The more I surf other peoples blogs, the more I read negative comments about this – surely there must be more positive ones? I'll kick off this debate with my own findings. I have only ever used non-bio so comparisons may be different with bio products. Also, I have only ever used 'whites' rather than 'colours' products.
Neither commercial nor frugal wash liquid completely removed the greasy marks/stains on their own. I found I needed to either lightly scrub or rub soap/frugal liquid/washing up liquid onto the garment before washing to get it completely clean.
I also used to find when ironing armpit areas, that although the clothes appeared to have been cleaned, when the hot iron got on this area, it brought out a slight smell of sweat. Now, I never, ever have this problem.
Loss of colour/whites going grey:
I'm probably not the best one to comment on this as I have said above, I have only used 'whites' products. As most people know, white products contain whitening agents, which frugal liquid doesn't. So some of my whites have changed colour slightly but not too much. The only greyness I have noticed is in my beige towels which get washed with dark towels so that may be the reason.
My dark brown towels have lightened slightly, but they would for me anyway for the reasons mentioned above reference 'whites' products.
As soap is half of the main component of frugal liquid, it naturally leaves a scum on surfaces. The washing soda or borax helps remove this, as does the vinegar conditioner at the end. If you don't use vinegar as a conditioner, maybe that could also be the cause of greyness.
Damaging or clogging up your machine:
I have been using this product for 5 months now. My washing machine is still lovely and clean and sparkling with no smells. When I used just non bio products, I got a horrible smell after a few months. When I remember, I do a washing soda boil wash at the beginning of each month. Previously, this did not always remove this smell. Now, I never have the smell even when I forget to do a boil wash.
Those are the main complaints I have found. Anyone come across any others?
I have not managed to source Borax so I would like to try that instead of washing soda. Does anyone use Borax, is it different to washing soda from a cleaning point of view?
My washing now smells of sweet, fresh air as opposed to an overpowering commercial chemical smell. If in the future I find that my whites do go dingy, I shall give them the occasional wash with an appropriate product.
