[SOLVED] Clothes and chemicals don't mix After taking analytical this summer I notice I have many holes in my jeans... I spilled some Zimmermann-Reinhardt reagent on my jeans and I spilled it on my pocket of my jeans. I do know that it contains H2SO4 but I notice that everytime I was the jeans I have holes popping up...(darn it) I also worked with nitric, phosphoric, and of course hydrochloric acid this summer as well. Not only that, I also have other jeans which have holes popping up but I know I didn't spill any acid on them or base.... Why is it that washing causes the holes to be bigger and holes to appear where there was none? Is there a reaction with the detergent or is it the fabric is weak after the chemical spill or splatter?
