We do take off the covers and wrap the cushion in a trash bag, put cover back on, prespray-clean-dry.... Take bag off the cushion a day later... The good thing for us is most of the time we get the cushions back in-plant and can take the appropriate steps (not rushed on the job site) to correct the problem...
Not always practical Nate. And most of us clean on location.
Also when taking the cover off the foam/down cushions, one takes the risk of damaging the zipper. Some of these zippers are not made to last. So there's always risk, no matter what.
Again, we always hear and emphasize all the potential disasters. And of course, it is important to know in advance what to look for, be cautious of and how to adjust the cleaning technique.
However, by now, I've possibly cleaned hundreds of pieces with down filling and so far never had an issue. So Scott's advise is a good one.
