Cement like nappies

That doesn't sound normal

What's your washing routine?

yes tell us this

i wash every other day, do 2 cool washes then pop in a teaspoon of powder and wash on 30 then rince 3 more times, then spin them then either out on the line or tumble

Are there any suds in the machin on the rinses?
What do they feel like when wet?
Do you have hard water? Maybe try a bigger dose of powder...

If you want to post one to me I can try washing it here to see if it's you machine causing the problem? @laceybat

no sud at all when washing yes hard water. they feel a bit stick but soft

I wouldn't have thought it would be a soap residue, as you would know about it when using them, when I had that with mine they developed a bed ammonia smell when wee'd in. Perhaps try a wash with apple cider vinegar in the fabric softer drawer?

I think you need to use more powder in the drawer. Do you use a water softer such as calgon? Hard water areas need more detergent to gets items clean.

If you live in a hard water area then 1tsp of powder is nowhere near enough. I would probably also try washing at a higher temp I think. I use a full dose of bio powder. (usually Bold 2 in 1 as that helps keep them softer) I cold rinse, wash at 40 (sometimes at 60), then 2/3 rinses at the end.

i will try all thats been said on tomorrows wash

we have hard water here, and I use a full dose of powder. But I do have a top loader too so there's a massive amount of water running through them.
