Left these out in the garden since last Summer and they are now looking grey and grubby. I've washed them best I can but they still look bad.
I also tried to rub them down with fine wire wool but that just roughed-up the surface of the plastic without removing the ingrained stain.
Any ideas or do I just chuck them and get new ones? They were kind of expensive and there are 4 of them so don't fancy the latter option.
Was thinking about giving them a wash with a concentrated sodium peroxide solution.
