iv done the titration and the preferred indicator for such a solution is phenalphaline, use a few drops to make it go a bright luminous pink and titrate till clear, not 'cloudy'
Dish washing soap may turn blue or purple when universal indicator is added, indicating it is basic.
The color of washing up liquid on a universal indicator would typically be blue or green, indicating a neutral pH. This is because washing up liquid is usually slightly alkaline, which falls within the blue-green range on a universal indicator scale.
Washing the walls of the flask with distilled water during titration helps ensure all of the solution in the flask participates in the reaction. It removes any residual solute that may be stuck to the walls, preventing errors in the titration results. Additionally, it helps in maintaining the accuracy and precision of the titration by preventing contamination from previous reactions.

To wash out any trace chemicals. These trace chemicals coul affect the titration result. If the burette is clean ( from the lab. store), it will have been through the stores washing machine, so there may be trace solvents left behind.

LDPE is the most cheaper type of polyethylene, suitable for simple objects.
When washing soda (sodium carbonate) is dissolved in water, it creates an alkaline solution. The universal indicator would turn blue to purple, indicating a pH level typically above 9. This color change signifies the basic nature of the washing soda solution.
A fall harness is a device that holds you while you are suspended in mid air. They are very suitable for small window-washing businesses. They help ensure your safety.

yes
the salt in the water makes the fabric weak
no you must hand wash them as the material is not suitable
