### ⭐⭐⭐⭐⭐ easy to use, let the stuff do the work, spray it on in the shade and let it sit.
*by S***R on June 23, 2025*

Literally made my 2006 all white boat interior look new! Almost no scrubbing needed. sprayed it till it was wet, let it sit for 5 minutes, and I have ZERO spots left of black. pure white again!! My seats were covered with black and I was about to have them re-covered (I have a few holes in the seats so I'm headed towards that anyway but this still might delay that by a few years. even my wife commented that the boat seats look new and asked it I had spent some money that we had not talked about 😂
