MAGIC ERASERS!
These are actually just melamine foam which can be purchased on ebay for a lot less than the store bought stuff.
When To Use Magic Erasers I'm a big fan of Magic Erasers because they do things that other cleaners don't.
They let you trap and remove oil based stains and marks without having to use a de-greaser. That's a huge advantage because it means no caustic chemicals to breath or pollute. Love that!
Perhaps the people who appreciate these sponges most are moms of children who get get inspired with crayons and markers. But here are some other uses home stagers can appreciate.
Remove rust stains from PVC pipes under sinks, behind toilets, and on the floor of the vanity.
Get the interior of your dishwasher white again.
Clean the oven to look like new.
Clean stains from your smooth top stove.
Get scuff marks and stains off vinyl flooring.
Remove the water mark from the sides of your pool.
Make glass shower doors sparkle.
Pull stains out of carpets and rugs.
Refresh older laminate countertops like nobody's business.
When Not To Use These Sponges. The eraser sponge can burnish flat paint or dull shiny paint if you scrub hard. But if you have to use it on painted walls, it will be easier than painting the entire wall when you aren't able to do paint touch-ups. You can minimize sheen differences if you proceed with caution, using the least pressure necessary.
Do not use on wood paneling or varnished wood surfaces. Do not use on skin or animals. Do not use on delicate fabrics. Test leather in an inconspicuous spot before using.
I've found that rinsing is crucial to the success of Magic Erasers. They will leave a visible white residue on some surfaces, like shower doors.
I've also discovered that the generic knockoffs available at dollar stores and discount big box stores are just as good as the name brand.
