How to Clean Cured Cement From a Trowel

After working with cement, pouring a patio or sidewalk perhaps, you will have plenty to clean up before the cement hardens and cures. After cement cures on surfaces, you may think you are stuck with it. Not so, thanks to a product known as molecular cement dissolver. Instead of using harsh or dangerous chemicals, use a harmless solution made with sugar cane syrup to clean cured cement from a trowel.

Place the trowel into a bucket with the cured cement facing up.

Spray Back-Set molecular cement dissolver thoroughly over the cured cement on the trowel, covering the cement generously.

Wait about 20 minutes for the cement dissolver to work on the cement. Spray the trowel a second time and wait 10 minutes more while the cement dissolver works on the trowel.

Spray the garden hose onto the trowel to remove the cement. After the cement dissolver reduces the cement to a mud-like consistency, spraying the trowel with a hose should effectively remove the cement.


The molecular cement dissolver is a non-hazardous solution. The product is biodegradable and does not contain dangerous fumes. You can safely use the cement dissolver on aluminium, stainless steel, brass, chrome, glass, plastic and rubber. If the cured cement does not easily wash away from the trowel with the garden hose, brush it off with a stiff brush and then spray the trowel with the hose.


Keep the molecular cement dissolver away from other cement surfaces because it will have a corrosive effect on cement and concrete.
