If it seems that the Calcium, Lime and Rust Remover did not help at all, the glasses may be etched and there is no remedy to remove the cloudiness from the glasses. The cloudiness is actually tiny cuts made in the glass by deposits in the water. The only thing that may remove the etching is a jeweler’s polish.

Pour enough CLR PRO Calcium, Lime & Rust Remover to cover bottom. Add one cup of warm water, allow mixture to soak and thoroughly rinse with clean water. Using a soft scouring pad while our product is sitting on the stains is recommended. Always check with the manufacturer of your coffee pots first for their recommendations of products that are safe and effective on their materials.

Dishwasher: REMOVE dishwashing rinse agent before using CLR. Pour a 1/2 -1 cup of CLR, depending on the capacity of washer, 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 1/2 - 1 cup of CLR, depending on the capacity of washing machine, 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, 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 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.

Use only on metal filters. Dilute equal parts of Calcium, Lime and Rust Remover and warm water into a plastic container. Dip the filter into the solution for about two minutes. Brush to loosen buildup and rinse with cold, clean water. Allow to dry.

We do not recommend using CLR PRO Calcium, Lime & Rust Remover on any natural stones, especially marble (even synthetic). The acids in our product will remove the seal, penetrating the marble and can compromise the natural beauty of marble.

We do not recommend using CLR PRO Calcium, Lime & Rust Remover on galvanized metals. When a metal is galvanized, a Zinc coating is put over the metal (usually to protect it from rusting). The acids in CLR will remove the Zinc which could compromise the material.

We recommend using or disposing of CLR within 3 years. Make sure cap is securely fastened after each use.
