CLR Calcium Lime & Rust Remover - 28 fl oz

A: Dishwasher: REMOVE dishwashing rinse agent before using CLR Calcium, Lime and Rust Remover. Pour a 1/2 cup of CLR Calcium, Lime and Rust Remover directly into the bottom of an empty dishwasher (no glasses, dishes, or flatware but the racks can stay). Run a normal cycle followed by an extra rinse cycle. Make sure there are no detergents or any other chemicals in the machine while using our product. Washing Machine: Run your empty machine (no clothes) without detergent up to the main wash cycle, which is where the water stops and the cycle is about to agitate. Stop the machine and add one-half cup of CLR Calcium, Lime and Rust Remover directly into the tub of the machine. Finish cycle. Run one additional full cycle (wash and rinse) with water only to rinse machine fully. If your machine is HE (high efficiency) and/or 'Water Saver' we recommend using a 1/4 cup of CLR Calcium, Lime and Rust Remover, instead of the normal 1/2 cup recommended for any other type of washer/dishwasher. For Front Loading Machines: Simply add a 1/2 cup of CLR Calcium, Lime and Rust Remover to the soap dispenser (only 1/4 of a cup for HE machines). After the full cycle has completed, run an additional rinse cycle with just water. Make sure there are no clothes or other chemicals in the machine when using our product.

A: Add a ½ cup of CLR to either machine where you normally would add your detergent or softener and run your machine. With both types of washers, once the cycle with the CLR has finished, run an additional full cycle with just water. If your machine is high efficiency or “water saver” only use ¼ cup of CLR.

The more water in the toilet bowl, the more diluted the product becomes rendering it less effective.

A: We do not recommend using our CLR Calcium, Lime and Rust Remover on porous materials such as rubber.

A: Our CLR Calcium, Lime and Rust Remover is safe to use on faucets made of chrome or stainless steel only, so if your faucet is made of either one of those metals, it would be safe.
