Sherwin Williams recommended their environmentally friendly cleaning product. That and a good scrub brush worked very well. I was pleased.

We bought a product at Home Depot called Spray & Forget. You just do as it says. No scrubbing. You can Google it and read about it.

Lowe's sells a product with a somewhat similar name. But after reading about each on-line, I decided the Spray & Forget was the safest to use.
