If you know how to test for colour bleed and it is ok you can HWE it using lower ph products depending on what you have. Restoremate Bioclean, Solutions MPower, Prochem Prespray gold etc.. Use a neutralizing rinse if using an alkaline prespray, If you have done any training the basics of cleaning something like this should have been included. Agitate with a carpet brush rather than a crb to prevent pile damage. Treat it like a a wool carpet with a fringe. There are specific products for cleaning fringes too. Also dust is the biggest issue, so make sure you vacuum it well on both sides, vacuuming from the back well will knock alot of the dust out. With testing, dusting, relatively gentle solutions, careful agitation and quick drying with air movers you should be ok. There are exceptions to every rule but I would avoid "experimenting" on rugs like these as some can be worth more than you can imagine.
