Dilution of 37% HCL to 4% was created by adrianatitus
I have a 30ml bottle of 37% HCL and would like to dilute it to 4% but only want to make a 30ml bottle of the diluted 4% HCL. Can someone help me with that

Fourth calculator from the top, set to Percentage.
In this example you would combine 875 ml of water with 125 ml of 32% HCL to get one liter of 4% HCL. Be sure to add the acid to the water and not the reverse. The solution will become warm.

The calculator link you provide is offline. Here's another that works well.

Thought I'd put this warning here, regarding the concentration of HCl 37%
When creating Hydrochloric Acid Solution 4% (from hydrochloric acid 37% and distilled water) use caution.
Concentrated HCl is a very strong acid that will burn skin instantly upon contact!
Wear gloves, goggles, and lab coat.
The acid MUST BE ADDED TO THE water (not the reverse)! Otherwise, the drops of water mixing with the concentrated acid will heat up, evaporate, and potentially spew acid from the container.

I am able to buy Black Swan brand where I live. It says: 20%-Muriatic Acid, 28%-Hydrochloric Acid, Am I correct that I should put the HCL percentage (28%) in the calculator? I was confused because I thought Muriatic Acid was the same thing as HCL, so I was surprised to see two different percentages.

That 20% is actually 20 degrees Baume, and that converts to about 28% HCL.
The following is from Brave Search:
"Black Swan brand muriatic acid is a 28% hydrochloric acid solution available in different concentrations, including 20° Baume and 18° Baume variants. It is used for etching concrete floors and walls prior to painting, cleaning brick and cement, removing rust stains from toilet fixtures and metal, and adjusting the pH of swimming pools. The product contains no inhibitors, meaning it will attack metal after rust is removed, and users are advised to neutralize its action with a solution of water and heavy-duty detergent followed by thorough rinsing.
Safety precautions are critical, including wearing protective clothing, rubber gloves, and plastic safety glasses, as the acid can cause severe skin burns, eye damage, and respiratory irritation.
AI-generated answer. Please verify critical facts."

If you decide to use this acid, dilute it outside with the wind blowing the HCL fumes away from you. HCL this strong is dangerous to work with. I no longer use HCL, even 4% HCL.
ALWAYS add acid to water and NOT the other way around.
"Always add acid to water to prevent a dangerous reaction. Adding water to concentrated acid can cause a violent exothermic reaction, releasing a large amount of heat rapidly. This heat can cause the water to boil instantly, leading to splattering or even explosive boiling of the concentrated acid, which poses a significant risk of burns and chemical exposure."

Thank you. If you don't use HCL as the activator, what do you use instead?

Instead of using MMS1, I use Quick CDS made with 50% citric acid. Takes 3 hours to make QCDS.
If I need to use MMS1, I simulate MMS1 by using CDS and SCS as per Protocol-102A (AKA CDM which is CDS + MMS unactivated drops).
See attached PDF file.
