I've seen a product advertised on TV but did not write down the name.
Basically, instead of scrubbing the grout lines in your shower-tub, you
simply paint them with this white paint.

The lower tiles (grout lines) above my tub will not clean. I've tried
bleach, oven cleaner, grout cleaner, TSP, naphtha etc. etc.

Has anybody heard of this product? HD & Lowe's don't know anything about
it. I also tried a Sherwin Williams dealer with no luck.

All advice appreciated.
