Frequently Asked Questions

The following are frequently asked questions submitted to our Technical Service staff. We urge you to contact a TQH Advisor whenever there is a need to do so. We are committed to serving in your best interest.

Can I effectively kill germs and remove soil at the same time?


Using a disinfectant-detergent solution would allow you to do a little of both, but not both completely. Germs live in soil and act as nature’s recyclers. They cannot leave the soil and live life on their own. If you remove the soil, you are removing the germs. Disinfectant solutions are designed to be applied to a clean surface and last for a few hours to kill airborne germs that land on the previously clean surface. The best you will achieve is to kill some of the germs and the dead germs will be replaced by stronger and possibly more dangerous germs already residing in the left-behind soil. Therefore, if the soil is not completely removed, and disinfectants are continually applied, a sort of super germ farm can emanate.

The most effective approach for maintaining healthy surfaces is to wash well with a TQH-Certified detergent and rinse thoroughly when necessary. When washing or mopping with a TQH-Certified detergent mixed in cold water, a rinse step may be eliminated if the soil-containing solution is removed thoroughly from the surface being washed with a well wrung out mop or a clean dry cloth. When you cannot see to the bottom of the washing solution container, it is time to throw out the “dirty water” and mix up a batch of fresh detergent solution.

How do I stop resident walkers and dining chairs from scuffing and marking my waxed floors? Chair glides only work for a short time?


If every chair and walker seems to be scuffing and marking, you do not have a chair or walker problem. You have a detergent problem! If a detergent cannot clean 100% using cold water, soil is being left behind. Left-behind soil contains grit and sticky binders which get rubbed into the floor. The rubbed-in soil leaves a mark on the floor as well as builds up on the bottom of the chair or walker glide. As time passes, the buildups and scuffs worsen. Once you switch to a TQH-Certified cold water detergent, the scuff marking will diminish dramatically or even stop totally.

How do you get a detergent’s fragrance to last for a long time?


Generally, fragrance sprays and additives are used to counteract and mask offensive odors. That is the wrong logic to apply to an odor problem. Odor is a symptom of decaying soil. If you remove the cause, the result is the elimination of the symptom. The lack of odor is acceptable to most everyone. Therefore, wash with a cold water detergent solution that will remove all of the soil and with the soil will go the odor.

If a detergent is not neutral, is it safe to use?


The safety and quality of a general detergent revolves around the quality and/or purity of the raw materials. The most important properties of a detergent are: 1.) It must work in the coldest water; 2.) It must lift 100% of the soil and dry residue-free; and 3.) A mixed solution must not damage surfaces, fixtures, tools, etc. Even though safety apparel should be used, a quality general detergent should not be dangerous if skin contact is made.

Why can a floor finish become less safe as time passes?


When a floor finish seems to be “slippery”, it is due to foreign materials building on the floor surface. Soil is made up of grit, dust, and binders — grease, oil, & animal fat. When a poor detergent is used in an effort to wash away soil, it leaves a soil-containing residue. The binder in the soil film acts as a lubricant and footwear traction-reducer. Introduce water into the equation and you have an accident waiting to happen.

Most often, a slippery floor is a symptom to a detergent problem and not a floor finish problem. The quality of a wet mop and wringer is important, but a poor detergent will prevent you from getting excellent results in a reasonable amount of time.

Why is washing greasy concrete with acid NOT correct?


Acid cannot cut through grease, oil, and fat binders. Acid is not a detergent. Acid is used for etching CLEAN concrete prior to applying a paint primer. If you have grease-saturated concrete, use a TQH-Certified detergent solution to soak the surface prior to scrubbing with a silicon-impregnated concrete scrubbing or stripping brush. Scrub thoroughly and rinse well. Many times, the soil may get removed but the concrete may dry darker in spots where the binder may have set longest. As long as the surface is clean and will accept an acid etch, paint primers and coatings should attach well.
