Safest Rust Remover or Evapo-rust or ??

I have a small container with the solution that I keep using. It's just getting browner. I'll have to look for the pH test kit and check it. </div></div>


If you are doing a big job you will need to add water due to evaporation of the material. Big jobs require a shower bath with constant flow. For small jobs (up to drive shaft dipping) straight product is usually fine (if you cover it) since you can usually control the evaporation rate that way.

Now here is the difference between Evapo rust and Safest rust remover:

The evaporation rate on Evapo-rust is chemically unacceptable with a shower bath that is why they recommend not to use it in a shower. look at the FAQ's for Evapo rust Here: http://www.evapo-rust.com/product-info/

The evaporation rate with Safest rust remover is more controllable and is acceptable with a shower bath.

In my experience with both products a shower bath always beats immersion in time of use and effectiveness especially on pitted surfaces.

Now that we are on the same page with the differences with both products on to the question:

Why will PH screw up the product? <span style="font-weight: bold"> Never add tap water until you have verified the PH -- WHY?</span>

Neither company will not tell you not to use tap water because they want you to buy more product. <span style="text-decoration: underline">Always maintain a PH neutral chemical for Maximum product life.</span>

I always use distilled water for any addition as make up for evaporation. http://www.okpure.com/article_005en.html
