Kemiko Neutra Clean FAQ’s 

Question:  How much Neutra Clean do I use?  

 Follow instructions on the bottle : For light cleaning of dirt, dust and light amounts of grease, use 10 parts water to one part Neutra Clean.

For Medium clean up of dirt, oil, grease, light overspray of drywall mud etc., use 5 parts water to one part Neutra Clean.

Heavy Duty clean-up of grease, oil, grime, latex paint overspray , use one or two parts water to one part Neutra Clean.

For step 3 – Neutralizing, use 8 - 10 parts water to one part Neutra Clean to remove the acid residue and colorant left behind after acid staining the floor. 

Question: Why do I need to use the Neutra Clean? 

Neutra Clean was developed with the sole purpose of being used as a cleanser in preparing the floor for acid staining and as a neutralizer in removing the residue after acid staining the floor. This product is an all liquid material and will not leave behind more residue like you will get from using Trisodium Phosphate (TSP) and baking soda. 

Question: Will Neutra Clean harm my plants? 

When cleaning the slab, Neutra Clean one must take precaution in removing the mixture of Neutra Clean and water from the surface of the concrete. Try to keep the residue off of the landscape as much as possible. The product is biodegradable and will most likely not harm the vegetation, but like other detergents, it should not be introduced to the ground or plants. 

Question:  Can I use Neutra Clean as a concrete cleaner? 

Yes. The Neutra Clean is a metasilicate cleaner that is used to remove deleterious matter, such as grease, grime, soil and other construction related material from the floor surface. Typical applications include commercial kitchens, grocery stores, restaurants, showrooms floors, walkways and many other surfaces requiring cleaning. 

Question:  What is the coverage of the Neutra Clean? 

That depends upon the dilution rates but typically the coverage would be between 500 – 2000 square feet per gallon, per application based upon dilution ratios. 

Question:  Do I have to neutralize the floor after applying the acid stain? 

Answer: Yes. By neutralizing the acid stain’s reaction with the Neutra Clean, it is stopping the acid reaction with the floor and locking in the color that has been achieved. This will also remove the powder left behind from the reaction of the acid with the concrete and any additional colorant that did not absorb into the concrete floor. This is the most important step if you plan on sealing your concrete. If you choose not to neutralize or you do not clean the floor entirely, this will have an adverse affect on the sealer’s ability to bond to the concrete.  

Question:  I cleaned and neutralized the floor. How clean does it have to be? 

You will have to clean the floor enough so that when you do the clean water rinse the water stays clear and is free from any colorant in the water. This is an important step in the acid staining process. The floor can never be too clean.

If the surface that has been acid stained is not properly cleaned, it will have an adverse affect with the sealer bonding to the concrete. Any powder that is not removed from the surface will attach itself to your sealer and will not allow the sealer to dry and bond to the surface of the floor. This may cause the sealer to eventually lift or peel off of the floor. Think of putting tape on a dusty table. The tape will stick for a little while but it will eventually fall off because the tape stuck to the dust (residue) and lifted off. The same thing will happen with the residue that is left behind. The sealer that is applied will eventually lift off of the floor. To see if the floor is clean enough for sealing, test the floor by wiping a damp old t-shirt or old towel across the surface of the floor.  Do not scrub, just lightly wipe.  If the rag or t-shirt gets color on it, that is residue and needs to be cleaned again. If the rag or t-shirt is mostly clean and you are confident that all of the residue is removed, you are ready to seal. 

Question:  How much Neutra Clean do I need to add to my water mixture to clean the residue? 

 Kemiko recommends that you have a mix ration of 10:1 water to Neutra Clean when removing the residue from the floor. 

Question:  When I cleaned the residue off of the floor most of my color came with it, what happened? 

The acid stain did not penetrate and react with the lime in the concrete. This could be caused by a number of reasons. If the surface of the concrete has been power troweled and the surface is smooth and slick, the acid stain did not penetrate. Curing compounds used on finished concrete also works as a barrier and does not allow the acid stain to penetrate the surface. These situations can be remedied by dry sanding the surface with 150 grit sand paper. This opens the pores of the concrete and allows the acid stain to reach the lime in the concrete. Fly ash will also prevent the acid stain from getting a chemical reaction with the lime in the concrete. Fly ash is an additive that is added to concrete to help with the curing of the cement. fly ash, as well as other additives, will work adversely with the acid staining process and when they are used, acid staining most likely will not be an option.

Fly ash is added to the concrete and replaces cement in proportion. If the concrete has 25% fly ash it means they removed 25% of the cement in replacement. Concrete has lime and lime is what is needed to achieve a chemical reaction with the acid stain.
