Surface Disinfectant FAQ: 15 Questions Distributors and Cleaners Ask

Surface and floor disinfectants protect hospitals, food plants, offices, hotels and homes. Below are direct answers to the 15 questions distributors, facility managers and cleaners most often ask.

What's the difference between cleaner, sanitiser and disinfectant?

Cleaners remove dirt. Sanitisers reduce microbial count to a "safe" level. Disinfectants kill pathogens on inanimate surfaces. Most workflows need both clean and disinfect — clean first, then disinfect.

What are the main families of surface disinfectant actives?

Quaternary ammonium (BAC, BKC), phenolics, sodium hypochlorite (bleach), hydrogen peroxide-based, alcohol (IPA / ethanol) 70%, peracetic acid, chlorine dioxide. Quat and phenolic dominate routine institutional use.

What contact time does a surface disinfectant need?

Varies by chemistry: quat and phenolic 5–10 minutes; bleach 1–5 minutes; alcohol 30 seconds–1 minute; accelerated hydrogen peroxide 1–5 minutes. Read the label; observe the time.

Why is "spray and wipe" not really disinfection?

Because most chemistries need contact time to kill organisms. Spraying and immediately wiping removes visible soil but leaves microbes alive. The surface looks clean but is not disinfected.

Concentrate vs ready-to-use (RTU) — which is right?

Concentrate is cheaper per litre of working solution; facility customers buy it. RTU is foolproof for small offices and consumers but more expensive per use.

Can I mix two surface disinfectants?

No. Bleach + quat inactivates the bleach. Bleach + acid releases chlorine gas. Phenolic + bleach forms irritants. Use one chemistry; rinse between if switching.

What's the right dilution for a quaternary ammonium concentrate?

Read the label. Typical use-dilutions are 1:64 to 1:256 from concentrate. Under-dilution wastes product and may damage surfaces; over-dilution does not disinfect.

Is bleach a good general-purpose disinfectant?

For occasional heavy disinfection — bathroom deep cleans, blood spills, sickrooms — yes. For daily wiping it is hard on surfaces and air quality; a quat or peroxide product is gentler.

Which disinfectant is safest for hospitals?

There is no single answer — most hospitals stock a quat or accelerated peroxide for general surfaces, plus hypochlorite for spore-risk areas (C. difficile), plus 70% alcohol wipes for medical-device exteriors. Infection-prevention protocol drives the choice.

Are surface disinfectants safe for pets?

Most are not safe for pets to lick, walk on while wet, or be exposed to during application. Let surfaces dry fully and ventilate before pet access. Phenolics are particularly toxic to cats — use quat or peroxide-based products in pet households.

What surfaces can I NOT use bleach on?

Stainless steel (prolonged contact corrodes), aluminium, marble, granite and other porous stone, leather, silks, wool, and many painted surfaces.

What efficacy testing should a hospital-grade disinfectant have?

EN 1276 (bacteria), EN 14476 (viruses) for European-style reference; AOAC use-dilution test; or an equivalent Indian pharmacopoeial efficacy test. Ask the supplier for the test report.

What pack sizes do facility customers buy?

5 L concentrate jerry cans for institutional use; 1 L RTU for office facility cleaning; 500 ml RTU for retail / household.

What is a hospital-grade RTU disinfectant?

A ready-to-use formulation with documented hospital-environment efficacy at the stated contact time — typically quat, accelerated hydrogen peroxide, or chlorine-based.

How much should I expect to pay wholesale?

Mid-2026 Indian wholesale: quat concentrate 5 L ₹500–900; phenolic concentrate 5 L ₹450–800; bleach 5 L ₹250–400; RTU spray 500 ml ₹70–130 [VERIFY against current quote].
