I usually soak my items in a bowl of water, then tip the water out in the garden.

I usually remove as much excess wss as close as I can. Then use running warm water at the faucet. I never thought about it clogging up the pipes. LOL

I usually just rinse mine off under the sink. I think that you would have to use a lot (tons) of the stuff before it would clog up your pipes.

I just do mine in my bathroom sink. I remove as much as possible first but with FSL being my favorite I have been doing it this way, i use very warm water and hold the design in my hand and run the water over it just till it is looking clean. I like mine to stay stiff so I don't rinse long at all. When I do finally make a doily or something I want soft I will soak it and keep rinsing and throw the water outside I guess.

On Fons and Porter they had a show about how to get rid of it. The gal on the show said to do it in a bowl of warm water. And dump it outside somewhere. Emlibrary.com Kenny has a video on this and he saves the left over water then puts the excess in a spray bottle. Equal parts of wss water and alcohol. The alcohol keeps fungus from growing.
Then if you want your FSL to be stiffer you just spray it on your design.
Hope this helps.

I always have a small spray bottle with water that I use for WSS. I must admit that I have not thought about the WSS blocking up the pipes, although I imagine that you would need a huge amount to actually block pipes.

It makes a wonderful starch for any fabric esp if you want to do cutwork.Disolve your torn off bits in a little water in a bowl then dip your pieces of fabric that you want to starch, hang out to dry and iron it while still damp.(organza behaves beautiful under the needle)
Can't be much in one design as you have already torn it away from around the design. and diluted in the rinse water. Similar to any sizing that is used on fabric.

Never occured to me you could block up pipes but have noticed it sticks to the sink if not cleaned off straight away. Lovely ideas of keeping some to starch other sewing projects!

I use a plastic wash tub and then dump the water outside in the yard somewhere, not in a flower bed. Also the temperature of the water rinse depends on the manufacturer. The brand I use recommends cold water. I think most say cool or warm. Nan in Texas

I remove the excess - which I keep to make a solution to be used as a stiffener - soak the article in a bowl, making sure there are no blobs of glue-y remnants, then empty the bowl in the sink and run the tap to further dilute the stuff.

I use the sink - it seems to dissolve pretty well and I run the water as I am getting rid of the WSS so I think it gets pretty diluted.
