This oven cleaning kit has everything you need to efficiently clean ovens with AquaLift™ self-clean technology. Contains (1) expanding sponge, (1) scrubbing sponge, and (1) scraper. Use the scraper to easily remove soil that has burned on extensively after running AquaLife cycle. The sponge is double-sided. One side is smooth to wipe away spills loosened by the AquaLift cycle, and the other side is rough for more stubborn stains. The expanding sponge soaks up the residual water left in the bottom of the oven cavity.
