should be safe, I take it you have indetified it correctly, if so then there is very little risk of shrinkige, do not over wet, plenty of dry strokes (can never have to many) and test it for colour fastness first, but generaly 1 of my favourites to clean always get good resutls, although it may smel of wet dog when you have finished, some people love it others hate it. !!! HWE is a good method imo
