Hi Stephen:

I say this with much respect to Fred. I do mention to my clients the jury is still out on this. 

The only reason I suggest it wouldn't weaken the sealer is being in the carpet cleaning business for twenty years. We use steam irons on different stains and for the acceleration of bleaches. Steam in these cases where you leave on top a terry cloth towel for 15 to 30 seconds at a time is still very slow to remove, re-liquify things for removal. In the case of these cheap steam mops they buy at a store sliding them over the marble surface at 1 mph I really don’t think it would weaken the sealer. I own a Swedish steamer that cost $800.00 and found it was slower in removal of stains than a steam iron. 
Just my experience.

Steam has a temperature of 212 F which is close to the melting point of some fluroalphatics..so I would not recommend it.

what type of sealer are you asking about? a topical coating or a penetrating sealer?

Most of our clients use those without a problem. I personally think that they wouldn’t harm the sealer.
