At Nomad Holiday Rentals properties, we strive to maintain high-quality swimming pools for all guests to enjoy. However, we have observed occasional cases of swimsuit discouloration or staining after use in our pools. This issue is typically the result of a chemical reaction between sunscreen ingredients and chlorine in the water. 
Many sunscreens — especially those containing avobenzone (a common UV filter) — can react with chlorinated water, forming stains or causing fading on swimwear fabrics. This reaction is not specific to our pools but occurs in chlorinated environments worldwide.
Important Note:
Discoloured or stained swimsuits do not qualify for refund or compensation at our properties, as this is a known reaction between personal skincare products and pool chemicals.
To prevent this:
• Shower before entering the pool, as recommended by health and pool authorities.
• Avoid applying sunscreen right before swimming. If necessary, wait 15–30 minutes and rinse excess before pool use.
• Choose swimwear designed for pool use (chlorine-resistant fabrics).
