Grout cleaners and advanced puck lights

[bradleyheathhays]

It's been so long since I've tried to clean my bathroom grout that I'm hoping there's been an improvement in grout cleaners since I did, so I thought I'd ask yall's opinion on how best to get my grout color back. It's white but fairly darkened now with just general floor dirt over the years. It was sealed a long time ago but not sure how much good it did.

Is there some kind of product now that is a combination cleaner / re-colorant? I'm guessing there might be.

Also, I need kind of an advanced puck light that I'm not finding on Amazon. I need one that's programmable and remote control. Any suggestion where I can find something like this?

Thanks

PS. I've got 1" tile on the floor, which means a LOT of grout lines, which means one of those grout re-colorant pens would just be too much work

I would start here and widen my search from there.
As far as the puck light , if you can't seem to find the puck, have you considered a single section of led tape with those characteristics?
Also look through the 12 volt lights at the parts store.
There are all kinds of little odds and trinkets in the lighting department for the interior of cars.
