Cleaning removable sofa covers

You can buy dry cleaning kits from lakeland which you use in your washing machine.

Try carpet dry foam shampoo it should work

Deeply grateful to all the help here and some I garnered elsewhere on the web. I have a G plan Chloe sofa and chairs which I bought on eBay a few years ago and love. Can't find any fabric info on the chairs and the only cleaning advice is on the G plan website, which basically says 'don't do it yourself'! I had it professionally cleaned and the guy used a machine which sprayed water and soap on it and sucked it out again. The sofa cushions now needed cleaning but it seemed a bit OTT to get him back just for that. Having read everything on here, I did the following:

Carefully removed the covers, folding them back like peeling a banana and then rolling so that the zips didn't snag the fragile netting holding the yellow foam.

Zipped them back up again and washed in wool cycle, ie short wash but spin was quite high.

Someone suggested they shrink as they dry, though, with hindsight, I don't think mine would have done, so I put them back on the cushions as soon as they were out of the washing machine, putting as little pressure as possible on the zips so as not to break them.

I then left them overnight on my wire airer. They are stunningly clean but don't actually make the rest of the sofa look dirty (a danger if you do a long wash, says specialist cleaning man). I doubt I'll get professional cleaners in again for the cushions, though when I get the cream carpet cleaned again, I might negotiate a price for the non-removable bits of the sofa.

If your cushions are the white modern foam, search the internet for how to shrink them using a hoover! I was very disappointed that my foam was too old for me to be able to play that particular game!
