No I have actually found it to be easiest. I have a whole bunch of them and as they get soiled I switch them out for clean ones. When I have a whole bunch of them, I throw them in the washing machine with color safe bleach. I run my throw rugs and dog beds in the next load just because herp stuff is pretty rank and I do not want to chance getting residue on my other laundry. I only use the home depot kind though because lowes' carpet has black backing which is non absorbent and it makes a mess in the washer/dryer.
