It depends on how high the PH is and how long it has been out of balance. If PH is high that means the water is more on the scale forming side than the corrosive side of the scale and wouldn't typically irritate the skin.
Not so much the hot tub more like the people in it, the PH levels are for 2 reasons 1 to stop bacteria growing in the hot tub (which is bad for the user not so much the tub) 2 to stop the liquid in the hot tub melting the occupant of the hot tub (melting might be a little strong but serious irritation and sickness can occur if your tub is not properly maintained) Side note: if the PH is way off it could adversely affect parts of the hot tub, but if it's that extreme you will be in for a nasty time if you get in it.
Options for hot tub chemicals include standard bromine or chlorine for disinfectant, pH plus and pH minus to adjust pH levels. Some hot tub owners who want more environmentally friendly solutions that use less chemicals are using ozonators, bromine or chlorine salt generators (salt systems), Waters Choice enzyme treatment which reduces chemicals needed, and mineral sticks.
While it would lower the pH, sulphuric acid is a strongly oxidizing acid too that will burn organic materials (flesh) and is thus not safe for use in pools and hot tubs. Use only hydrochloric acid (sold as muriatic acid in stores) for the purpose of reducing pH in a pool or hot tub.
You can use baking soda to raise the pH level in a hot tub, however soda ash will work better. Borax even better than that. The issue with baking soda is that it more readily raises Total Alkalinity so will have a larger effect on TA rather than pH.
It could be a few things, Alkalinity, high PH, Calcium deposits or skin and oils. Test the water to determine if PH and Alk. are in the correct parameters first. If Calcium is too high it will leave the deposits but most of the time the filter isn't able to remove all of the skin and oils that we lose from the epidermis quickly enough and they stick to the shell.

I do, because I have a Hot Tub, and maintaining a proper Ph is necessary for proper maintenance.
Test chlorine levels to see if they fall between 3-5 mg/l (ppm) and dose according to the attached instructions on the Hot Tub Chorine container.Test Hot tub PH levels to see if they fall between 7.2 and 7.6. If not within these parameters use Hot Tub pH Plus or Minis according to instructions.If water is foaming use Hot Tub Anti Foam
Scoop them out with a net making sure there are no remaining eggs or tadpoles. Drain and clean your hot tub. This will have to be done as the little green frogs probably decafetated in your hot tub and contaminated your water. Refill with water and test that you have a proper pH balance. And then keep your hot tub covered when it is not in use.

Hot water increases the release of histamines, and makes you itchy...or itchier. If you are itchy after you get out of the hot tub, the water chemistry may not be in order. Proper sanitizer levels and pH levels between 7.2-7.6 are required.
The most common chemical for hot tubs is Bromine. You will also find chemicals that adjust the PH, reduce metals and clean the water. For more information on hot tub chemicals, visit lesliespool.com.

what's the ph. for hot cocoa
Hot tubs are an investment and a wonderful luxury. This guide will help you maintain the water balance in your hot tub or spa with minimum care. Chemical levels checked on a regular basis and occasional sanitization of a hot tub may be required. When a hot tub should be checked, how and for what will be covered in this step by step guide. ▪ Step1: Check the hot tub chemical balance weekly. Testing strips or drops can be used on either hot tubs that use bromine or a naturally purified hot tub. Test strips for naturally purified hot tubs will reveal the amount of monopersulfates, alkalinity and pH in the water. For a bromine use hot tub, testing will provide amounts of bromine, chlorine, alkalinity and pH levels in the water. Testing chemical levels in a hot tub or spa is important to avoid problems mineral build-up, scaling and foul-smelling water. ▪ Step 2: Know how to adjust the hot tub chemicals. Ideally the calcium hardness level should be between 100 – 200 mg/l. If the level is below this you could end up having corrosion damage. Alkalinity for a hot tub should be between 125 – 150 mg/l, the pH range should stay between 7.4 -7.6 and chlorine levels should fall between 3-5 mg/l to keep chemicals at an optimum level. If these chemicals are out of range, the effectiveness of chemical additives will be decreased. ▪ Step 3: Give your hot tub a shock treatment. Strength of shock treatment and its use will depend on how much a hot tub is used. Typically for bromine or chlorine use hot tubs, a strong shock treatment once per week will suffice. For naturally purified hot tubs however, you should use a light shock treatment after every use with a follow-up strong shock treatment once per week to maintain a healthy balance. ▪ Step 4: Ensure your pump is working effectively. Hot tub filters circulate water, avoiding a breeding ground for bacteria and algae. Replace your filter every six months to a year months and regularly ensure your filter basket is not clogged by debris. ▪ Step 5: Clean your hot tub. Approximately every three months, you should replace old water with fresh water. The hot tub cover may also be cleaned using a weak chlorine solution and by using a conditioning treatment chances of cracking or weathering of the top will be reduced. A well maintained hot tub or spa will reduce the likelihood of corrosion damage and the chances of algae and bacteria growth. Sustaining effective water balance enables safety and enjoyment for its users.
