how safe is it to use the bibulous paper? Won't it introduce something else onto the slide?

When rinsing a simple stain, is it best to hold the slide at about a 45° angle and gently rinse with DI water from the top of the slide, allowing the water to flow indirectly over the bacterial smear? Or is it okay for the stream of DI water to make direct contact with the bacterial smear? I've been taught both methods, so I was curious which technique is preferred.😄

I’m always scared that I overly used the decolorizer, I always doubt that most of mu smears are gram-

It’s not a coincidence that this video showed on my feed now. I’m doing microbiology lab and our school does it through labster virtual learning. Watching this here is really helpful!

our decolorizer is so strong that I have to rinse 0.2 seconds after I apply it.

This whole time I thought I did something wrong. I didn’t even put it under the microscope. I couldn’t see anything stained on the glass … but i don’t see anything stained on yours either until you placed it under the microscope
