Hello, before using your Pella cloth for the first time, please put your PELLA cleaning cloth in the washing machine at a maximum of 40 degrees to remove textile waste. ° Wash without using softener or add warm water and a bit of dish soap into a container and let it sit for 10 minutes. Take your Pella microfiber cleaning cloth, wash it with clear water, leave it slightly damp and start cleaning on the surface you want. If you say you can't clean without medication; You can clean with any detergent you want, except chlorine and chlorine-containing products. Use your cloth by folding it for more efficient cleaning. Do not iron your cloth. All three glands perform the same function. The colors are for separating cleaning areas in the place you will clean. One of the biggest features of the cloths is for general cleaning, on all surfaces (glass, mirror, kitchen, shiny surface, TV, counter, inox, bathroom, faucet, sink, car etc.) you get spotless cleaning without the need to dry with just water. Wipe it off and move on! It does not scratch, leave marks, stains, or dust, and never requires drying.
