Can anyone suggest the best way for cleaning the speaker cloth of my Cossor?

I did a very similar cloth to this on a Cossor 501 (or is it 500 - the Bakelite one). I think I soaked mine off the back board (applying water sparingly and peeling back slowly, as I remember), washed it by hand with some washing powder - and it came up like new. I was less successful getting it back 'tight' on the board but I have been loathe to risk taking it off again for another go!

It's hard to get much improvement without wetting it, and if you're going to remove and wet it, soapy water may work fine, but you might wish to use stain remover powder, which you add to warm water and is very effective. I use some from Poundland called 'Wizz Oxy' which is widely available.

Poundland now sell Vanish stain remover powder:

You can buy spray stain remover, but it's meant to be sprayed onto fabrics before they're put in the washing machine.

One way or another, it's hard to get an effective result without wetting the fabric and wetting means some shrinkage. Best to not let it soak - remove it and damp it dry then let it fully dry at room temperature, rather than for example, ironing it.

When you've glued it back on the board, it might help to tighten it by using a hair dryer.

Hope that might help.

With respect to re-gluing back on, (After washing or if replacing the cloth) use a spray on iron starch on the cloth, and use an iron at low heat, this will produce a flat cloth ready to glue, apply glue to the board, place cloth on board and use a hand roller to finish off.
