Yeh, you know what it's like Ian. When doing intricate pleats, pelmets etc you've got no choice but to do it by hand.
We did have a sahara but was disappointed in it's performance. The usage of fluid was a lot even after reclaiming used fluid & filtering etc, it wasnt that great. I know of quite a few cc's who only do the terry towel method and swear by it. I know I do!
Its the pad pressure involved that we have found that removes the grime as opposed to just the suction of the bristled handtool on the sahara, which gives us better results.
I have considered using HWE CFR, but back off not only from fear of shrinkage (I know I know, ...shrinkage test will determine and all that LOL), but because 99% of the time the curtains are'nt exactly grubby that need HWE.
Cheers
