I didn’t think this was going to be such a big deal so I didn’t take a before photo.

A large paint brush I used to put the cement on to the Snail Shell of the Mini Golf..   it hardened full of cement.

So I tried my best.. then gave up.. threw it in a plastic container with 2 month old Activate EM-1 – 100%.. not diluted.

Two weeks later it’s beautiful and ready to go. I tried to clean it every several days. Scrubbing it and helping it along.

It is almost down to the white bristles.  They were dark grey before — it was a used brush when I started with it.

You can see the top of the brush was not in the solution.

I would have thrown it out. I could have used a harsh non-environmental solvent. Then again as I cleaned it the cement product I used is down the toilet and going to the New Town Creek Treatment facility (I went o the tour — read more) — then to the river and a farm in NH which takes NYC’s waste water product. I hope they don’t grow food. but it is processed with  beneficial bacteria in the “digester eggs”– at the New Town Treament Facility in the Digester Eggs.  I asked what kind of bacteria or microbes were used in the digester eggs but he didn’t know the names off the top of his head. I still have not looked that up. I will someday!  Great tour btw of the New Town Creek Waste Water Treatment Facility. The host is very enthusiastic and animated.  Here is the PDF
