CLR is a well-known product that effectively removes stubborn lime, calcium, and rust stains. Its powerful formula is also eco-friendly, containing a high amount of biobased ingredients. This has earned it certification from the USDA's Bio Preferred program.
This was my first time using it, and it worked great! I had plenty of work time, and just 24 hours later it was fully cured and ready to go. Excellent product with fast service. Pilots HQ is now my go-to source for epoxy—it’s the best because it’s strong and reliable.
