The pH of 5% vinegar is between 2 and 3. The color of universal indicator in that range is reddish-orange.
Universal indicator turns red when added to vinegar, indicating that the vinegar is acidic.
Because oven cleaner contains Sodium Hydroxide (Na OH), a 'strong' alkali/base, to dissolve the grease, it would change Universal Indicator a deep blue/purple colour.
Universal indicator changes to green when sodium bicarbonate is added.
A universal indicator changes to red when mixed with a strong acid.
Citric acid is generally colorless in universal indicator. It is a weak acid, so it does not exhibit a strong color change in the indicator solution.
Universal indicator turns red when added to vinegar, indicating that the vinegar is acidic.

Universal indicator changes to red/orange when hydrochloric acid is added, indicating that the solution is acidic.
When acid is added to universal indicator, the indicator will typically change to shades of red, orange, or yellow, depending on the strength of the acid.
A universal indicator changes to a greenish-blue color when mixed with ethanol.
When universal indicator is added to milk, it will change to a blue or purple color, indicating a basic pH level.
When sugar is mixed with universal indicator, it typically does not change color as the indicator is primarily used to measure pH levels in solutions, not sugar content. The indicator will only change color based on the acidity or alkalinity of the solution it is in.
Green is the color that universal indicator turns to when it is neutral.
