CALCIUM & HARD WATER STAIN REMOVAL:
Hard water stains will appear on the heater and stainless steel skirt. Use the following
products to remove stains and lime build up:
1) ZEP Calcium Lime Rust Remover - commercial grade lime remover is a concentrate
and is also the cheapest (by weight). Home Depot and Lowes carry this product.
Please be aware this product is very strong and gloves are recommended when
handling this material.
2) Lime-Away - this is a home grade lime remover, while not as strong as ZEP, it is car-
ried by most grocery stores.
3) Vinegar - while vinegar works to remove lime stains, this option is by far the most
expensive and can also smell bad when used in larger amounts.
