The title is not a joke. At my company, we receive keyboard returns from employees who have been fired or fired. I inspect and clean returned items for reuse. Keyboards are by far the most abused. Today I used these brushes for the first time on some particularly nasty keyboards. First I loosen the dirt with a yellow-orange brush. The yellow brushes are great for house dust, while the orange brush works with dried materials. I then blow off the residue with an electric fan and finish with a Clorox cloth and a microfiber cloth. The brushes allow me to work more thoroughly and most keyboards look brand new. By the way, orange brushes are great for removing dirt from the crevices of mice. I'll come back to the strength factor later.
