Half chap help.. My chaps are slippery as ice!?

This is going to sound crazy, but if they are not an expensive pair, and they are mostly suede leather then you can put them in the washing machine... After a couple of months of wear my cheap half chaps go from suede to smooth because the horse sweat and dander just gets into them. Put them in an old pillow case to protect the washing machine from buckles or clips and then just put the washing machine on normal cycle. If you have leather detergent it helps but it's not essential. I've been doing that to my $30 chaps every 3 or 4 months for the last 2 years and they've lasted great, they look almost new when they come out of the machine.
