Is this any good? out in the dark
a lively spark
invisable to the eye
sometimes above and high
a darker shade of grey,
she stalks her prey
she pounces on dinner
a likely winner
as swift as a bat
shes a black cat

what is the question.. you are more likely giving us something to read with no question

the best practice

1. keep your workspace clean

2. wash your hands

3. seperate and clean chemicals and equipment

4.   use microfiber cleaning utensils

5. clean and sanitize all work surfaces

hope this !
