Do you hate how grungy looking your clear blocks get?
You can clean them with Dawn dish soap. It cuts the oil from your hands.
You can use the Mr. Clean sponges on more stubborn ink stains.
I’ve even used the Stazon ink remover to get the White Stazon off the blocks.
It doesn’t hurt the blocks.
If you get adhesive on the blocks, you can use the eraser from in the catalog to get the adhesive off.
They'll look good as new!
