Yes, you must mix CLR with water for most cleaning tasks to prevent damaging the surfaces. The standard mixing ratio is 50% CLR and 50% water.
For light stains and buildup, a diluted mixture of 1 part CLR to 8 parts warm water is recommended. For moderate stains, you can use a 50/50 solution of CLR to warm water. For stubborn build up, full strength is recommended, but only when diluted has been tried first. Always rinse with cold water to neutralize.
Leaving CLR (Calcium, Lime & Rust Remover) on a surface for too long causes the acidic formula to eat through the finish, resulting in surface etching, discoloration, pitting, and corrosion. It can also leave behind a sticky, difficult-to-remove film as it dries out.
Do not use standard CLR (Calcium, Lime & Rust Remover) on soft metals (brass, copper, aluminum), natural stone (marble, granite), colored grout, wood, wallpaper, carpeting, or any painted, coated, or sealed surfaces. The acidic formula can cause pitting, discoloration, or permanently strip finishes.
Let it dwell for no longer than 2 minutes, then rinse thoroughly with cold water. Repeat if required. Avoid mixing with bleach or other household cleaning products, and consult the manufacturer's guidelines before use.
Whether CLR or vinegar is better depends entirely on the stain and the material you are cleaning.

Hotels keep glass shower doors spotless by combining strong commercial cleaning agents with routine maintenance and smart preventative coatings. Because they deal with heavy daily guest turnover, housekeeping staff rely on quick but highly effective strategies to prevent soap scum and hard water buildup.
You should never leave CLR in a toilet bowl overnight. Because it is a highly acidic formula, extended exposure can wear down the porcelain's protective finish, damage internal plumbing parts, and degrade rubber or silicone seals.
Plumbers recommend cleaning toilets using distilled white vinegar for safe, natural maintenance, or commercial acidic/enzymatic cleaners for tough mineral buildup. They strictly advise avoiding harsh chemicals like drop-in bleach tablets, which can corrode internal rubber flappers and flush valves over time.
CLR should not be used on wood, clothing, wallpaper, carpeting, natural stones, brass, copper, aluminum, galvanized metals, and any painted, coated, or sealed surfaces. CLR stands for calcium, lime, and rust and — as you may imagine — it is designed to clean these things specifically.
