With CLR's array of cleaning solutions, understanding application and ingredients is key. Below are FAQs addressing common concerns and usage instructions for our products. Ensure optimal results by familiarizing yourself with these guidelines.
Will Calcium, Lime and Rust Remover remove oil from my concrete driveway or garage floor?
We do not recommend using our Calcium, Lime and Rust Remover to remove oil. If Calcium, Lime and Rust Remover is mixed with oil, it will darken the concrete, which is very difficult to remove.
How do I clean hard water deposits from my drinking glasses?
To clean hard water stains, we recommend using a 50/50 solution (equal parts of Calcium, Lime and Rust Remover and warm water) into a glass or porcelain bowl. Apply solution to the affected stained areas of the glasses using a damp cloth or sponge. After 2 minutes, rinse thoroughly with cold, clean water. If it seems that Calcium, Lime and Rust Remover helped a bit but the glasses are not completely clear, repeat at full strength if necessary. Due to the natural density and hardness of calcium as a mineral, the calcium can actually etch and embed itself into the material of the glass (usually present by having a cloudy appearance vs. spotty).
