Improving IPA solution for LSP prep

[Calendyr]

Oh and yes I use 70% concentration instead of 91% because the 70% product sells for half the price of the 91% one around here.

Ok I decided to mix a batch and I will try to use it tomorrow. If it doesn't work well I will go back to the drawing board LOL

So I used:

64 ounces of distilled water
32 ounces of IPA (70% concentration)
1 ounce of baby shampoo
1 ounce of dawn dish soap
1 ounce of liquid hand soap

Could not decide what was best so I used all 3 LOL

So that comes to a little over 3% soap, 23% alcohol. A little weaker than Eraser but still much much stronger than what I used for an IPA solution (10% was my default).

Total cost for 98 ounces: 10$
So that's only 10 cents an ounce compared to 1.24$ for eraser (prices are in Canadian money and includes taxes). HUGE DIFFERENCE!

You actually used 3 ounces of soap in 96 ounces of fluid????

The difference in cost is valid enough but will its performance equal CarPro's Eraser?

Ya, the list stated 1-3% for the soap substance and 1% for fragrance substance, that's roughtly 4% or 4 ounces per 100 ounces. Since the soaps I used have frangrance in them, I calculated about 4% and used that. If I see it overlubricates I will simply cut it in half (or more) with distilled water and alcohol so that the percentage of soap go down. Won't know until I try it so I went with max percentage. The way I see it dawn must contain a lot of detergent and baby shampoo almost none. Hand soap probably doesn't have that much either, mostly product that creates suds.

As for performance, will see. I never used eraser but from the list of ingredients, it's not a complicated product... water, alcohol and soap. So how better can it be?

Would love to read Larry Kosilla's thoughts on this, too bad he doesn't write too often in here.

We usually assume that car products are super complicated and involve a lot of science. That is probably true for some of them, but in this case I don't think it is.

I use a lot of home made products for general cleaning around the house and many of those greatly outperform commercial products. Yet they are super simple to make (vinegar and dish soap are the base for most of them).

Tests will let me know how this mix works. If it's no good at all then all I have done is waste a little time and a few dollars

Give it a shot and let us know how you make out man!!

I'm Assuming sodium laureth sulfate will act as a lubricant, is this correct?

Sodium laureth sulfate (SLS), sodium lauryl ether sulfate (SLES), or ammonium lauryl sulfate (ALS) are: Surfactants, foaming and thickening agents, degreasers, oils/stain removers...that are used in many, many, many products for their cleansing and emulsifying properties. They behave similarly to soaps.

I wonder if using a damp towel, soaked in distilled water would be effective for an IPA wipe down. Anyone ever tried that before?

Dr. Ghodoussi says you can use a water dampened towel to clean the surface of polishing oils when using his products.

I thought I shared it in this article but a quick search didn't find it.

How to Mix IPA for Inspecting Correction Results

I know I have posted it somewhere on this forum.


As for other products?

•Distilled water without any IPA would just be:
a "water-wipedown"...IMHO.

•Water may be the universal solvent...
-but it's a "weak solvent".
-Water, alone, doesn't even remove oils
from a person's hands.
-I see it having a similar difficulty removing
some car-care-polishes' oils.

Here's an example of a "Solvent Scale":

-Toluene: 10/10
-Benzene: 9/10
-Butyl Alcohol: 8/10
-Methyl Ethyl Ketone (MEK): 7/10
-Acetone: 6/10
-Denatured alcohol (Ethanol): 5/10
-Mineral Spirits (Stoddard Solvent): 4/10
-Isopropyl alcohol (IPA): 3/10
-Ethylene Glycol: 2/10
-Distilled Water: 1/10

I personally would not add any soap to my IPA solution for the fact that it leaves a film behind and if I did use soap I would add a drop of baby soap

I'd try it if I was to follow with a paint correction.

No that's not quite what I meant. I was asking instead of using a dry towel for an IPA wipe down, using a damp MF towel instead. I feel damp towels glide across the paint better and pose less threat of installing any micro marring.
