Cleaning Up with Sakrete Dissolver

You can clean plastic molds with soapy water or denatured alcohol, but you have to be careful about scrubbing the plastic with something that's abrasive (like a heavy duty sponge) because it will scratch and dull the plastic. The scratches and dullness will show up in the next piece you cast. Using a Concrete Dissolver and following the steps below will help keep your plastic molds shiny and clean.

Materials and Supplies:

• Concrete Dissolver like Sakrete Concrete Mortar Dissolver
• Soft Sponge / Cloth / Paper Towels
• Rubber Gloves (recommended)
• Dirty Tools or Molds

Step 1: Spray the piece with Concrete Dissolver:

Step 2: Leave the dissolver to soak for 5-15 minutes.

Step 3: Wipe off the residue with a paper towel. You might use a soft brush or sponge to get into the textured parts of the mold.

Step 4: If the piece is still dirty, spray it with more dissolver and repeat the steps above. Otherwise rinse the piece off with water and let it dry.

Step 5: The mold is clean and ready to use again.

It used to take 5-10 minutes to scrub and clean a mold before using it again, but with Sakrete Dissolver it only takes a few seconds to spray it on, wait a bit, wipe it off, and rinse with water. It's well worth the $14 for a bottle, and you can pick it up at most Home Depot locations that have ShapeCrete on the shelves.
