We’ve been experimenting with low temperature washes and have discovered
that one of the limiting factors is that the powder just doesn’t dissolve
at low temperatures.

I could just buy liquid washing detergent but that goes against the grain
and it was suggested elsewhere just to dissolve the powder in some warm/hot
water first.

A trial with warm water really wasn’t very successful so it would seem
hotter water is required. Is there a temperature at which the enzymes are
denatured? I presume there must be but does anyone know?

What is wrong with a liquid detergent? The own brand lidl one used in
this household is OK in a cold water wash and advertised on the pack
down to 15C. It is also at least 50% cheaper than the equivalent well
known brands.

If thinking of a hotter wash then consider many(all) machines start with
a cold wash and then heat up the water. Starting with a hotter wash may
"set" some stains.

If you are watering down the detergent before applying it to the
detergent dispenser also watch out for the machine pumping out before
starting every wash cycle. If you are using a dispensing ball etc. this
may not be a problem.

Sounds like you're using the wrong powder, Try aldi, never had it fail to dissolve cold.

Careful. Not all creepy crawlies are killed with lower temp washes
I seem to remember a study that as the number of people cold washing
increased so did the incidences of fleas, lice, scabies, bed bugs etc.

If you have any of those washing your bed sheets etc. will not cure your
problem irrespective of how hot the wash. You still need to cure the
problem at the mattress level.

For other problems the temperature (alone) required for a kill may not
be too good for the clothes themselves. Again fleas also tend to live in
soft furnishing and carpets and then jump up to bite humans.

Yeah. That's why it was couched in such wishy washy language (careful ,
I seem to remember etc) .
I am not providing any absolutes merely stating that I remember
someone else claiming a direct causality between washing temperature and
beastie numbers.

I wonder how many more of these old sayings are being made obsolete by
powered hand tools.
