Early morning sunlight slants into the balcony, and the water droplets left on the inner wall of the portable bathtub reflect the fine light spots. Ice cubes melted in last night's ice bath, oil metabolised by the skin after exercising, or crumbs of herbal medicine deposited in the herbal bath all need to be treated and cleaned.
The golden ten minutes after each use is the best time to clean. Before emptying the bathtub, fill it with one-third water and use the palm of your hand to agitate the water stream to flush the inner walls. Focus on the edge joints - this is where bath gel foam or bath salt crystals tend to be deposited. If using the ice bath function, pay special attention to any ice residue that may remain at the bottom, which can form sticky water spots when melted. Avoid cleaners containing alcohol, strong acids or abrasive ingredients. A combination of a teaspoon of baking soda + 500ml of warm water can neutralise grease without damaging the waterproof coating, while a 1:3 solution of white vinegar and water is suitable for removing calcium limescale. Use a soft-bristled toothbrush to lightly brush the drain screen to prevent hair clogging and affect subsequent use.
During the rainy season in the south or in a long term humid environment, the bathtub folding place is prone to black spots. Expand the bathtub completely and lay it flat, dip a cotton swab into hydrogen peroxide and apply it to the mould spots, and then use a nano sponge to gently wipe it off after 20 minutes of resting. Do not use bleach - it works fast but accelerates the ageing of the TPU material. The pigmentation left after the herbal bath, lemon slices can be used to wipe repeatedly; ice bath produced by the frosting water marks, you need to use 40 ℃ below warm water with microfiber cloth to clean up the circle. If the surface of the bathtub appears fogging phenomenon (commonly used in high-frequency ice bath), once a month with a thin coating of glycerin maintenance, can restore the material translucency.
Every fortnight, choose a sunny day and lay the portable ice bath tub completely unfolded in a ventilated area to allow the UV rays to sterilise it naturally. Avoid the midday sun, as excessive sunlight can cause the PVC to become brittle. Turn the portable soaking tub over so that both the inside and outside are exposed to the sunlight evenly, just like a photosynthesis spa for the container.
When the water carries away the last stains and the unfolded inflatable ice bath tub shines pearly in the moonlight, the cleaning process itself becomes an extension of healthy living.
