PurActive Scrubbing Sponges feature a special coating that easily lifts stubborn grease and grime while remaining gentle on all hard surfaces. They clean three times more effectively than traditional, nonscratching scourers. Foam backing is soft and fits comfortably in your hand for enhanced ergonomics and a good grip. Hardworking sponges clean a variety of surfaces where a scratch-free finish is required. Test them on an inconspicuous area first.
