ick medication stain resin driftwood????

don't know about driftwood, but it will probably make the aquarium cauking and anything plastic in the tank turn blue/green!
if you don't want the discolour, then instead of buying ich medication try useing 1teaspoon salt per gallon of water for 2-3 weeks, and raising the temperature a few degrees. this should help, but I don't know what kinds of fish you have, so you may want to post that. some fish hate salt and it may harm them, but only 2-3 weeks of it to cure ich should do more good than harm.
salt is cheeper than meds and in my oppion works better
 
I agree with Paccula. Salt is the way to go. It is less stressful for the fish than Ich meds are and I can tell you it will not stain your decorations, silicone or tank lid. Also, you can still put your hand in the tank for maintenance without fear of breaking out in a rash. Also, It helps to understand the lifecycle of Ich and why salt and heat work to kill it, so I point you to an article written by Daveedka in the articles forum of Aquaria Central. Just follow this link and you will be enlightened and hopefully better prepared to fight this parasitic plague permanently. Good luck!
 
The ick medication will stain clear things like tubing and the sealant on glass aquariums. I know for sure that it wont stain resin ornaments, and its never stained any of my fake plants.
