I left the dosing ball in the drying cycle of my washer-dryer (on the 'high' heat programme), for about 30 mins.
The dosing ball has come out a bit squished/bent.
The instructions say you should always remove the dosing ball before the drying cycle.
Would you re-wash your stuff (in this case DC's towels) out of concern that they might now have invisible residues of melted plastic on them?
