I stay in Chennai, due to ocean proximity, all things which are in contact with water (like taps, mugs/buckets, even bathroom floor becomes skiddy, flush mechanism got blocked once coz of this salt build up) needs some regular cleaning. I want to know some chemical which I can add it to the water and drain out the water, all these deposits gets dissolved and flows out along with water. Hope you got my query ?
hmm.. i thought its surf easy wash, or I forgot the branding, sorry, but I use it as its cheaper than other variants and its white is color 
Now-a-days, After wash and taking out clothes, I put some water again in the drum and on the rubber seal, clean it so that no residue of soap water is left, and drain out the water, also keeping my front lid and detergent drawer open now for air circulation
Yep, now my spider is SS ( kochi repair shop type )
And, you mean, if I use phosphate chemicals, corrosion can be delayed and spider life would increase. So, which detergents (or machine powder ) contain correct amount in it, or separate cleaning with phosphate chemicals is preferable I guess ?
