I've changed the way I prepare poopy diapers for the wash quite a bit. When I first started, I was really scrubbing out the dipaers with a scrub brush even when it was just the runny, mustardy breastmilk poo. And I think those first cloth diapers did take a toll for all my scrubbing and are wearing out faster.
When my older child started eating solids and the poo became clumpy, that was a really easy clean as the clumps came out into the toilet and left little on the diaper. No scrubbing necessary.
However, that changed and now it is not so clumpy and more like peanut butter, and my second child now has the breastmilk poo. This would mean a lot of scrubbing and I don't particularly like cleaning this with my hands. So you might say I've become lazy in this area, but I found that it works!
I do absolutely nothing with the breastmilk poo. I put it directly into my diaper pail and wash it when it comes time. There is sometimes a bit of staining on the diaper, but that will happen whether you scrub or not. If I hang them out in the sun, that breastmilk poo staining comes right out. Mind you, with doing elimination communication with him, he doesn't often have poopy diapers.
With the solid foods poo, I take a wipe and scrape what I can into the toilet. I don't worry about getting it super well though. At times there is still quite a bit left on the diaper depending on how badly soiled it is. And I put the diaper directly into the diaper pail to sit until I wash them. The first time I tried this I was a bit concerned that I would find poo all along the inside of my washing machine, but actually I didn't. Sometimes if my child ate corn or grapes, I might find some skins on the side of a diaper, but they shake right off and were also adequately cleaned. And otherwise, they've come out really well through the wash.
