myself under insomnia circumstance s doing what you do seem s.
To much responsibility for one person imo. Read s like you are alone taking care of yourself, Parent s, Dog, House and keeping up a job.
If something happens to you, who takes care of you and take the care momentarily over, if you are not able to. I wouldn t like other s at that point invading my system. Interfering, is very irritating when i haven t slept OK a few week s.
but in reality in your situation DIY is so heavy a burden, you shouldn t be doing this alone. any people around you got good contact with who might be able to help you.
Friend s or Family/ brother s or sister s ? I am the sole child, but a relative or good friend would be my first thought. In Netherlands there is
nursing and care at home (district nursing)
