Is gram staining is a simple procedure?
Applying it is quite simple. You need to apply crystal violet for 2-4 minutes, rinse with water, apply Lugol's iodine for 2 min, rinse, apply 70-90% ethanol for 30 seconds, rinse, apply safranin or fuchsine for about 20 seconds, rinse and it's done. It looks like a lot, but this whole precedure is about adding stains and waiting to rinse them. It may work even if you mess up with the time at some point, not much can go wrong.

What are the differences between permanent press delicate and regular washing machine cycles?
From my laundry machine's operating manual: Regular Cycle Can be used for most fabrics. It provides up to 15 mins of normal wash agitation. There is spray rinse during the first spin, followed by deep rinse and a fast spinal spin Perm Press Cycle Can be used for cottons and blends with no-iron finish. Provides up to 12 mins of normal wash agitation. There is a cool down rinse to reduce wrinkling in the first spin, followed by a deep rinse and a fast final spin. Delicate Cycle Provides 8 mins of gentle wash/pause action. There is spray rinse during the first spin, followed by a deep rinse and a fast final spin. I guess you should refer to your own machine's operating manual to know the exact times but the rest should be the same.
How do you get permanent paint out of a dress quickly?
turpintine. Well, I know how to get Permanent Marker out of clothes: If you have access to ethanol (perhaps in your school's Chemistry lab), make a 95% solution (95 parts ethanol to 5 parts water) & apply directly to the stain. Rinse thoroughly with water and wash as usual. If ethanol is not available, you can try spraying hairspray directly (& heavily) onto the stains before placing uniform in the wash. Hope that helped!
