I usually keep my tools where I can find them so not buying multiples.
BUT, dang I use a lot of paper towels and Qtips (cotton buds) !
Rog
Rog, I'm so cheap that I re-use my paper towels that I mop water up with. I hang them up in the basement and re-use them at my next steam-up. Oily ones are disposed of and I try not to re-use Q-tips, especially in my ears

By the way, the best paper towel I have found is made by the brand Viva. They are cheap, durable and absorbent.
