Hi guys
How do I wash my shop towels that have grease oil and stain in them?
I used to work at a garage that uses a service from a linen company. They wash our uniforms and shop towels. When they come back, its really clean with no stains in them. I have a bunch of towels that I use but don't really want to throw them away. What kind of chemicals do they use? I have bought some sodium triphosphate and kirkland detergent, it works but can't really get the stains off. Thank you
