In the UK most people have rotary clothes lines. I have had one all my married life (32 years)including a time with 2 babies both in diapers. You make a hole in the lawn or preferably patio/decking (clothes dry quicker than on the grass way because of heat reflection)- which is obviously less straightford but worth it, insert the tube included with the dryer & pop end of dryer in. Dryer is then removable if you have visitors & want to look posh. I have a neat cover for mine which pops over the top when it's folded & keeps it dry & safe from children. I am not very tall - 5'3" & whole system could not be simpler. The dryer spins round when windy getting clothes nice & dry & you can dry a heck of a lot at anyone time. Last weekend I dried 2 washing loads at once, although it was 40 degrees F but windy so laundry, including towels got nearly dry & I now have quite a small version of the dryer.Just popped some laundry in the dryer to finish off. The shirts soon dryed indoors on hangers & did not need ironing. PS I use plastic pegs which do not mark. I have a lot of birds in my back yard & encourage them with a bird feeder but any bird droppings on laundry vvvv rare as they do not seem to like perching on the rotary dryer.

I agree with aamassther, sounds like it may be rust. If it is rust, keep in mind that is set by chlorine bleach. There are products that remove rust, like Iron Out. I had a similar problem years ago when I lived in an apartment. I noticed the rust stains on light colored clothing. Apparently my water heater was on its last leg, and was adding rust to the hot water. Unfortunately I didn't realize that was the problem until I found the water heater was also leaking. Try taking a white cloth and holding it under a stream of hot water from your sink so the water flows through it - after a minute or two, check to see if there is any orange coloration. If so, you know that there is rust in your water supply. If not, then maybe something metal is logged in your washer drum and rusting. If something rusty was in the pin trap of the washer, which is before the pump, I don't think the rust from it would reach up into the wash drum. Good luck!

There's a company in Oregon that sells patterns and all those sorts of fabrics.I'm sorry the name escapes me now,but perhaps someone else knows what i am speaking of.It seems it was called Green-------- something or other. Kathi

I think things keep getting lost in translation since I can barely speak English (non-native/don't live in US). "I rewashed every clothes and bedding sets with FL to test its capability." (from my post) "No. I'm using only he detergent (persil or tide, both liquid) after the switch. (But before the switch, I was hammering down the powder detergent)" (from my previous comment of 25 JAN) "I forgot about the fact that I had been using not only persil but also tide pods (spring meadow) during the rewashing process. I did total 30 loads of rewashing back then, and one thirds of them were done by tide pods (the dosage was usually one pod but sometimes two pods)." (from my last comment of 28 JAN) "The rewashing process" on my last comment indicates the FIRST rewashing process (which I did to test the capability of new machine). So my last comment means I used not only persil but also tide pods (on the contrary to my previous comment of 25 JAN) during the very first rewashing process which was taken before I figured out something went wrong. After I realized something went wrong, I've suspected built-up detergent is causing the problem, hence I started to do the SECOND rewashing process (to remove excessive detergent build-up). And of course I only used none to very little detergent (10ml of persil liquid for small load, 20ml for large load) during the second rewashing process. This is what happened in chronological order. 1. 2015 summer - I started doing laundry for myself with non-HE TL. I didn't measure the detergent at that time (usually pouring down a cup of detergent), but there was no problem for the full six months. 2. JAN 2016 - I bought a FL and rewashed most of my clothes using persil/tide liquid or tide pods (dosage was usually 3-5 Tbs or 1-2 pods for full load which is recommended amount). 3. Within a week, I got itchy and rashes appeared all over my body. On the closer examination, I found my towels were much stiffer than it used to be once. And I noticed a lot of white particles were coming out when I put them in hot water. 4. I've suspected built-up detergent is causing this problem, so I started to rewash them. After I rewashed one quarter of my clothes again in various ways (dosage was somewhere between none to 0.6-1.3 Tbs), I found machine-rewash/rinse doesn't do many good (they still released white particles in hot water). 5. I posted my post (25 JAN).
