As a cleaning professional, kitchen window cleaning is my specialty. Kitchen windows tend to accumulate grease stains. I start by soaking a cloth in warm water to wipe away dust initially, then evenly spray a strong degreaser on the glass and window frame, letting it sit for a while to allow the grease to dissolve thoroughly. Next, I scrub meticulously with a scouring pad, paying special attention to crevices. Finally, I use a squeegee to remove all residue and wipe the edges dry with a clean soft cloth. After this process, the windows instantly become crystal clear, creating a fresh kitchen environment for you.
