Renew Labs Water: Frequently Asked Questions

Renew Labs deionized water is water that has had its dissolved minerals, such as calcium, magnesium and iron, removed by deionization. It is made and bottled in Houston, Texas by Renew Lab Group and packed for specific household, automotive, garden and hobby uses. Shop all lines in Renew Labs Deionized Water.

Renew Labs water is manufactured by Renew Lab Group in Houston, Texas, USA. Every line is filled and labeled for one job, with use-specific directions on the bottle and a resealable cap. Browse the full range in Renew Labs Deionized Water.

Tap-water minerals are what cause white spots on glass and paint, scale in steam irons, white dust from humidifiers and buildup on battery plates. Deionized water has those minerals removed, so it adds water and nothing else. The USGS explains how calcium and magnesium make water hard (USGS).

No. Renew Labs water is sold for household, automotive, garden and hobby uses only and is not for consumption. Keep it out of reach of children and pets, and keep it in its labeled bottle so it is never mistaken for a beverage.

Unscented Renew Labs lines are deionized water with nothing added. The Linen & Ironing Water is available lightly scented in Lavender and Fresh Linen, and also Unscented. Scented linen water is for misting onto fabric, not for an iron’s tank. See Home & Linen Water and our linen water guide.

Renew Labs products are sold on this website and through selected wellness centers and online retailers. Buying here gives you every size and pack, including 2-packs and 4 gallon cases, with shipping calculated by weight at checkout and shipped from Houston, Texas.

No, but they are close for most household jobs. Distilled water is boiled and the steam is condensed, leaving minerals behind. Deionized water passes through ion-exchange resin that swaps dissolved mineral ions for hydrogen and hydroxide, which recombine into water. Both are low in minerals. Our deionized water guide compares deionized, distilled and reverse osmosis water.

Water flows through beds of ion-exchange resin. Cation resin captures positively charged minerals such as calcium, magnesium and sodium, and anion resin captures negatively charged ions such as chloride and sulfate. The released hydrogen and hydroxide ions combine into water (Xylem). Read the full process in our deionized water guide.

Reverse osmosis pushes water through a membrane that blocks most dissolved solids, while deionization removes ions with resin. RO leaves a small share of minerals behind, so many systems finish RO water with a deionization stage for a spot-free result. Our deionized water guide has a side-by-side table of deionized, distilled, RO and tap water.

Very poorly. Water conducts electricity because of the dissolved ions in it, so removing those ions lowers conductivity sharply (USGS). That is why conductivity or TDS meters are used to check deionized water. It still is not safe around live electrical parts, so always unplug appliances before filling them. Learn more in the deionized water guide.

Deionized water does not spoil like food, but once opened it slowly absorbs carbon dioxide from the air and can pick up traces from its surroundings. Keep the cap tightly closed, store it at room temperature out of sunlight, and use opened bottles within a reasonable time for best results. See storage tips in our guide.

Keep the cap tightly closed and store the bottle at room temperature, out of direct sunlight and out of reach of children. Don’t refill the bottle with tap water, which would add minerals back. More storage tips are in our deionized water guide.

Choose by use: Battery Water for flooded lead-acid batteries, Radiator & Coolant Mixing Water for antifreeze, Steam Iron & Garment Steamer Water for irons and steamers, Humidifier Water for humidifiers, Car Wash Spot-Free Rinse Water for vehicles, Window & Glass Spot-Free Water for glass, Linen & Ironing Water for fabric, Plant & Orchid Water, Aquarium Top-Off Water, Soap Making & DIY Cosmetics Water, and small bottles for aromatherapy, cosmetics, jewelry and lenses.

Yes. Battery makers such as Trojan recommend distilled or deionized water for flooded lead-acid batteries, never tap water, and topping off after charging (Trojan Battery). This applies to cars, golf carts, boats and solar banks with removable caps. Read the car battery water guide or shop Automotive & Battery Water.

Yes. Mixing antifreeze concentrate with mineral-free water helps avoid scale from hard tap water. Follow the coolant maker’s mix ratio, usually 50/50, and never open a hot radiator cap. Renew Labs Radiator & Coolant Mixing Water is made for this; see Automotive & Battery Water and our battery and coolant water guide.

Yes. Renew Labs Humidifier Water and Steam Iron & Garment Steamer Water are made for those appliances. Always follow your appliance maker’s directions. Some iron makers, such as Rowenta, advise mixing demineralized water 50/50 with tap water, so check your manual. Shop Steam Iron & Humidifier Water.

White dust is the minerals in tap water. Ultrasonic and impeller humidifiers throw tiny droplets into the air, and when they dry, the minerals are left on furniture and screens. The EPA suggests using water with lower mineral content to reduce it (EPA). See our humidifier water guide or Renew Labs Humidifier Water.

Usually, yes, but check your manual first. Philips designs its irons for tap water but recommends demineralized water, or a 50/50 mix with tap, in hard-water areas, and Rowenta also suggests a 50/50 mix (Philips, Rowenta). Low-mineral water reduces scale and brown spitting. Read what water to use in a steam iron or shop steam iron water.

Not scented linen water. Philips advises against putting fragrance or other additives in an iron’s water tank (Philips). Mist scented linen water onto fabric before ironing instead, and use unscented water in the tank. Our linen water guide explains how, and Home & Linen Water has Lavender, Fresh Linen and Unscented.

Wash and rinse as usual, then finish with a final mist of deionized water from a clean pump sprayer before the car dries. With no minerals in that last rinse, nothing is left behind to spot. Work in the shade on cool panels. Our spot-free rinse guide walks through it; shop Car Wash & Glass Spot-Free Rinse.

Yes for mineral-sensitive plants. The International Carnivorous Plant Society recommends low-mineral water for Venus flytraps (ICPS), and orchid growers watch salt buildup in pots (AOS). Orchids still need a balanced fertilizer. See deionized water for plants and orchids or shop Plant & Aquarium Water.

Use it to top off evaporation. When aquarium water evaporates, the minerals stay behind, so topping off with tap water slowly raises hardness. Topping off with deionized water replaces only what evaporated. For water changes, remineralize to suit your fish or reef. See our plant and aquarium guide and Aquarium Top-Off Water.

Mineral-free water. Minerals in tap water can react with lye and oils, which may cause soap scum, dullness or spots, and can shorten the shelf life of lotions. Makers use deionized water for consistent batches. Always add lye to water, never water to lye. Read our soap making water guide or shop Soap Making & DIY Water.

Yes. Deionized water dries without mineral spots, so it is a gentle final rinse for eyeglasses, camera lenses, screens, gold, silver and watches. Follow the maker’s care directions for coated lenses, pearls and porous gems. Shop Lens & Screen Care and Jewelry Care, or Aromatherapy & Beauty Formulation for blending.
